Installing the Blank Slot Covers
After installing the AT-SBx31CFC Control 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 127.
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 81.

chassis, as shown in Figure 82 on page 125.
