SC 4812T CDMA BTS Optimization/ATP

Cannot ENABLE Device

Before a device can be enabled (placed in-service), it must be in the

OOS_RAM state (yellow) with data downloaded to the device. The color

of the device changes to green, once it is enabled.

The three states that devices can be changed to are as follows:

 Enabled (green, INS)

 Disabled (yellow, OOS_RAM)

 Reset (blue, OOS_ROM)

Follow the procedure in Table 6-6 to troubleshoot a device enable

failure.

Table 6-6: Troubleshooting Device Enable (INS) Failure

 Step Action

1 Re-seat the card and repeat the code and data load procedure.

2 If the CSM cannot be enabled, verify the CDF file has correct latitude and longitude data for cell

site location and GPS sync.

3 Ensure the primary CSM is in INS_ACT state.

NOTE

MCCs will not go INS without the CSM being INS.

4 Verify the 19.6608 MHz CSM clock; MCCs will not go INS otherwise.

5 The BBX2 should not be enabled for ATP tests.

6 If MCCs give “invalid or no system time,” verify the CSM is operable.

Miscellaneous Errors

Perform the procedure in Table 6-7 to troubleshoot miscellaneous

failures.

Table 6-7: Miscellaneous Failures

 Step Action

1 If LPAs continue to give alarms, even after cycling power at the circuit breakers, then connect an

MMI cable to the LPA and set up a Hyperterminal connection. Enter

ALARMS in the

Hyperterminal window. The resulting LMF display may provide an indication of the problem.
