1. Hold the MISP by its card-locking devices. Squeeze the tabs to unlatch the card-
locking devices and lift the tabs out and away from the card.
2. Carefully remove the MISP from its card slot, and slowly slide the card from the
module.
Installing the BRSC, SILC, and UILC
After MISPs are installed, install SILCs, UILCs, and BRSCs, as required. As the cards are
installed, keep a list of the card type (BRSC, SILC or UILC), the module number, and the
number of the card slot containing the card. Use the Core/Network Module card location form
or the IPE Module card location form at the end of this chapter to document this information.
1. Hold the card by its card-locking devices. Squeeze the tabs to unlatch the card-
locking devices and lift them away from the card.
2. Insert the BRSC, SILC, or UILC into the selected card slot of the module so it
engages the card guides in the module.
3. Slide the BRSC, SILC, or UILC into the module until it engages the backplane
connector.
4. Push the card firmly into the connector using the locking devices as levers by
pushing them toward the card's front panel.
5. Push the tabs firmly against the front panel of the card so they latch to the front lip
in the module and to the post on the card.
6. Observe the red LED located on the faceplate.
• If the red LED turns on and stays lit continuously, the card is defective. Remove
the card, choose a new card, and repeat the installation procedure.
• If it flashes three times and then turns off, the card is operating correctly. Go
to step 7.
• If the red LED flashes three times and then stays lit continuously, the card is
operating correctly but is not configured. Go to step 7.
7. On the CE or IPE Module card location form, fill in the card type and the module
number next to the slot number of the installed card.
8. Repeat steps 1 through 7 for each card requiring installation.
Remove the BRSC, SILC, and UILC
Perform the following steps to remove the BRSC, SILC, and the UILC.
1. Hold the card by its card-locking devices. Squeeze the tabs to unlatch the card-
locking devices and lift them away from the card.
2. Carefully disengage the BRSC, SILC, or UILC from the backplane connector, and
slowly slide the card from the module.
