Installing the Blank Slot Covers
After installing the AT-SBx81CFC400 Controller Fabric Cards and
Ethernet line cards, check the front panel for any unused slots and cover
them with the blank slot covers included with the chassis, as explained in
this procedure. The fan module may not be able to maintain adequate
airflow across the control and line cards if the chassis is not completely
enclosed. If there are no unused slots, go to Chapter 6, “Installing the
Transceivers and Cabling the Ports” on page 123.
To install the blank panels on the unused slots, perform the following
procedure:
1. Position a blank slot cover over an unused slot, as shown in Figure 76.

2. Finger tighten the two thumbscrews to attach the blank panel to the
chassis, as shown in Figure 77 on page 121.
