Chapter 3 Replacing Cards in the Cisco ISR 3270 Rugged Enclosure

Card Replacement Process

Removing the I/O End Cap

To remove the I/O end cap, follow these steps:

Step 1 Use a 3/8-inch socket wrench to loosen the four 1/4-20 bolts on the end cap using a torque range of 58 to 68 in-lb.

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 bolts 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 pull off the end cap enough to give you enough room to disconnect the power cable. Figure 3-3shows the cables.

	card stack when you removed the antenna end cap) from beneath the card stack to free up the I/O end cap.
Step 5	Place the end cap on your work surface.
