Installing the DFC3 Daughter Card
Caution Use care not to damage the connectors on the module. If you damage a connector, it will be necessary
to return the module to Cisco for repair.
Step 6 Position the installation bracket over the two male standoffs at the back of the DFC daughter card. Apply
pressure to the top of the bracket, as shown in Figure 18 to fully seat the DFC3 daughter card on the
module.
Caution When seating the DFC daughter card, do not apply pressure to any other location on the DFC daughter
card, especially the heat sinks.

Step 7
Use a Phillips-head screwdriver to install the securing screws and the two cap nuts. (See Figure 19.)
Caution Yo u must install screws in all available standoffs. The screws provide grounding between the DFC3
daughter card and the module. Failure to install all of the screws will invalidate the safety approvals and
pose a risk of fire and electrical hazard.
