5 Reading Fault Status
This section describes how to use the OMT to read the fault status, using the
OMT. If any fault indicator on the RBS is on, then the fault status must be read.
1. Read the IDB, if it has not been read. See OMT User’s Manual.
2. On the Maintenance menu, click Monitor.
3. In the Monitor window, expand the Managed Object (MO) fault maps,
select RBS, then select Run.
4. Select RBS, press the right arrow, and click Start Monitor.
5. Check the RBS Event Monitor window to see if any faults are indicated
and correct them before continuing.
6. Leave the RBS Event Monitor window open for the next test.
6 Testing External Alarms
This section describes how to use the OMT to test that all external alarms, if
used, are recognized and handled correctly. The test is passed when all alarms
are recognized.
The test can be performed by shorting or leaving the corresponding pins open
on the 36-pin connector on the DXU or the 37-pin connector on the alarm cable.
Do!
Always use an approved ESD wrist strap when working with sensitive
equipment. Damage to components mounted on printed board assemblies can
occur if an ESD wrist strap is not used.
Note: The alarms must be individually identifiable in the OMT. There must be
no doubt about which alarm is indicated. The alarm message must
be unique to each alarm.
1. On the Maintenance menu, click Monitor to open the Monitor window.
