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
chassis must be completely enclosed for the fan module to maintain
adequate airflow across the control and line cards. If there are no unused
slots, go to Chapter 6, “Installing the Transceivers and Cabling the Ports”
on page 131.
To install the blank panels on the unused slots, perform the following
procedure:
1. Position a blank slot cover over an unused slot. In Figure 83 a blank
slot cover is being installed over slot 2.
