Alarm/Redundancy Tests

Follow the steps in Table 3-48 to verify alarms reported by the master

GLI are displayed via the alarm monitor if a BTS frame module failure

occurs.

Table 3-48: Miscellaneous Alarm Tests

Step Action

1 Select Util>Alarm Monitor to display the alarm monitor window.

2 Perform the following to verify fan module alarms:

• Unseat a fan module (see Figure 3-21 or Figure 3-22).

• Observe an alarm message was reported via the MGLI (as displayed on the alarm monitor).

• Replace fan module and verify the alarm monitor reports that the alarm clears.

• Repeat for all other fan modules in the BTS frame.

NOTE

Follow Step 3 for Starter Frames and Step 4 for Expansion Frames.

3 Starter Frames Only:

Perform the following to verify MPC module alarms.

• Unseat MPC modules (see Figure 3-19) one at a time.

• Observe that an alarm message was reported via the MGLI as displayed on the alarm monitor.

• Replace the MPC modules and verify the alarm monitor reports the alarm clears.

4 Expansion Frames Only:

Perform the following to verify EMPC module alarms.

• Unseat EMPC modules (see Figure 3-19) one at a time

• Observe that an alarm message was reported via the MGLI as displayed on the alarm monitor.

• Replace the EMPC modules and verify the alarm monitor reports that the alarm clears.

5 If equipped with AMR redundancy, perform the following to verify AMR module redundancy/alarms.

• Unseat AMR 2 (see Figure 3-19).

• Observe that an alarm message is reported via the MGLI (as displayed on the alarm monitor).

• Repeat Steps 1 through 3 and/or 4.

• Replace the AMR module and verify the alarm monitor reports that the alarm clears.

• Unseat AMR 1 and observe an alarm message was reported via the MGLI (as displayed on the alarm

monitor).

• Replace the AMR module and verify the LMF reports the alarm has cleared.

NOTE

All PWR/ALM LEDs should be GREEN at the completion of this test.
