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

 Enabled (green, INS)

 Disabled (yellow, OOS_RAM)

 Reset (blue, OOS_ROM)

 Step Action

1 Verify T1 is disconnected from the BTS at CSU.

2 Verify LMF can communicate with the BTS device using the Status function.

3 Communication to MGLI2 must first be established before trying to talk to any

other BTS device. MGLI2 must be INS_ACT state (green).

4 Verify the card is physically present in the cage and powered-up.

5 If card LED is solid RED, it implies hardware failure. Reset card by re-seating it.

If this persists, replace card from another slot & retry.

NOTE

Primary & Redundunt CSM cards CANNOT be interchanged because only

primary CSM is equipped with a GPS receiver.

6 Re-seat card and try again.

7 If BBX2 reports a failure message and is OOS_RAM, the code load was OK.
