Installing a Fan Tray
If you are upgrading a fan tray, follow these guidelines:
• Remove and install fan trays one at a time.
• Perform FPD upgrade on the fan tray. Refer to the "Upgrading Field-Programmable Devices" chapter
in the
System Management Configuration Guide for Cisco ASR 9000 Series Routers
.
Note
To install a fan tray into the chassis:
Procedure
Step 1
Lift the fan tray (with two hands) and slide it halfway into the module bay.
Step 2
Slowly push the fan tray into the chassis until it mates with the backplane connector at the back of the module
bay.
To prevent damage to the connectors, do not use excessive force when inserting the fan tray into
the chassis.
Caution
Step 3
Tighten the captive screw(s) on the fan tray using the 6-inch long number 2 Phillips screwdriver to a torque
of 10 +/–1 in-lb to secure it to the chassis.
Step 4
Verify that the (green) OK status indicator on the front of the fan tray goes on. If the OK indicator does not
light, see
Troubleshooting the Cooling Subsystem
Removing and Replacing Power System Components
The Cisco ASR 9000 Series Routers support OIR of power modules. If you are replacing a redundant power
module, you can remove and install the power module while the system remains powered on without causing
an 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 power module installed (more than one for a fully configured system).
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.
For the RSP/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 remove and install AC and DC power modules used in the Cisco
ASR 9000 Series Routers.
