Input/Output Controller Replacement Instructions 27

Reconnecting Input Power and Powering Up the Router

Caution Do not align the I/O controller’s metal carrier between the slot guides. Doing so will

damage components on the I/O controller’s printed circuit board as you slide the I/O controller into

its chassis slot.

Step 6 Gently slide the I/O controller all the way into its chassis slot until you feel the connectors

make contact with the router midplane.

Step 7 Seat the I/O controller in the router midplane by tightening its captive installation screws

with a number 2 Phillips or a 3/16-inch, ﬂat-blade screwdriver.

Note The I/O controller is not fully seated in the router midplane until you tighten its

captive installation screws (use a number 2 Phillips or a 3/16-inch ﬂat-blade screwdriver).

Step 8 Connect the cables to the I/O controller’s console, auxiliary, and Fast Ethernet (if present)

ports. (For a Cisco 7200 series router, see Figure 14. For a Cisco uBR7200 series router,

see Figure 15.) (See the “I/O Controller Connection Equipment and Port Signaling”

section on page 39.)

Step 9 Replace Flash Disks or Flash memory cards (if present) in the PCMCIA slots. (See the

“Installing and Removing a Flash Memory Card” section on page 45.)

This completes the procedure for replacing the I/O controller in a Cisco 7200 series router or

Cisco uBR7200 series router.

Reconnecting Input Power and Powering Up the Router

The following procedures explain how to reconnect input power to a Cisco 7200 series router or

Cisco uBR7200 series router, power up the router, and verify a successful system boot.

Warning Read the installation instructions before you connect the system to its power source.

Reconnecting AC-Input Power

To reconnect AC-input power to a Cisco 7200 series router or Cisco uBR7200 series router,

complete the following steps:

Step 1 At the rear of the router, check that the power switch on the power supply is in the OFF

(O) position.

Step 2 Slide the cable-retention clip up (Cisco 7200 series) or to the left (Cisco uBR7200 series),

away from the AC receptacle, and plug in the power cable.

Step 3 Secure the cable in the power supply AC receptacle by sliding the cable-retention clip

down (Cisco 7200 series) or to the right (Cisco uBR7200 series), until it snaps around the

connector. The cable-retention clip provides strain relief for the AC power cable. (For a

Cisco 7200 series router, see Figure 18. For a Cisco uBR7200 series router, see

Figure 19.)
