Cannot ENABLE Device

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

OOS_RAM state (yellow in LMF display) with data downloaded to the

device. The color of the device on the LMF changes to green once it is

enabled.

The four device states that can be displayed by the LMF are:

S Enabled (bright green, INS_ACT)

S Stand–by (olive green, INS_SBY – redundant CSM and GLI only)

S Disabled (yellow, OOS_RAM)

S Reset (blue, OOS_ROM)

Table 6-9: Troubleshooting Device Enable (INS) Failure

n Step Action

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

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

location and GPS sync.

3 Ensure primary CSM is in INS_ACT (bright green) state.

NOTE

MCCs will not enable without the CSM being INS.

4 Verify 19.6608 MHz CSM clock is present; MCCs will not enable without it.

5 BBXs should not be enabled for ATP tests.

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

7 Log out of the BTS, exit the LMF, restart the application, log into the BTS, and re–attempt

device–enable actions.
