16 Input/Output Controller Replacement Instructions
Installation Prerequisites
Caution Make sure to tighten the captive installation screws on the network processing engine,
Cisco uBR7200 series cable modem cards, and the I/O controller (use a number 2 Phillips or a
3/16-inch, flat-blade screwdriver). These screws prevent accidental removal, provide proper
grounding for the router, and help to ensure that the network processing engine, Cisco uBR7200
series cable modem cards, and the I/O controller are properly seated in the router midplane.
