Chapter 5: Installing the AT-SBx81CFC400 Control Card and Ethernet Line Cards
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.
