DCDU [DC-Power Distribution Unit] BBU [Base Band Unit for WiMAX]
Transmission Rack in Block-8 Should be utilized for installation unless specified otherwise. [Block 8 is the right most 60cm*60cm block when entering the shelter ] 63A fuses should be used to connect DCDU with existing DCDistribution BOX [DCDB] installed usually on wall in block 7 of the shelter. If DCDB is full then the direct connection with rectifier can be made but power team approval is required from Mobily.
DCDB uses round fuses while rectifier uses fuse with pins on top and bottom.

RRU
GPS Antenna Antenna RF Combiner
GPS should be connected to BBU through antenna arrestor. Color Coding for feeder Antenna Combiner , and CPRI for RRU BBU is extremely important to get rid of any cross connections. Swap Sites = RF Antenna azimuth for Existing [Samsung] Antennas should be noted before installation of Huawei RF antennas. Three RRU power cables should be routed in one PVC pipe. Three RRU CPRI cables should be routed in one PVC pipe. Its important to note RRU type Wimax/LTE , before installing on pole/rack.

The location requirements for installing the GPS antenna are as follows: Install the GPS antenna in open air. The installation place should have no obstacles at the angle of 10 above the horizon. Keep the antenna away from high buildings and accessory construction on the roof. Install the GPS antenna on a platform as large as possible. The antenna must have an upright visual angle greater than 90.
Note :In phase 1 we just leave this cable there because we dont insert the LTE board yet. In phase 2 we can do the connection
