Removing and Installing a Chassis
Removing and Installing a Chassis
This section provides the procedures to remove and replace a chassis. You may
need to perform this procedure to replace a defective chassis or move it to another
location. These instructions include the steps directing you to removal and
replacement instructions for individual components such as power supplies and
line cards.
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 the following prerequisites:
•
The replacement chassis, mounted on its own 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 with the anchor clips and bolts (that came with
the original chassis) is available to remove the defective chassis from the
equipment rack.
•
Components are transferred from the defective chassis directly to the
replacement chassis.
•
The replacement chassis is installed in the equipment rack after all
components are installed.
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.
