E.2.2

  Installing a Power Supply

You must make space for installing the power supply by removing an existing one (

Removing a Power

Supply

).

1. Remove the replacement power supply from its packaging.
2. Slide the new power supply into the empty slot.
3. Slide the new power supply into the switch until the power supply is fully seated and the release

lever snaps into place (

Removing a Power Supply

).

4. Connect the power cord to the power supply.
5. Verify the LED(s) on the power supply.

Note:  The Power Supply status LED should be a steady green for normal operation.

6. Verify the new power supply operation by issuing the  

show environment power

 command.

switch#show environment power

The output of the command lists the power supplies in operation and includes the one you replaced.

E.3

 Fan Modules

Fan module requirements when hot swapping the modules.

Note:  Hot swap fans within 30 seconds to prevent the switch from overheating. Ensure that the
module you are replacing matches those already installed in the switch.

E.3.1

 Removing a Fan Module

The following steps are required when removing or replacing fans from a switch.

Note:  Only a representative fan module is shown in 

Figure 54: Removing Fan Module 

. For the

location of the fan modules on your switch, refer to 

Rear Panel

.

1. Ground yourself with an ESD wrist strap.
2. Push the fan module release lever and slide the fan module out of the switch (

Figure 54: Removing

Fan Module 

).
