Table 5-6: Troubleshooting Device Enable (INS) Failure

 Step Action

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

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

data for cell site location and GPS sync.

3 Ensure primary CSM is in INS_ACT state.

NOTE

MCCs will not go INS without the CSM and the BDC being INS.

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

5 The BBX should not be enabled for ATP tests.

6 If MCCs give “invalid or no system time,” verify the BDC is enabled. If error

persists, verify the CSM is enabled.

 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.

ALARMS in the Hyperterminal window. The resulting LMF display may

provide an indication of the problem. (Call Field Support for further assistance.)
