Removing and Installing the Chassis

The router chassis is an integrated, sheet-metal assembly that includes the upper blower module bay, the
upper card cage, the switch fabric card cage and air filter door, the lower card cage, and the lower blower

Because you are removing all the components (except the air filter) from the defective chassis and then
reinstalling them in the replacement chassis, the procedures that follow are based on these assumptions:

This approach has the advantage of protecting system components against damage by eliminating the
need to store them even temporarily outside their card cages. It also helps ensure that the physical
configuration of the router is maintained, because each transferred component is installed in the same
location in the replacement chassis that it occupied in the defective chassis.

The replacement chassis, mounted on its scissor-jack platform, is temporarily placed within reach
of the rack in which the defective chassis is installed, and is temporarily connected to the same
grounding system as the defective chassis.
A spare scissor-jack platform is available to remove the defective chassis from the equipment rack.
Components are transferred from the defective chassis to the replacement chassis.
The replacement chassis, with all the components now installed in it, is inserted into the equipment
rack in place of the defective chassis.
