EPLACING AN
SF/CPM
NOTE: Each SF/CPM module has two ejector levers which seats and releases the card from
the backplane connectors. During installation, the ejector levers must be positioned inward
and then rotated outward to lock into place. The ejector levers must remain in the locked
position while the card is installed in the chassis.
Figure 42: Replacing the SF/CPM Module
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 center chassis slots labelled A or B.
Holding the SF/CPM by the edges, align the card with center slot guide A or B. Slide
the card inward until the connectors are seated in the back and the faceplate is flush
with the front of the chassis.
Step 3
Simultaneously, rotate the ejector levers outward to lock the backplane connectors
and SF/CPM in place.
