To install a SF/CPM:
Step 1 Remove the SF/CPM module from the packaging. Do not touch the printed circuit board
or connector pins.
Step 2 The SF/CPM must be installed in the lower chassis slots labeled A or B.
Hold the SF/CPM by the edges and then rotate the ejector levers inward toward the
faceplate.
Step 3 Align the card with the slot guides and slide inward until the locking mechanism engages
with the card cage.
Step 4 Simultaneously, rotate the ejector levers outward to lock the backplane connectors and
SF/CPM in place.
If an SF/CPM ejector lever does not shift to the locked position, the card is probably not
seated properly in the backplane. Pull the card out halfway and then reinsert it. Shift the
levers to the locked position.
Step 5 Secure the card in place by tightening the captive screws. The ejector levers must remain
in the locked position while the card is installed in the chassis.
