Closing the Chassis
This section describes the procedure for closing the chassis.
Replacing the Chassis Cover on Cisco 261x, Cisco 262x, Cisco 265x, and
Cisco 26xxXM
To close the chassis:
Step 1 Position the two chassis sections, as shown in Figure B-2.
Step 2 Referring to Figure B-2, press the two chassis sections together and verify the following:
• The top section fits into the rear of the bottom section. The bottom section fits into the front of the
top section.
• Each side of the top and bottom sections fits together.
Caution To fit the two sections together, it might be necessary to work them together at one end and then the
other, working back and forth; however, use care to prevent bending the chassis edges.
Step 3 When the two sections fit together snugly, slide the chassis top so it fits into the front bezel.
Step 4 Replace the cover screws. Tighten the screws to no more than 8 or 9 inch/pound of torque.
