Chapter 6 Maintaining the Router

Removing and Installing the Chassis

Before You Begin

You will need to remove all the components except the air filter from the defective chassis and reinstall them in the replacement chassis. The recommended procedures are as follows:

•The replacement chassis is removed from its shipping packaging and placed temporarily within reach of the rack in which the defective chassis is installed, or near the surface where the defective chassis rests.

•The replacement chassis is connected to the same grounding system as the defective chassis.

•You have prepared a place to set the defective chassis when it is removed from the equipment rack or stable flat surface.

•Components are transferred from the defective chassis to the replacement chassis.

•The replacement chassis (and all the components now installed in it) is inserted into the same equipment rack or on a stable flat surface in place of the defective chassis.

This approach protects the system components—such as line cards, RPs, SFCs, CSCs, and alarm cards—from damage by eliminating the need to store them temporarily outside their card cages, bays, and slots.

Transferring components from one chassis to the other also helps to 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.

Preparing the Replacement Chassis

Move the replacement chassis near the defective chassis site. Temporarily connect the central office grounding system or interior equipment grounding system to the NEBS supplemental bonding and grounding receptacles on the replacement chassis.

For more information, see the “Supplemental Bonding and Grounding

Connections” section on page 3-9.
