To remove and replace the fan tray:

Removing and Replacing Power Supply Units

WARNING: Do not remove a panel blank unless you are ready to install a power supply into that slot. After

removing a power supply, immediately place a panel blank in the empty slot. Blanks are required to control

airflow and electromagnetic interference.

CAUTION: Do not install the Power Supply 1200W-AC and Power Supply 1600W-AC in the same chassis.

The line cards will power down and data may be lost.

A power supply failure is recognized by a red LED, a lit RPM alarm LED, and, if configured, an SNMP

trap. If you are operating your C300 chassis with a redundant power supply, you can install, remove, or

replace a power supply without affecting system operation. If you are operating your C300 system with

only two

power supplies (the minimum), you must completely turn off the system to replace a power

supply.

NOTE: If a power supply fails, the entire unit must be replaced. There are no field serviceable parts inside the

unit.

Step Task

1 Unscrew the retaining screws at the top and bottom of the fan tray.

2 Use the handle to pull the fan tray out approximately two inches from the chassis. Wait 30 seconds, until the fan

blades stop rotating, then completely remove the fan tray.

3 Insert the new fan tray into the chassis. Guide the tray firmly into the slot until it stops and the handle end is

flush with the chassis.

4 Secure the fan tray into place by tightening the screws at the top and bottom of the fan tray using a #2 Phillips

screwdriver.
