Chapter 7: Installing the AT-SBx81CFC400 Controller and Ethernet Line Cards

132

Installing the Blank Slot Covers

After installing the AT-SBx81CFC400 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, “Installing the
Transceivers and Cabling the Ports” on page 135.

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 73.

Figure 73. Installing a Blank Slot Cover

2. Finger tighten the two thumbscrews to attach the blank panel to the

chassis, as shown in Figure 74 on page 133.
