Removing and Replacing FRUs

This chapter describes procedures for removing and replacing field-replaceable units (FRUs) from Cisco Catalyst 9800-40 Wireless Controller.

Removing AC Power Supplies

Procedure

Step 1

Ensure that the chassis power switch is in the Standby position.

It is not required to place the chassis power switch in the Standby position, if you want to hot-swap a single power supply.

Step 2

Unplug the power cable from the power supply.

Step 3

Press the retaining latch toward the pull handle.

Grasp the handle with one hand, and pull the power supply out of the slot while supporting the weight of the power supply with the other hand.

Step 4

Repeat step 1 to step 3, to remove the other AC power supply.

Installing AC Power Supplies

Ensure that the chassis power switch on the chassis is in the Standby position.

It is not required to place the chassis power switch in the Standby position, if you want to hot-swap a single power supply.

Step 2

Removing and Replacing USB Flash Memory Stick

The Cisco Catalyst 9800-40 Wireless Controller contains the USB ports for a flash memory stick to store configurations or Cisco IOS XE consolidated packages.

Caution
Do not remove a USB flash memory stick when issuing a file access command or a read/write operation to the flash memory stick when it is processing. The controller might reload or the USB flash memory stick may get damaged. Before removing the USB device, check to see if the USB activity LED on the front panel is flashing.

To remove and then replace a USB flash memory stick, follow these steps:

Procedure

Step 1

Pull the flash memory stick from the USB port.

Step 2

To replace a Cisco USB flash memory stick, insert the module into USB port 0 or 1.

The flash memory stick can be inserted only in one way, and can be inserted or removed regardless of whether the controller is powered up or not.

Repacking the Controller

If your system is damaged, you must repack it for return shipment.

Before you return the controller or move it to a different location, repack the system using the original packaging material.
