Reframe with optical signal from the C-hub. Transmit the composite signal to next level E-hub and RU. Fig. 5: E-hub front view 3.3.4 HPRU Conduct digital-analog conversion and power amplification of the input signals. Each RU can support up to 2 RF signals output with different frequency bands. Redistribute WLAN and small cell signals via an Ethernet port. Achieve radio coverage through the antenna feeder system for signals of all standards and frequency bands. Fig. 6: HPRU 12 of 20 936.5465 0.92 4 WLAN Access (Wi-Fi) Each E-hub has 6 electrical ports, GE1 to GE6, which support up to 6 LAN signals. LAN signals are input on the GE1 to GE6 ports and output from the corresponding OP1 to OP6 ports. The signals are then transmitted to the RUs via optical signals over optical fibre and output from the GE port on the RU. Each RU connects to an AP device through their respective GE port. Thus, 6 independent Gigabit Ethernet transmission channels can be completed. See Fig. 7 for connection details and Fig. 8 for application scenario. The flow path of the signal is: Input LAN signals E-hub RU AP POI Antenna-

feeder system. The following applies:

Each electrical port (GE1 to GE6) must correspond to an optical port (OP1 to OP6), i.e. GE1 should correspond to OP1, GE2 should correspond to OP2, etc. WLAN signal input on GE1 is then sent out on OP1. If there are multiple access points (AP) that are connected to more than one cascading RU in a signal chain, the WLAN signal will only be output from one of the RUs, with the priority being RU1 > RU2 > RU3 when selecting which RU the signal will be output from. If there is only one AP device, then the WLAN signal is always output from the RU that is connected to the AP.

Do not connect the unit to the power supply during installation. Connection to the power supply must be performed by a trained, qualifi ed and author-

ised specialist. Warning Crushing hazard. 19" racks can be very heavy. At least two persons are required to carry 19" racks to avoid injuries. 4.1.1 Requirements for the C-Hub Kathrein offers racks with the necessary characteristics. If other racks are used, these must also satisfy the following required characteristics. The K-BOW system rack must be installed upright. This can be done by adjusting the height-adjustable rack feet, using a spirit level. A 5-pin CEE socket and distributor according to DIN 60309 is required for the power supply of each circuit in the power distribution bars. Two sockets are required for each 42-HU rack. One socket is required for the 24-HU rack. Each 5-pin CEE socket must be protected by a D curve miniature circuit breaker (Europe) with 3 10 A (delay fuse). For the installation of the components, the rack must be accessible from at least one side. To make installation of the components in the rack easier, we recommend that the rack is accessible from two sides. The rear panel and side panels must contain lockable access doors. The doors must extend over the entire rear and side panels. If you use racks which are not recommended by Kathrein, these racks must comply with the following specifications:

All height units not used must be blanked off. The door must permit the passage of air over its entire surface, for instance by perforation. The cooling air must flow through the rack from the front between the K-BOW components, upwards and to the back where it is exhausted. 936.5467 0.92 23 of 50 Installing the C-Hub 4.2 Power Distribution Bars Notice Risk of reduced operational reliability because of power failure. Make sure that the 230 VAC power supply to the K-BOW system rack satisfies the following conditions:

3 or 6 power distribution modules are used in order to ensure redundancy of the power supply; see the planning document. Furthermore:

For reasons of operational reliability (redundancy), each power distribution module must be connected to a different phase. Each of the 3 PSUs of the PDU, BSR, FSR is connected to its own power distri-

bution module. A maximum of 4 PSUs may be connected to each power distribution module. The power available must correspond to the power consumption of the K-BOW system. The required amount of power supplies is specified in the rack layout plan depending on the system design. The electrical fuses and protective elements in the power supply must match the power consumption of the K-BOW system and satisfy the national regulations. The grounding conductors (potential equalisation) and data conductors (incl. hybrid cables) must at all points be at least 50 mm apart. Therefore, use separation strips in cable ducts and on cable trays. A. Install the power distribution modules to the power distribution bar on the left-hand side of the rack ( in Fig. 6). In doing so, install the first three modules with the red arrow facing upwards, and the next three modules (if required) with the black arrow facing upwards. B. Plug in the power cable on the top of the power distribution bar:

For the three modules in the red circuit (red arrow faces upwards), use the connection on the left side ( in Fig. 7).

Connection to the power supply must be performed by a trained, qualifi ed and author-

ised specialist. Notice Risk of damage to the cables!

There is a risk of malfunctions if cables are damaged because they are bent more than the minimum bend radius permits, or if cable fasteners are overtightened. Such damage is not evident from outside and will lead to signal errors. Comply with the K-BOW Cabling Guidelines when laying (bending) and fi xing optical fi bre and other cables. When doing the work described in this chapter, comply with the cabling rules in the document K-BOW Cabling Guidelines. Perform the cabling strictly as described in the document K-BOW Setup Manual and in the planning document for the system. Throughout all cabling work, comply with the minimum bending radii1) for the cables;

this is particularly critical for fibre optic cables and hybrid cables. Fasten the cables as follows:

If possible, use Velcro straps2) to secure fibre optic cables, hybrid cables, coax cables3) and other sensitive cables. If you only have plastic cable ties: Tighten the cable ties only to such an extent that the cables are by no means compressed, deformed or squeezed. If possible, only use plastic cable ties for the power supply cables laid vertically from the power supply units to the PSUs. Tighten cable ties by hand without too much force4) and trim the free ends. Label the cables as soon as they are laid5) and document the label text6). The illustrations in this chapter show only basic examples for the cabling between components. For more information about the cabling of the remote units, see the document Instal-

lation Manual (K-BOW Platform 2) and the installation instructions for the remote units. 1) The permissible bending radii can be found in the cable data sheets. 2) Velcro straps are less likely to deform the cables and are more flexible to handle than cable ties. 3) Coax cables from the base station to the load unit. 4) Do not use any tools to tighten the ties. This is particularly critical for fibre optic and hybrid cables. 5) See Applying Labelling, p. 42 6) See document K-BOW Numbering Scheme 936.5467 0.92 39 of 50 Cabling 7.2.2 Cabling the Fibre Optics Connections The fibre optic cables for connecting the hubs and RUs are provided. 1. Carefully insert the required SFP modules. In doing so, observe the colour labelling of the SFP modules indicated in Fig. 35. 2.

The purpose of this is to detect joints, for instance at plug connections, and damaged cables. A. Using an OTDR measurement device1), check every fibre optic lead for reflection points. If necessary, use a lead-through fibre. B. Save the measurement results in the measurement device. C. If no faults were found in step A, measure the fibre optic power2) at the ends of the fibres and record these values. D. Save the measurement results in the measurement device. E. Transfer all the measurement results into a measurement report. 1) The details for operating the measurement device can be found in the operating instructions. 2) The performance must satisfy the required minimum level of the signal. See the data sheet for the components. 7.3.2 Replacing Defective Cables within a Rack Defective cables connecting components within a rack must be replaced. This applies to all types of cable. A. Slacken the cable ties. B. Replace the defective cables. C. Tighten the cable ties. When doing this, comply with the cabling rules in the document K-BOW Cabling Guidelines. 7.3.3 Repairing Defective Cables between Parts of the Building Defective cables between buildings or between parts of a building1) must be professionally repaired and calibrated. An appropriate measurement report must be attached to the location documentation. Caution Risk of injury due to sharp edges of glass fibres. Close off the open ends of fibre optic cables with shrink sleeving, and shrink them by applying hot air. 1) e.g. hybrid cables, multi-fibre cables 936.5467 0.92 43 of 50 System Documentation 8 System Documentation It is suggested to store the system documentation in a document drawer in the main rack. The system documentation consists of the following documents:
