Replace Fan Modules for Cisco 8201 Routers

The fan module is designed to be removed and replaced while the system is operating without presenting an

electrical hazard or damage to the system. Please keep the replacement fan modules ready prior to attempting

this task.

The routers support FAN-1RU-PI (port-side intake airflow) and FAN-1RU-PE (port-side exhaust airflow)

fan modules.

Note

The airflow direction must be the same for all power supply and fan modules in the chassis.

Note

Step 1 To remove a fan module, follow these steps:

a) Press two latches on the fan module and grasp the handle of fan module.

Step 2 To install a fan module, follow these steps:

a) Hold the fan module with the LED at the top.

b) Align the fan module to the open fan tray slot in the chassis, and press the module all the way into the slot until the

left and right latches click and are locked on the chassis.

Replace Fan Modules for Cisco 8201 Routers

If the fan module does not go all the way into the slot, do not force it. Remove the fan module and verify

that it is the correct type for your router and in the correct orientation. To verify the status of fans and the

speed, use the show environment fan command.

Note

c) If the chassis is powered on, listen for the sound of the fans in operation. You should immediately hear them in

operation. If you do not hear them, ensure that the fan module is inserted completely in the chassis.

During the fan module replacement, the other fans adjust their speed to allow for proper initialization of

the new module. When you insert a new fan module, the fans may run at lower or higher speeds for a few

minutes.

Note

d) Verify that the fan module LED is green. If the LED is not green, one or more fans are faulty. If this situation occurs,

contact your customer service representative for replacement parts.

Replace Power Supply

Use this procedure to replace the AC or DC power supply units. Be sure to power down the fixed configuration

PDU (power distribution unit) before removing it from the chassis.

Step 1 If the power supply is connected to a AC or DC circuit, shut off the circuit at the circuit breaker.

Step 2 Disconnect the PSU cable.

Step 3 Press the tab inward to unlatch the PSU, and pull the handle to remove the PSU.

Step 4 Insert the new PSU.

If the PSU does not go all the way into the slot, do not force it. Remove the PSU and verify that it is the correct

type for your router and in the correct orientation.

Note

Step 5 Connect the PSU cable.

Step 6 If the power supply is connected to a DC circuit, turn on the circuit breaker for the DC power source. After replacing the

PSU, verify the power using the show environment power command.
