RJIL Plan

However, some case even GBM/GBT/RTT(Delta)

sites may not be found the TGB, then RRU-V2

ground cable has to be connected to OGB

directly.

If, different site condition compare to RFI report

about TGB existence, SOLPAR should report to

Samsung . This case may not be able to install

the ground cable due to cable shortage.

→ In case of no TGB on the pole or

Case#2) Connection with TGB

Case#1)

Case#2)

When connecting ground cables to the system ground terminal, the pressure terminals of RRU-V2

ground cable and CPRI ground cable should be in a reversed configuration of ‘Y’.

At this time, the CPRI ground cable should be located inners side. If it is not, the RRU-V2 ground cable

and CPRI ground cable are installed crossing each other.

Troubleshooting Action:

Check the GPS status in LSM-R CLI window with command “RTRV-GPS-STS”, to check current status of GPS.

Check the GPSR antenna cables installation and cable connection assembly.

Check for any damage/break of GPSR cables. The GPS antenna cable, like all RF cables, should never pulled on, crushed by an over tight strap (cable tie) or stapled. Damaging the cable could result in inconsistent readings over the time, and occasional loss of GPS lock. So check GPS Cable for such tight strap or damages, if found, replace that cable.

Check for water seepage in GPS antenna and or GPS cable.

Check GPSR antenna for any physical damage, if any, replace GPSR antenna.

Check the voltage by multi meter at the Antenna end connector (it should be ~ 5V) & Arrestor (at end side) (it should be around ~5.15V). If there is major difference between the reading, need to correct the connectotization.

Check the location where GPSR antenna is installed. For proper tracking of GPS satellite GPS antenna must be installed at such location

Location that has a clear, unobstructed view of the sky in all directions.

Should be installed on Top of Tower.

There should be minimum distance of 1m between GPSR antenna and other radio antenna installed.

It should not be installed below or back side of Microwave antenna.

Reset the board (UAMA).

Replace the GPS antenna.

Replace the board (UAMA), if still alarm remains (even after checking GPS assembly installation and replacing GPS cables & GPSR antenna).

If still issue remains, contact Samsung NEO team.
