Chapter5 Replacing Cisco ASR 9000 Series Router Components
Removing and Replacing Power System Components
Caution Use two hands when handling the fan tray. Each CiscoASR 9010 Router version 1 fan tray weighs about
16 pounds (7.27kg). Each Cisco ASR 9922 Router fan tray or Cisco ASR 9010 Router version 2 fan
tray weighs about 18pounds (8.18 kg).
To install a fan tray into the chassis:
Step1 Lift the fan tray (with two hands) and slide it halfway into the module bay.
Step2 Slowly push the fan tray into the chassis until it mates with the backplane connector at the back of the
module bay.
Caution To prevent damage to the connectors, do not use excessive force when inserting the fan tray into the
chassis.
Step3 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.
Step4 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, page4-32.
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.
Note 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.
