Replacing a Line Module
Step 3 Before removing a LM-BCC, make sure the standby BCC stby indicator is on steady. A flashing stby
indicator indicates it is in the process of downloading either configuration data or software and is not
ready to accept a transfer.
Step 4 For a single card configuration, disconnect the cables from the back card face plate. Make a note of the
location of each cable so that it can be replaced correctly.
Step 5 For a redundant card configuration, disconnect the appropriate leg of the Y-cable connecting to the back
card to be replaced. DO NOT REMOVE THE OTHER LEG GOING TO THE BACKUP CARD.
Step 6 Loosen the two captive screws on the back card faceplate and, pulling on the top and bottom card
extractors, slide the card straight out of the shelf slot. (See Figure 30-2.)
To install a line module:
Step 1 Insert the line module (such as, LM-3T3) into the slot from which the defective card was removed (see
Figure 30-2).
Step 2 Tighten the two captive screws. Tighten securely, but do not overtighten.
Reconnect the T3 trunk cables to the LM-3T3 connectors from which they were disconnected.
Step 3
Step 4 Perform the appropriate steps to bring the lines that were disconnected back on line.
