Result: /c nok, /d ok
This alarm is raised if there is a hardware fault in a support system unit. The
alarm indicates that the unit must be replaced, there is an unrecoverable
hardware fault
Autonegotiation Failed to Meet Minimum Requirements
This Alarm will impacting Services if both SyncReference
(Synchronization=1,PacketFrequencySyncRef=1 &
Synchronization=1,PacketFrequencySyncRef=2) having "Loss of Tracking". This
quite related to transport bandwidth which also simillar symptom impcating

Timeout when trying to access radio. (This alarm will raised the secondary
alarm: "Service Degraded").
YES
The alarm is raised when the measured RF reflected power in the radio unit
exceeds a predefined threshold. (This alarm will raised the secondary alarm:
"Service Degraded").
NO

Method of troubleshoot (Combination between Experienced & Alex/CPI)
Check the transport part
If transport part OK, check VLAN IP OAM
If all above ok, Check on site and troubleshoot on the physical hardaware / connection,
Clear the primary alarm, this alarm will be ceased
Refer to CPI as attached:
Check Fan Unit at site
Cold Restart DUS (if the alarm remain, change DUS)
1.Identify and restart the faulty board or unit. See Restart Board for instructions.
2.Check that the alarm has ceased.
3.If the alarm remains, identify and lock the faulty board or unit. See Lock Board for instructions.
4.Replace the faulty board or unit.
See Replacing Alarm Units, Replacing Control Units, Replacing Power Units or Replacing EMU for
instructions.
5.Unlock the board or unit. See Unlock Board for instructions
configuredSpeedDuplex must be equal/match with actualSpeedDuplex
Try to reset "Loss of Tracking" on impacted
TransportNetwork=1,Synchronization=1,PacketFrequencySyncRef
"get ntp", check the Ntp Server Ip Address. For LTE Phase-1 and Phase-2, the Server-1 IP is
(10.200.170.116) & Server-2 IP is (10.203.178.165). If wrong IP, do change the IP address. Alarm will be
ceased. In normal condition, ,NtpServer=1 service status is "6 (SYSPEER)" and NtpServer=2 service
status is "4 (CANDIDATE)". Or Either one NtpServer service status is "6 (SYSPEER)".
Need to check on site. Check on EPC Bus cable to SAU, SCU, PDU
Check both IP adressed of PTP Server are correct (follow ATND). If all IP and VLAN address are correct,
need to check on Transport (PDH, SDH, ME, PE Router) and NTP Server it self (Hardware/Software)
Clear the primary alarm, this alarm will be ceased
Clear the primary alarm, this alarm will be ceased
Warm Restart DUS and if not cease, check transport bandwidth bottle neck
Check both IP adressed of PTP Server are correct (follow ATND). If all IP and VLAN address are correct,
need to check on Transport (PDH, SDH, ME, PE Router) and NTP Server it self (Hardware/Software)
1.Check if the SCU is equipped with an external temperature sensor.
a.If it is, replace the external temperature sensor as instructed in Replacing Fans and Climate Units, and
then restart the SCU as instructed in Restart Board.
b.If it is not, replace the SCU as instructed in Replacing Control Units.
2.Check that the alarm has ceased
Delete the corrupted upgrade package (make sure not the current UP)
LOCKED Impacted Cell for 8 seconds and UNLCOKED it
Restart impacted RRU/RU or DUS Warm Restart
Instal complete LKF / inject optional required LKF. Always check "st cell & ue print -admitted"
Tunnelling Issue in ME Transport
Restart RRU, check "st cell", if still not up, check "cabx", can see normally RRU faulty
Check configuration, cabx and probably need to check on site on the RiLink connection between DUS RRU
Restart impacted RRU/RU. If "No connection with
ManagedElement=1,Equipment=1,AuxPlugInUnit=RRU-1", then need to check on site on the
RiLInk/SFP's connection between DUS-RRU
Related to "Heartbeat Failure", need to check RU & DU power at site
Check on MME IP Service, S1_MME Vlan. All good, its more towards Transport issue (SCTP)
Clear the primary alarm, this alarm will be ceased
Restart impacted RRU
Need to check on site, due to problems in the antenna cable or in the RF connector
set Equipment=1,Cabinet=1 productData, or if product data not available, copy from 3G product data
Restart impacted RRU/RU. If "No connection with
ManagedElement=1,Equipment=1,AuxPlugInUnit=RRU-1", then need to check on site on the
RiLInk/SFP's connection between DUS-RRU
Possible SFP module malfunction which can lead to reduced bit rate, erroneous data, or laser failure.
Check on-site
