Replace Chassis Components
Since the Fan trays are blocking the view, Fabric card LEDs might not be visible. Therefore, you can verify
the Fabric card LEDs status using show led location 0/FClocation command.

Replace Power Supply Components

The Cisco 8800 series routers support OIR of power modules. If you are replacing a redundant power module,
you can replace the power module while the system remains powered on without any electrical hazard or
damage to the system. This feature enables you to replace a power module while the system maintains all
routing information and ensures session preservation.
However, to maintain operational redundancy and proper cooling, and to meet EMI compliance standards,
you must have at least one working redundant power module that is installed. When you remove a failed
power module with the router in operation, perform the replacement as quickly as possible. Make sure you
have the replacement power module ready before beginning the removal and installation procedure.
Note
For the RP to communicate properly to a power module in a power tray, input power to at least one of the
power modules in the power tray should be present.
This section contains procedures on how to replace the power modules.
Caution
Do not turn off the switch on the power tray to remove individual power modules. Power modules support
OIR, so they can be removed and replaced with the power on and the system operating.
