Closing the Chassis

Testing ROM Installation

Tip Before testing your ROM installation, close the router chassis using the procedure provided in the

“Closing the Chassis” section on page 19.

Test your installation by rebooting the router. If you installed the ROM correctly, the router boots into

the ROM monitor or operating system.

If you suspect that the ROM is inserted incorrectly, remove and reinstall the ROM as described in the

“Replacing the Boot ROM in Cisco 2600 Series Routers” section on page 15. Reboot the router again.

Closing the Chassis

This section describes the procedure for closing the chassis.

Installing the Chassis Cover on Cisco 261x, Cisco 262x, Cisco 265x, and

Cisco 26xxXM

To close the chassis:

Step 1 Referring to Figure 1 and Figure 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 2 When the two sections fit together snugly, slide the chassis top so it fits into the front bezel.

Step 3 Replace the cover screws. Tighten the screws to no more than 8 or 9 inch/pound of torque.

Step 4 Reinstall the chassis on the wall, rack, desktop, or table.

Step 5 Reconnect all cables. If the router uses a DC power supply, switch the circuit breaker to the ON position.

Installing the Chassis Cover on Cisco 2691

Step 1 Hold the cover so the tabs at the rear of the cover are aligned with the chassis.

Step 2 Push the cover toward the rear, making sure that the cover tabs fit under the chassis back panel, and the

back panel tabs fit under the cover.

Step 3 Slide the cover slightly to the left to lock the cover into position. (See part 1 in Figure 16.)
