Because you will remove all of the components (except the air filter) from the
defective chassis and reinstall them in the replacement chassis, during the process
of removing the defective chassis, the procedures that follow are based on these
prerequisites:
The replacement chassis has been removed from its shipping packaging and
1.
has been 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 has been temporarily connected to the same
2.
grounding system as the defective chassis.
You have prepared a place to set the defective chassis when it is removed from
3.
the equipment rack or stable flat surface.
Components are transferred from the defective chassis to the replacement
4.
chassis.
The replacement chassis and all the components now installed in it are
5.
inserted into the same equipment rack in place of the defective chassis.
6. The replacement chassis and all the components now installed in it are placed
on a stable flat surface in place of the defective chassis.
This approach has the advantage of protecting against damage, the system
components such as line cards, RPs and CSFs by eliminating the need to store
them temporarily, outside their cages, bays and slots.
By transferring components from one chassis to the other, it will help to ensure
that the physical configuration of the Cisco 12404 router is maintained, because
each transferred component is installed in the same location in the replacement
chassis that it occupied in the defective chassis.
