keep the cutting section away from dust or foreign material. If the cable is soiled with foreign

material, do not blow to remove them. Make sure to clean the connector in accordance with the

cleaning directions for the optic cable. Refer the ‘ANNEX D’.

3) Do not touch the ferrule (white colored part) at the end of optic connector, because the ferrule can

Check the MCB status ON/OFF

Check MCB, for DU unit and RRH units at DCDB end

Turn on the eNB by flipping the breaker on the power supply

If Still No Power, Check the Power cable connectivity at DU side

Page 172: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

Check the Power cable connectivity at DU side

Check the Power cable assembly at DU unit, for proper connections, as per figure below

Check the other end of power cable assembly is connected properly to the MCB placed in SMPS/DCDB panel, according to polarity

Page 173: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

Dismount/Mount UAMA board (to be done at field)

Power OFF, DU unit MCB from DCDB

Disconnect the cable connected to UAMA carefully ‘1’

Check the original cable connection before disconnecting the cables to make sure the cables are re-connected correctly after UAMA is replaced

Unscrew the two captive screws with a hand or Philips torque driver

Turn the levers on the both sides on the board

Hold the both levers, and then carefully pull the UAMA out of the board without causing any disturbance to nearby boards

Page 174: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

Dismount/Mount UAMA board (to be done at field)

Now carefully push in to the board along the guideline

Tighten the two captive screws at the front side of UAMA with a hand or a Philips torque driver.

Re-connect the cables which were disconnected in the step ‘1.’

Check LED status (On) to see whether the UAMA is running successfully.

If LED still not glowing then suspected UAMA board faulty. Replace UAMA.

eNB to DHCP Connectivity Issues Check with DHCP team, if DHCP configuration for that eNB site is done or not DHCP Configuration is done or not

RS_IP for that eNB is configured as per ODD

If eNB OAM plane IP address is configured in DHCP for that eNB or not

Connectivity between DHCP and CSS is established or not

Escalate to RJIL Team for any correction in above steps

If DHCP is able to receive/send any DHCPv6 message with eNB. The DHCP message flow is shown in below figure. If DHCP not receive “Solicit message” from eNB then, follow the troubleshooting in next step.

Page 176: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

Troubleshooting at eNB site

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

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

eNB environment parameter setting (check by on field eNB engineer)

Login eNB site locally with root login, and check eNB environment parameters by command “getenv –a”, for PnP grow configuration DEFAULT_VLANID=103

BOOTMODE=dhcp

IPV6_ENABLE=1

DEFAULT_IPVER=64

Connectivity check between LSM to CSS

Login to LSM-R CLI window and check whether eNB_GW (CSS) IPv6 address is reachable from LSM-R using ping6 command as shown in below figure, Where “DST_IP_ADDR” will be eNB GW IP and “SRC_IP_ADDR” is LSM IP

After getting IPv6 address and RS_IP address, If still eNB is not able to communicate with LSMR then follow below steps.

Troubleshooting from LSM-R

If the eNB is still not reachable then escalate to RJIL data team

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.

Page 187: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

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.

Page 188: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

Troubleshooting Major GPSR Alarms

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

Page 189: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

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.

Page 190: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

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.

Page 191: EnodeB MaintenanceTraining for RJIL FEOs V2.0.pdf

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.
