164 Section II: Installing the Chassis
Installing the Blank Slot Covers
After installing the AT-SBx81CFC960 Controller Fabric Cards and
Ethernet line cards, check the front panel for 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 controller and line cards if the chassis is not completely
enclosed. If there are no unused slots, go to Chapter 8, “Cabling the
Ethernet Line Cards” on page 167.
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 94.
The up arrow on the panel must be pointing up.
