Purpose Wireless communication systems provide a two-way information transfer (voice and data) between a base station and multiple mobiles within a given area. Repeaters are used to extend the transmission range if weak signal transmissions occur within the coverage area due to indoor applications, topological conditions or distance from the transmitter. In the downlink path, the repeater picks up the signal from a donor antenna of an existing cell, amplifies and re-transmits it into the required dark spot. In the uplink direction, the repeater receives signals from mobile stations present in its coverage area and re-transmits the signals to the corresponding base station. In the downlink (DL), the Node AM4 picks up signals coming from the base station, filters them, amplifies them, and retransmits them to the mobile. In the uplink (UL), it picks up signals from the mobile, filters them, amplifies them, and retransmits them to the base station. The Node AM4 constantly monitors the quality of the signals passing through it. 2.2. The Node AM4 Repeater Note: The denomination "Node AM4" says that this RF repeater is equipped with slots for 4 RF cards / dummy cards. Universal multi-band, multi-service repeater for mobile applications. A coverage solution and a universal choice for selective transmission of interleaved sub-bands for amplification of GSM, EDGE, TDMA, CDMA, WCDMA, HSPA, HSPA+, and LTE signals within multiple frequency bands. Supports up to 4 frequency bands (with single-band RF cards only) or currently up to 7-8 frequency bands (with dual-band RF cards) in a single chassis with fully integrated multi-band combiner and modem for remote monitoring and control. Software-based repeater platform enables on-the-fly filter changes and development of new features and capabilities without expensive hardware upgrades. Channel and band selective automatic gain/ power control for mobile multi-operator and public safety applications. Available in both medium and high power classes (for dual-band RF cards, medium power class only) to enhance coverage in trains and ferry applications. Automatic Frequency Allocation enable self-acting repeater reconfigurations based on received GPS position. Intuitive auto setup and help screens for easy system configuration, minimizing setup time and reliance on expensive and bulky test equipment. MF0121ACP_uc.docx Manual for Node AM4 Page 17 2.

Caution: Risk of injury by the considerable weight of the unit falling. Ensure there is adequate manpower to handle the weight of the system. Caution: Risk of serious personal injury by equipment falling due to improper installation. The installer must verify that the supporting surface will safely support the combined load of the electronic equipment and all attached hardware and components. Only use sufficiently dimensioned screws for mounting and make sure the mounting material is adequate for the mounting surface. 2. 3.1.2. Property Damage Warnings for Mechanical Installation 1. Attention: Do not install the unit in a way or at a place where the specifications outlined in the Environmental and Safety Specifications leaflet of the supplier are not met. 2. Notice: Due to power dissipation, the unit may reach a very high temperature. Ensure sufficient airflow for ventilation. When mounting the Node AM4 into a train, a temperature test in maximum configuration (i.e. 4 RF cards) must essentially be made. A minimum air flow of 50 m/h is required where the maximum air flow of the Node AM4 is 220 m/h which will be reached at an environmental temperature of around 45C and above. We suggest to supply the repeater at the air inlet with fresh air and to conduct warm air at the air outlet off the Node AM4 without feedback in order to avoid a 'thermal short-circuit'. 3. Notice: It is recommended only to use the mounting hardware delivered by the manufacturer. If any different or additional mounting material is used, ensure that the mounting remains as safe as the mounting designed by the manufacturer. Ensure that the static and dynamic strengths are adequate for the environmental conditions of the site. The mounting itself must not vibrate, swing or move in any way that might cause damage to the unit. The specifications for stationary use of the unit must not be exceeded. Note: Exceeding the specified load limits may cause the loss of warranty. 4. Notice: Only use sufficiently dimensioned screws for mounting and make sure the mounting material is adequate for the mounting surface. 5. Notice: Observe that for M12 connectors the nominal torque is 1.0 N-m. 6. Notice: When connecting and mounting the cables (RF, mains, ...) ensure no water can penetrate into the unit through these cables. 7. Notice: Do not operate the repeater without terminating the antenna connectors. The antenna connectors may be terminated by connecting them to their respective antennas or to a dummy load. Unless otherwise agreed to in writing by CommScope, CommScopes general limited product warranty (http://www.commscope.com/Resources/Warranties/) shall be the warranty governing the Node AMs, including the installation, maintenance, usage and operation of the Node AMs. MF0121ACP_uc.docx Manual for Node AM4 Page 19 3.

Installation 3.1.5. RF Card Installation Note 1: To ensure shock protection of the DC connectors and main board, the RF cards are packed separately for transport. Installation of the RF cards is recommended after the Node AM unit itself has been mounted according to the following instruction:

Use the guide rails on top and bottom to fit in the RF card smoothly. Fasten* the four neck-collar screws tight M3x16 mm ensure watertightness. For the specified torque refer to the according table in chapter 5.2 of Components.

* First, Replacement just slightly to tighten the screws crosswise in order to avoid cant, and when all four screws are positioned correctly, fasten them tight. Note 2: Depending on the respective frequency range, the maximum equipment of 4 RF cards is not necessarily required but all unused slots need to be assembled with a dummy card for sufficient airflow and provided IP class. Note 3: It is mandatory that one RF card is installed into slot 1 as a (passive) dummy card does not fit into slot 1. A dummy card has to be installed into slots with no RF card to guarantee correct airflow and watertightness for the active components. For layout please refer to figure 4 2 Exemplary layout of a Node AM4, maximum equipment in chapter 4.3 Components. Note 4: It is recommended to disconnect the Node AM4 from mains (power-supply line) before an RF card is mounted or dismounted. In case the Node AM4 is not allowed to be disconnected from mains, the RF card which needs to be replaced must be disabled via software in the Technician page before removing it. This is to avoid possible damage when inserting the new RF card Note 5: Please observe that the RF cards must always be packed separately for transport.

Interconnection Cabling The required cables are part of the delivery of the RF cards. Connect the individual BTS band ports of the combiner (if equipped) to the BTS ports of the according band of the RF cards. Connect the individual Mobile band ports of the combiner (if equipped) to the Mobile ports of the according band of the RF cards. However, the antennas may also be mounted directly on the RF card connectors. figure 3-2 Example for interconnecting cabling for a Node AM4 (combiner with three pairs of band ports) 3.2.5. Connection of the Antenna Cables The antenna connectors of the Node AM combiner are N female. However, the antennas may also be mounted directly on the RF card connectors which are QN. All connectors are located at the front of the cabinet. An operator should refer to the documentation of the cable connector manufacturer for best mating procedures. Furthermore, the bending radius of the antenna cables should be maintained at all times. There are several issues to be considered when selecting the cable and antenna types. In applications such as trains and ferries, it is highly recommended to use directional antennas with good front-back-ratios (40 dB is typical) because they improve isolation and cell-site selectivity. Smaller diameter cables are less expensive and easier to install but have worse performance. MF0121ACP_uc.docx Manual for Node AM4 Page 25 2b 3b Multiband combiner 1a 1b 2a 3a 4a 4b 3.

The positioning of the power cable with the illustrated connector is adjustable by loosening the 1 lock nut. Use an appropriate torque wrench

(wrench size 27 mm) to observe torque of 2 N-m. The cable can be turned by maximally 45 to the left or right from the vertical position as illustrated. This adjustment degree is irrespective of the delivery condition which is not necessarily the vertical position. After the adjustment, tighten the nut again. Page 32 MF0121ACP_uc.docx Manual for Node AM4 3. Installation 3.2.9. Connection to the Node AM The Node AM is set up, configured and monitored using a PC. The connection to the Node AM can be established locally via an Ethernet cable or remotely via modem. The local connection is easy to set up and much faster in operation. The local connection should be used for initial setup and whenever the operator is at site. 3.2.9.1. Setting up the Local Connection A standard Ethernet CAT5 cable is supplied with the Main Unit of the Node AM. Connect the cable to the Node AM and the network port on the PC. The Node AM hardware supports 10 or 100 megabit / sec Ethernet connections. After the connection is made properly, the red and green LEDs near the Node AM network connector will flash. Likewise, the network connector on many PCs has LEDs that indicate when a hardware connection is established. The network hardware will determine the highest speed supported by both devices. figure 3-6 Connecting the CAT5 cable to the Node AM for the local connection The operating system of most PCs will automatically establish the hardware and software network connection. No setup or system changes are required on the PC to establish a local connection with the Node AM. Normally, the connection can be made either before or after the Node AM and PC are powered up. If there are problems, make sure the cable is fully inserted at both ends. Make sure the PC network driver is not fixed at 1 GB/second. With the cable connected restart the PC. If that fails, restart the Node AM. 3.2.9.2. Setting up the Remote Connection Setting up the remote connection is slightly more involved than setting up the local connection. A separate manual is provided to explain how to setup the remote connection. Via the remote connection, the operator can monitor and control the Node AM using the Web browser interface remotely. In addition, the remote connection may be used for an OMC-type software platform and SMS alarm forwarding. MF0121ACP_uc.docx Manual for Node AM4 Page 33 4. Functional Description 4. Functional Description 4.1. Architecture The Node AM4 is designed to amplify signals between multiple mobiles and a base station. The unit consists of a filter and amplifier chain in the downlink and one filter and amplifier chain in the uplink. The uplink and downlink paths are connected via a duplexer on both ends of each path. After that the signals are combined by the crossband coupler with the other frequency bands. In the uplink path, a signal originating from the mobile is divided by the crossband coupler into the different frequency bands and is separated from the downlink signal via the UL IN duplexer. It is then amplified by a low noise amplifier (LNA), which is like the duplexer part of the RF card. The RF card down-converts the signals to the IF and converts the analogue signal into a digital signal. Digital filtering / signal processing is done at the main board of the subrack with single band RF cards, and with dual-band RF cards in the cards themselves. Then, the digital signal is converted into an analogue signal, is up-converted and amplified. Finally, the signal is sent to the PA and combined with the downlink signal. After that the signals from all RF cards are combined at the crossband coupler and forwarded to the Base Station port of the Node AM4 system. In the downlink path, a signal originating from the base station is divided by the crossband coupler into the different frequency bands and is separated from the uplink signal in the donor duplexer. It is then amplified by a low noise amplifier (LNA), which is like the duplexer part of the RF card. The RF card down-converts the signals to the IF and converts the analogue signal into a digital signal. Digital filtering / signal processing is done at the main board of the subrack with single band RF cards, and with dual-band RF cards in the cards themselves. Then the digital signal is converted into an analogue signal, is up-converted and amplified. Finally, the signal is sent to the PA and combined with the uplink signal. After that the signals from all RF cards are combined at the crossband coupler and forwarded to the mobile port of the Node AM4 system. Apart from the difference in digital signal processing as explained in the sections above, the functionality of dual band and single band RF cards is principally identical in both the UL and DL paths. For an overview of the individual components, please refer to chapter 4.3 Components. 4.2. Features 4.2.1. Digital Channel Filters The Node AM has a multitude of digital filters. The maximum bandwidth of each filter is 5 MHz. If a greater bandwidth than 5 MHz is required, two or more sub-band filters are linked together without increased amplitude or delay ripple. The number of sub-band filters is automatically allocated and shown by the repeater software (Technician Setup page). The user has to select the downlink start and stop frequencies (wide-band filter load) or centre frequency and filter bandwidth (narrow-band-filter loads) of each sub-band filter. For further information regarding sub-band filter settings refer to the Users Manual for the Node AM software. Page 34 MF0121ACP_uc.docx Manual for Node AM4 4. Functional Description 4.2.2. Frequency Hopping The Node AM repeater supports base band hopping (BBH) and synthesized frequency hopping (SFH) in GSM networks. For base band hopping (BBH) even channelized digital filters may be used. For synthesized frequency hopping (SFH) band selective filters are needed. 4.2.3. Filter Types Please observe that the selectivity of the filter types is not yet available with the current software version. At the moment only the filter type Normal will be active even if another filter is selected. From which software release onwards the selectivity described in the following will be implemented in future is not defined, yet. In future, there will be different filter types available for each sub-band. These filter types are:

Normal (good selectivity and group delay) Wide (low selectivity and low group delay) Narrow (high selectivity and high group delay) Auto (preferred mode) It is advisable to select the Auto filter. In this case the repeater selects the best filter type (normal, wide or narrow) automatically. The choice of filter type depends on the input signal strength and position of the adjacent channel signals. If narrow, strong adjacent cannel signals are received, the Narrow filter is selected. If the adjacent channels are far from the desired band/channel, the Wide filter type is used. For all other configurations, the Normal filter is selected. 4.2.4. Status Information The Status and Reports menu, which is accessible via the home page of the web interface, provides information about the current gain, output level and receive signal strength indication (RSSI) values. The RSSI provides controlling and monitoring of the receive level of a Base Station (DL RSSI) or user equipment (UL RSSI) to a Node AM. It measures the level of the input signal by detecting the RF and converting the analogue level into a digital value. The data are processed and evaluated by software. A corresponding measurement is also made for the output levels. RSSI measurements are done for each band segment; for further details please refer to the Node AM/ Node AM SW manual.

Functional Description Front view 3-D-view figure 4-3 Node AM4 2-band combiner (800-900 and 1800-2100 MHz) with two pairs of band ports Via an additional external 10 dB directional coupler the modem can be connected using the direct Modem RF port [1]. In case an external 10 dB directional coupler cannot be used, an integrated directional probe (QMA connector at the rear side of the combiner;

see also figure 4-19) may be used to supply the modem with RF signals. :

Further optional ports of the combiner are the GPS port [2] with optional GPS LNA DC supply (for the corresponding connections on the rear side see also figure 4-19) as well as two 30 dB coupling probes [3], which can be used for testing purposes for the antenna ports. Page 38 MF0121ACP_uc.docx Manual for Node AM4 4. Functional Description 4.3.2. Digital Channel Modules (DCM) / RF Cards The digital channel module (DCM) is the RF digital-converter in both directions for Downlink and Uplink. The Downlink and Uplink will be separated in the duplexer and the desired signal will be amplified by an LNA which is like the duplexer an integrated part of the RF card. The RF card down-converts the signals to the IF and converts the analogue signal into a digital signal. Digital filtering / signal processing is done at the main board of the subrack with single band RF cards, and with dual-band RF cards in the cards themselves. Then, the digital signal is converted into an analogue signal, is up-converted and amplified. Finally, the signal is sent to the PA (internal PA or mounted on the RF card) and combined with the other link in the second duplexer. The following figure shows the single band DCM, RF cards:

figure 4-4 Single-band DCM, RF card, low / medium power (left) and high power with additional DL amplifier (right) Optionally, medium power dual band RF cards are available, by which two bands, for instance the 800/900 bands or the 1800/2100 bands, can be combined in one module. Thus, the maximum number of bands per Node AM can be increased to up to 8*. Apart from the difference in digital signal processing the functionality of dual-band and single-band RF cards is principally identical.

* up to 7 with 680 W PSU explained above, as figure 4-5 Dual band DCM, RF card (medium power) With certain RF cards, use of a slot duplexer is obligatory. This duplexer is installed in an RF card slot, i.e. if such a duplexer is equipped, maximally three RF cards are available. For details on the card types see chapter 8. MF0121ACP_uc.docx Manual for Node AM4 Page 39 4.3.3. Dummy Card 4. Functional Description figure 4-6 Dummy card Note: All unused slots need to be assembled with a dummy card for sufficient airflow and provided IP class. Note: Empty slots of the Node AM will generate an alarm. Note: Do not install the dummy card into slot 1. Note: Depending on type of fan unit (bottom or backside) different dummy cards need to be equipped in empty slots. 4.3.4. Power Supply Unit The power supply unit is mounted in the interior cabinet of the Node AM4. This device transforms mains power into predefined DC voltages. When performing maintenance, ensure that all circuits are voltage-free and that the Node AM4 is disconnected from mains. figure 4-7 Power supply (DC/DC type), front and back In units with a 680 W power supply (AC or DC), observe the RF card limitations specified in chapter 7.1. With the 780 W DC PSU there are only limitations for a mains voltage from 24 to 36 Vdc which are also specified in chapter 7.1. To decide which type of PSU is equipped, look up the HID of the PSU on the Serial and ID Numbers page of the SW

Reconnect the DC connector to the "Battery" connector at the UI2 board. MF0121ACP_uc.docx Manual for Node AM4 Page 47 4. Functional Description 4.3.6.3. Optional Modems Note: As optional modem, different types can be used for the Node AM: PHS8

(successor of HC25), PLS8 (for LTE), TRM-5, and MC88 modems. The layout of all types is alike. In the following, the general term "modem" is shortly used, referring to any of these types. GPS is only supported by PHS8 (formerly HC25) and PLS8. Modem type RV50X is supported but it is not available from CommScope. It can only be ordered directly from the manufacturer. A wireless modem is used to establish a remote connection to the Node AM. The connection may be circuit switched or packet switched and is used to change the parameters of the unit, check and clear alarms, or collect measurement and quality statistics. Furthermore, the modem is requested at the Node AM to alert the operator when there is an alarm. The modem settings (i.e. which type of modem, Initstring, etc.) may only be changed locally. Should a different modem be used, the operator should ensure that the settings are changed prior to leaving the site. For technical data of the individual modems, see chapter 7.5.1 HC25 / PHS8 / PLS8 /

MC88 / TRM-5. For the technical data of type RV50X, refer to the data sheet of the manufacturer. Initstrings The initialization string (abbreviated by initstring) depends on the operators network and the modem. It may be necessary to adjust the initstring in the field. When a modem is selected in the Node AM web interface the default initstring for this modem is suggested. The initstrings for the different modems are listed in the software description for the Node AM. Modem Installed (valid for HC25 / PHS8 / PLS8 / MC88 / TRM-5) The modem allows remote control and maintenance of the Node AM. Parameters may be changed; alarm and measurement be acknowledged and collected by the OMC. The modem is installed in the side tube of the unit. To avoid a collision between modem connectors and combiner

(especially with 4-way combiners), an adapter kit for modem installation is used (see chapters 5.2.2 and 8). statistics may exemplary figure 4-18 Modem installed, exemplary Page 48 MF0121ACP_uc.docx Manual for Node AM4 4.

Maintenance Caution: The unit reaches high temperature in operation. Risk of burns by hot surface. Do not touch the unit before it has sufficiently cooled down. Notes:

The Node AM does not require any preventative maintenance measures apart from the Battery Backup Unit (BBU). It is recommended to replace it after 4 years of operation (see chapter 4.3.6). We recommend checking the cleanliness of the unit and in particular of the fan unit at appropriate intervals depending on the degree of dust and dirt at the installation site. If necessary, any dusty or dirty areas / parts should be cleaned at regular intervals, which also depend on the degree of dust and dirt at the installation site. For cleaning, the following procedure is recommended: use an industrial vacuum cleaner and, first, vacuum the outside of the unit. For inside cleaning, remove all plug-

in units (as well as the fan unit) according to the instructions in the following chapter, and then, vacuum the fan unit, the cooling fins of the plug-in units as well as the complete interior of the Node AM. In the event of a malfunction, the user should check the status of the antennas, feeder cables, connectors, and mains power before replacing any components. When sending back the unit, use an appropriate packaging; see chapter 7.3. We strongly recommend using the original packaging. The transport protection cover (see chapter 3.1.3) should also be installed for units with bottom type fan unit (see chapter 5.2.7.2). For a better shock protection of the DC connectors and main board the RF cards must be packed separately. 5.2. Replacement of Components Read and observe chapter 1.2. Maintenance of the Node AM should be performed on a field replaceable unit (FRU) basis only. Do not damage the warranty labels on the components as this voids the warranty. Unless otherwise agreed to in writing by CommScope, CommScopes general limited product warranty (http://www.commscope.com/Resources/Warranties/) shall be the warranty governing the Node AMs, including the installation, maintenance, usage and operation of the Node AMs. The spare parts list contains only units that can be replaced without tuning or soldering work. It is not recommended to replace any components inside the Node AM itself, except, RF cards, combiner, and modem. Regarding the replacement of a PSU observe the corresponding Note in chapter 5.2.5. Note: Defect parts should only be replaced by original parts from the supplier. All interventions inside the housing are at ones own risk. Page 52 MF0121ACP_uc.docx Manual for Node AM4 5. Maintenance Note: During maintenance ensure that the unit has been disconnected from mains. Note: Before disconnecting any cables, label any unlabeled cables to ensure correct reconnection, and check the switch positions of the removed part to set the switches of the new part accordingly. To replace an FRU, use the appropriate tools. The tools are provided along with the equipment. Replacement tools may be ordered from the supplier. SMA connectors have a specified torque of 60 N-cm. All screws have a right-hand thread, turn the tool clockwise for tightening and counter-clockwise for loosening. Use an appropriate tool to fasten and unfasten connectors and screws. Do NOT overtighten the connectors or screws!

Note: Observe that all components have watertight sealings. After replacement of components all screws have to be fastened tight to ensure watertightness. Note: After the replacement of a component, check whether the system has to be levelled anew. Note:

Note: Do not forget to reinstall the splash water shield and vandalism cover (if this option is installed) after the replacement procedure to ensure safe operation. It is recommended to disconnect the Node AM from mains (power-supply line) before an RF card is mounted or dismounted. In case the Node AM is not allowed to be disconnected from mains, the RF card which needs to be replaced must be disabled via software in the Technician page before removing it. This is to avoid possible damage when inserting the new RF card. If any FRU not contained in the following chapter needs to be replaced, please contact customer service for additional instructions. Page 54 MF0121ACP_uc.docx Manual for Node AM4 5. Maintenance 5.2.1. Multiband Combiner Danger: Electrical hazard. Danger of death or fatal injury from electrical current inside the unit in operation. Before opening the unit, disconnect mains power. Danger: Electrical hazard. Danger of death or fatal injury from electrical current due to a possible short-circuit caused by incorrect handling. Make sure the system has been correctly grounded (earthed) as described in chapter 3.2.3 and connected via external circuit breaker (see chapter 3.2.8). Caution: Rotating fans. Risk of injury in operation. Wear tight-fitting clothes and disconnect mains before working inside the unit. Note: Removal and installation of a combiner on-site must only be done by a service technician of CommScope or by a qualified person authorized and trained for this procedure who is observing the corresponding safety procedures required by local, regional and country-specific regulations which have to be observed during all times of this procedure. in figures this chapter show Notes:

The the combiner type with three pairs of band ports. The procedure is exactly the same for combiners with two band port pairs. Unscrew the combiner and pull it out carefully with your hands. As the long hole of the combiners carrier plate is hooked into a screw of the modem mounting plate, this is pulled out to a certain degree, as well:

Mounting plates of combiner and modem connected by screw locked into long hole (seen from both sides). MF0121ACP_uc.docx Manual for Node AM4 Page 55 5. Maintenance Unhook the plates and disconnect all cables from the combiner. Remember their positions for later reconnection. (For replacement of components on the carrier plate, now refer to the corresponding chapter.) At four band combiners, the combiner is tied to the carrier plate by a mounting plate that is fixed with screws. To avoid a collision between modem connectors and combiner (particularly with 4-way combiners), an adapter kit for modem installation is used (see figure 5 1 and chapter 8). Exchange the combiner and re-connect all cables at the correct positions. Note: In case of upgrading with a different type of multiband combiner, make sure that the operating frequency band of the modem still fits to the combiner frequency bands. Caution: Before sliding the new module in, make sure that no cables inside, e. g. from the PSU, obstruct the way and may get squeezed or damaged in the process. Make also sure that no cables get disconnected by accident. In case of obstructing cables that may get damaged, send the unit back to the supplier for repair. Carefully slide in the modem carrier plate, using the guide rails provided at the top and bottom of the slot for positioning the module correctly. Then, reconnect the modem and combiner plates by hooking the screw of the modem plate into the long hole of the combiner plate. Guide rails Position the combiner plate in the same guide rails as the modem plate and slide in the combiner carefully, also pushing the modem carrier plate back in. Attention: Be careful with all cables connected. Do not squeeze or damage any cables, and make sure that no cables get disconnected by accident. Fasten the screws of the combiner tight to restore watertightness (for screw positions, see illustration at the beginning of the procedure). Page 56 MF0121ACP_uc.docx Manual for Node AM4 5. Maintenance 5.2.2. Modem / Battery 1. Caution: Electrolyte inside. Risk of health hazards associated with electrolyte leakage. Do not disassemble, puncture, modify, drop, throw, or cause other unnecessary shocks to batteries. 2. Caution: High current if shorted. Risk of injury by high current. Do not short circuit the batteries. 3. Caution: The batteries might be hot. Risk of burns by hot surface. Do not touch the batteries before they have sufficiently cooled down. Do not put the batteries to the garbage but dispose of them properly according local and/or regional regulations. Notice:

Currently, the battery condition is only detected at shutdown, by making sure the battery has enough charge to allow a complete shutdown process. If the battery is dead, missing, or not able to hold a charge lasting more than a minute or two (the time for a normal shutdown, which could be up to 10 minutes), this will be noticed by the software at the next power up and an alarm raised. However, this means a good battery condition can also only be detected at shutdown. If a bad battery is replaced with a good battery in the field, the alarm will not be cleared immediately at the next bootup. Instead the system will have to have a normal power shutdown and then the alarm will be cleared at the following bootup. So, the procedure for replacing a failed battery should be:

1. Shutdown the system. 2. Replace the battery. 3. Power up (alarm will still be raised). 4. Shutdown the system. 5. Power up (alarm will now be cleared). If this is not done, the alarm will be only cleared after the next shutdown and power up event of the system. Also, observe that an alarm is raised once the battery disconnect button on the UI1 board is pressed and the unit is powered up again. To delete the false alarm, the unit has to be shut down and powered up again. During the shutdown, the battery disconnect button must not be pressed. Notice: For the replacement procedure, also observe the warnings in chapters 5.1 and 5.2.1. Notice: For tightening SMA connectors, always use an appropriate torque wrench:

Modem and battery are located on a carrier plate located behind the combiner carrier plate. Thus, for replacing the modem or the battery, the combiner has to be removed first. To do so refer to chapter 5.2.1, observing the corresponding warning messages. MF0121ACP_uc.docx Manual for Node AM4 Page 57 5. Maintenance The long hole of the combiners carrier plate is hooked into a screw of the modem mounting plate, so both plates will be pulled out together:

Power Supply Danger: Electrical hazard. Danger of death or fatal injury from electrical current inside the unit in operation. Before opening the unit, disconnect mains power. Caution: Rotating fans. Risk of injury in operation. Wear tight-fitting clothes and disconnect mains before working inside the unit. Note: We strongly recommend not to replace a defect PSU on-site but to send the Node AM to CommScope for repair. A replacement on-site must only be done by a service technician of CommScope or by an equally trained person who has the necessary qualifications to carry out such a replacement as well as the corresponding safety tests demanded by local, regional and country-specific regulations. Note: Replacing a PSU with another type (e.g. 680 W with 780 W type) is not possible on site. To remove the original power supply

MF0121ACP_uc.docx Manual for Node AM4 Page 65 5. Maintenance 5.2.6. RF Card Exchange / Upgrade with Additional RF Cards Caution: Rotating fans. Risk of injury in operation. Wear tight-fitting clothes and disconnect mains before working inside the unit. Notes:

This instruction is also valid for the slot duplexer. It is strongly recommended to disconnect the Node AM from mains (power-

supply line) before an RF card is mounted or dismounted. In case the Node AM is not allowed to be disconnected from mains, the RF card which needs to be replaced must be disabled via software in the Technician page before removing it. This is to avoid possible damage when inserting the new RF card. Observe that the RF cards must always be packed separately for transport All unused slots need to be assembled with a dummy card for sufficient airflow and provided IP class. Before upgrading or when replacing single-band with dual-band cards, observe the limitations for the number of dual-band cards that may be equipped as specified in chapter 7.1. Replacing a single-band with a dual-band card impacts the share of available filters. A total of 48 (backplane-controlled) filters can be defined at freely variable proportions for all single-band cards equipped. For dual-band cards, these filters are not available but each dual-band card provides additional 32 wide-band filters, which can be variably shared among the two bands of this card only. Thus, if a single-band card for which more than 32 filters were defined is replaced, these can no longer be provided by the dual-band card. This chapter shows the single-band cards but it is valid for dual-band cards as well. To replace an RF card or to upgrade the Node AM with additional RF cards, proceed as follows:

To remove an RF card / or dummy card (in case of an upgrade):

Disconnect the cables. Loosen the four socket head cap screws M3x16 mm) and take the RF / dummy card out. To install the RF card:

Use the guide rails on top and bottom to fit in the RF card smoothly. Note: Fasten the screws of the RF card tight to restore watertightness. To do so, first, just slightly tighten the screws crosswise in order to avoid cant, and when all four screws are positioned correctly, fasten them tight. Use the guide rails on top and bottom to fit in the RF card smoothly. Reconnect the cables. Page 66 MF0121ACP_uc.docx Manual for Node AM4 5. Maintenance Note: If an RF Card is exchanged by a card of another type, e.g. an AF2125 by an AF1825/2125, resetting this card via the Technician Setup menu of the SW

(see SV manual) is recommended. In case of an upgrade, also observe the following:

If the multiband combiner has to be upgraded as well (i.e. two-band combiner to three-

band combiner), refer to the instructions in chapter 5.2.1 for the exchange. The required RF cables are part of the delivery of the RF card. Connect the individual BTS band ports of the combiner to the BTS ports of the according band of the RF cards. Connect the individual Mobile band ports of the combiner to the Mobile ports of the according band of the RF cards. 5.2.7. Fan Unit 5.2.7.1.

Detailed System Description Single-Band Cards Node AM RF cards convert the RF into digital signals and transfer them to the Node AM rack for digital filtering. The digital architecture allows sub-band filtering and is shared between all RF Cards inserted into the Node AM rack. The Node AM4 can provide up to 48 filter resources (up to 5 MHz each). Additional filtering capability is provided by on-

card digital signal processing at dual-band RF cards to satisfy increasing demand of sub-

bands for further RF-bands or MIMO deployments. When the sub-band bandwidths are greater than 5 MHz, the filter resources are grouped together, without phase or amplitude ripple, where the sub-band is defined by a start and stop frequency. The total number of used filter resources is determined by adding the number of filter resources required for each sub-band. For example, if there are three sub-bands with 4 MHz for the first sub-band, 11 MHz for the second sub-band, and 20 MHz for the third sub-band, then 1 filter resource is required for the first sub-band, 3 filter resources are required for the second sub-band and 4 filter resources are required for the third sub-band. The total number of used filter resources in this example is 8. However, the maximum available bandwidth (240 MHz) will only be achieved with sub-band bandwidths of integer multiple of 5 MHz. The following diagram shows examples for filter resources allocation:

However, basically all measures Detailed System Description Dual-Band Cards With the increasing demand for mobile communication, additional radio frequency (RF) bands are globally assigned to meet that demand. In addition, better utilization of the radio spectrum is being addressed by Multiple-In Multiple-Out (MIMO) antenna technology and the communication link capacity result in an increased number of parallel operated radio front ends. In response to this trend, CommScope has enhanced the radio band capacity of its existing Node AM platform by providing Dual Band RF cards. Following a software upgrade, two medium power RF front ends can be operated in the same space of a legacy single band plug-in module. Thanks to the on-card digital signal processing functionality, up to 32 filter resources (0.2 5 MHz each) are available per dual card. Depending on the upgrade goal, i.e. increasing the number of RF bands or MIMO performance, dual band RF cards for inter-

band, e.g. 8/9 or 18/21, combination are available. When using CommScopes Node AM chassis in situations where the sub-band bandwidths are greater than 5 MHz and where the sub-bands are defined by a start and stop frequency, the filter resources are grouped together, without phase or amplitude ripple. The total number of used filter resources per dual band card is determined by adding the number of filter resources required for each sub-band in both RF bands together. For example, if there are three sub-bands with 200 kHz for the first sub-band and 10 MHz for the second sub-band in the 1800 MHz band and 20 MHz for the third sub-

band in the 2100 MHz band then one filter resource is needed in the first, two in the second, and four in the third sub-band. The total number of filter resources used is seven. Example of filter resources allocation (up to 5 MHz wide):
