Replacing the Input/Output Controller
Figure 31 Aligning the I/O Controller’s Printed Circuit Board between the Slot Guides in
the Cisco 7200 Series
Figure 32 Aligning the I/O Controller’s Printed Circuit Board between the Slot Guides in

Caution
Do not align the I/O controller’s metal carrier between the slot guides. Doing so will
damage components on the printed circuit board as you slide the I/O controller into its chassis slot.
Step 5 Gently push the I/O controller all the way into its chassis slot until you feel the connectors
make contact with the router midplane.
Step 6 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.
