26 Input/Output Controller Replacement Instructions
Removing and Replacing the Input/Output Controller
Step 4 Using both hands, grasp the I/O controller by its metal carrier edges and orient the I/O
controller so that its printed circuit board components are upward. (See Figure 7.)
Caution Handle the I/O controller by the carrier edges and handle only; never touch the printed
circuit board components or connector pins.
Step 5 Align the left and right edge of the I/O controller’s printed circuit board between the I/O
controller slot guides. (For a Cisco 7200 series router, see Figure 16. For a
Cisco uBR7200 series router, see Figure 17.)
