And the Commissioning wizard is recommended to be executed prior to the hardware installation on site. The LITE system can be accessed by the Web Browser on a PC, such as Google Chrome (28.0 or higher), Firefox (26.0 or higher), IE (9.0 or higher). If Firefox or IE is to be used, Adobe Flash Player plug-in has to be installed first. (To download Adobe Flash Player, go to website http://
get.adobe.com/cn/flashplayer/.) Before logging into the LITE Web interface, the network configuration of the PC must be set as Figure 1. We suggest setting to 192.168.255.1 and subnet mask 255.255.255.248. This IP address is used to access LITE when the management PC is directly con-
nected to LITE system. By default, the private IP address of LITE is 192.168.255.3 and the subnet mask 255.255.255.248. IP address the PC FIGURE 1. PC network configuration 2.2 Commission steps 2.2.1 Logging in Steps 1. Use the Web Browser to access the private IP address of LITE. FIGURE 2.

The public management IP address and local management IP address are to be set. INFO Dont use IP address from 192.168.254.96 ~ 192.168.254.99. These 4 IP addresses are reserved for internal use. 6 LITE, R1.0, Operation and Maintenance Guide, Issue 1 FIGURE 4. Management IP Commissioning TABLE 4. Management IP Parameter Public IP Address Public IP Mask Public Gateway Private IP (Eth 1) Private IP Mask (Eth 1) Local Management IP Local Management IP Mask MAC 1 MAC 2 MAC 3 Node Type Description Public IP is used to access LITE over Management VLAN (Tagged, typically using a switch or other intranet connectivity). It is for in-band management. Private IP is used for commissioning. Local Management IP is used to access LITE locally over one of the Ethernet ports untagged, for example, from a PC running WebLCT. It is also for out-of-band man-
agement. Display the learned MAC addresses of Ethernet and Wireless ports. This field is used in chain site configuration. When it is changed to Node with P+E output, the private IP would be automatically changed to 192.168.255.4, to avoid IP address conflict in the chain site. 2.2.3 Setting the management VLAN Go to Configuration > Management > Management VLAN tab (see Figure 5).

Declaration of Conformity for RF Exposure This microwave outdoor unit product has been found to be compliant to the requirements set forth in CFR 47Section 1.1307 addressing RF Exposure from radio frequency devices as defined in Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields. Antennas with less than 23.5 dBi gain should be located at a minimum of 39.03 cm in more from the body of all persons. Calculation Formula: Pd = (Pout*G)/(4*pi*r2) Where Pd = power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 r = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1mW/cm. If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. 43 LITE, R1.0, Operation and Maintenance Guide, Issue 1 Increase the separation between the equipment and receiver. Federal Communications Commission (FCC) Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
