7602 BCF NOTIFICATION | |||
|
Severity: |
Object affected: |
Object state: |
Module/Unit: |
|
Minor |
BCF |
Enabled |
ECxA, ESEA, ESMA, EXxA |
|
Fault reason: |
Instruction: |
Alarm cancelling: | |
|
External synchronisation signals disabled. |
1. Check the GPS antenna fix status is OK with LMUManager. Adjust the GPS antenna so that satellites become visible. 2. Check that the GPS cable is correctly mated to LMU. 3. Check that the latest LMU SW is being used. Download newer SW if necessary. 4. Replace LMU. |
Automatic. | |
|
BSS synchronisation failed. |
1. If LMU provides the synchronisation, check if alarm 8202 is active and resolve it. 2. If another BTS is the synchronisation master, check if that it is up and alive. 3. Check that the synchronisation cabling is correctly mated between the units. If LMU is used, check also Q1 cabling and power supply to the LMU unit. 4. Replace ESMA. |
Automatic. | |
|
ESMA System module cooling fan speed has reduced from the set speed. |
1. Check that nothing obstructs the fan(s) from rotating. 2. Clean the fan unit of dust and/or dirt. 3. Replace the fan unit. Note: If "Temperature high/ dangerously high" and/or 7621 alarm(s) are also active, perform these actions as soon as possible. |
Automatic. | |
|
ESMA System module temperature high. |
1. Ensure that the ambient temperature of the base station is below +50C/+122F. 2. Check if any fan alarms are also active. If active, refer to fan alarm instructions to resolve. 3. Replace the ESMA. |
Automatic. | |
|
Remote Tuned Combiner (ECxA) connected to wrong port. |
1. Connect ECxA to ESMA port 1,2 or 3 and issue a BCF reset. |
Automatic. | |
|
EXxx TRX module connected to wrong port. |
1. Connect EXxx module to ESEA. |
Automatic. | |
|
ESEA System Extension module connected to wrong port. |
1. Connect ESEA to port 6 of ESMA, and issue a BCF reset. |
Automatic. | |
|
Unknown module connected to ESxx System (Extension) module. |
1. Check the HW SW compatibility from the SW release binder a. If the module is compatible with the current SW running in the BTS, replace the module. b. If the module is not compatible with the current SW running in the BTS, check which SW version supports the module. Upgrade the BTS SW to the version that supports the module. 2. Remove the unknown module |
Automatic. | |
|
ESEA System Extension module temperature high. |
1. Ensure that the ambient temperature of the base station is below +50C/+122F. 2. If the fault persists, replace ESEA. |
Automatic. | |
|
ESMA System module unable to read internal temperature sensors |
1. Replace the ESMA. Note: If fan alarm(s) are active at ESMA, perform this action as soon as possible. | ||
