The DHCP message flow is shown in below figure. If DHCP not receive “Solicit message” from eNB then, follow the troubleshooting in next step.

Troubleshooting at eNB site To perform troubleshooting, locally at eNB side. Follow below steps

Check Connectivity between eNB and CSS (To be done locally at eNB)  Check if cable connectivity, between eNB and CSS, is working properly.  Also, check if port is up at both ends, i.e. at eNB and CSS both, if not then check with CSS team to verify proper functioning of port (shut/no-shut).  If Cable connectivity is found OK. Follow next step, with eNB engineer at the site

alarm is valid for MME Pooling configuration. When one or more MME communication fails, this alarm appears. Check the MME index for which this alarm is generated, and to resolve this problem restore the connectivity for that MME index.

Note:- Site integration and ATP11B perspective both can be carried further and this alarm can be taken for troubleshooting at later stage.

GPS Receiver Failures Normal operating GPS status should be as below. User command “RTRV-GPS-STS” from LSM-R to fetch the status.

LOCK_STATE: GPS_LOCKED HOLDOVER_STATE: GPS_NOT_HOLDOVER TOD: current date and time POS: correct value of Latitude and Longitude SAT_C: bigger than +5 TINT: less than 1.015E -05

Troubleshooting Major GPSR Alarms Check current alarms in LSM-R CLI window, by command “RTRV-ALM-LIST” GPSR ANTENNA FAIL  This alarm indicates fault related to GPSR antenna line failure.  The feeding current to the antenna is open or short level (maintained for 10 s. below 5 mA or above 120 mA) or the antenna cable is disconnected.

GPSR LOCKING FAIL  This alarm indicates that GPS receiver is not able to receive proper signals from satellite  No GPS Satellite tracking for more than 1 hour.

GPSR HOLDOVER 24H  24 hours have passed since the transition to the holdover state.

Troubleshooting Major GPSR Alarms 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.

Troubleshooting Major GPSR Alarms Check for water seepage in GPS antenna and or GPS cable.

Troubleshooting Major GPSR Alarms 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.

Troubleshooting Major GPSR Alarms 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.

Troubleshooting Major GPSR Alarms 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.

RRH Failures Check the current alarm with ‘RTRV-ALM-LIST’ on CLI command in LSM client.
