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.
