Replacing a Server Fan
1. Remove the top metal cover (if necessary). See “Removing the Top Metal Cover” (page 43) .
2. Grasp the replacement fan module and insert it into its fan socket.
CAUTION: If you are hot swapping a fan, replace the top metal cover within 30 minutes
to prevent damage to the server components. If the top metal cover is not replaced within
30 minutes, the server automatically shuts down.
If the server shuts down, replace the top metal cover before you restart the server.
3. Check for proper seating of the fan in its socket.
4. Replace the server top metal cover.
5. Verify the fan replacement by using the utilities identified in Appendix C (page 141) .
6. To verify fan operation, use the MP PS command
Removing and Replacing the Power Supply
The supported configuration of the server requires a minimum of one power supply unit (PSU)
to be installed. A second, optional hot-swap PSU, can be installed to provide redundant (N+1)
capability.
The power supplies in the server are hot-swappable, that is if one power supply stops working
or exhibits voltage problems, the remaining supply can support the server until the failed unit
is replaced. A power supply can be removed and replaced without turning off the server on
servers with two power supplies.
CAUTION: Before removing a power supply, make sure the second power supply is functioning
properly. The two green LEDs inside the supply must be illuminated on the second supply before
you can safely remove the failed power supply.
Removing the Power Supply
To remove the power supply:
1. Remove the front bezel from the server. See “Removing the Front Bezel” (page 45) .
