Card Replacement Process
Removing the I/O End Cap
To remove the I/O end cap, follow these steps:
Step 1 Using a 3/8-inch socket wrench to loosen the four 1/4-20 bolts on the end cap.
Note If a protective end cap cover (see Figure 2-16) is used to provide weatherproof protection for the
ports on the I/O end cap, loosening the four 1/4-20 mounting bo lts on the protective end cap
allows you to remove the protective end cap and the I/O end cap from the extrusion.
Step 2 Carefully remove the I/O end cap and pull the end cap I/O cable out from under the card stack to free
the end cap (see Figure 2-4).
