4.6.3 Diagnosing MBTS Faults

In the case of GBTS/NodeB board alarms, GBTS/NodeB E1T1 alarms, and GBTS/NodeB
antenna alarms, if the causes of the fault cannot be located in the alarm information, you can
perform fault diagnosis and then take corresponding measures to handle the alarms.
Prerequisite
The automatic software commissioning already starts, and you have not confirmed the
completion of the commissioning yet.
Context
E1T1 fault diagnosis leads to the interruption of all services on the port; antenna fault diagnosis
leads to the interruption of all carrier services of the GBTS. Therefore, you need to perform the
fault diagnosis when the GBTS services are in idle state or are segregated.

CAUTION
After the fault diagnosis starts, the M2000 creates a diagnosis task and displays the
troubleshooting progress. After the fault diagnosis is complete, you can obtain the fault
diagnosis report to view fault location information.
If you delete a fault diagnosis task, the corresponding diagnosis report is deleted
accordingly. If you restart the M2000 server, all fault diagnosis tasks and reports are deleted.

or select a specific alarm of an object (board, E1/T1, or antenna) from the alarm list in the
right pane.

In the displayed dialog box, select the diagnosis type, enter the diagnosis parameters, and
then click OK. The M2000 starts the fault diagnosis.
