Installing an I/O Card in the Cisco ASA 5545-X and 5555-X Chassis
To replace an I/O card in an ASA 5545-X or 5555-X chassis, follow these steps.
Detailed Steps
Step 1 Power off the chassis, remove the power cable from the chassis, and remove the chassis from the rack.
Step 2 Locate a grounding strap, and fasten it to your wrist so that it contacts bare skin. Attach the other end to
the chassis. See the “Working in an ESD Environment” section on page 2-3 for more information.
Step 3 With your fingers, loosen the captive installation screw on the rear of the chassis.
Step 4 Remove the chassis cover by placing your hand on top of the chassis lid, pressing down firmly, and
pushing the cover toward the rear of the chassis.
Step 5 Determine the location of the I/O card. (See Figure 4-8.)
