Replacing the power supply

Warning

The power supply in this server contains no user-serviceable parts. Only a qualified computer technician should service the power supply.

Your server comes with a 3-wire AC power cord fitted with the correct plug style for your region. If this plug does not match the connector on your surge protector, UPS, or wall outlet, do not attempt to modify the plug in any way. Use a surge protector, UPS, or wall outlet that is appropriate for the supplied AC power cord.

To replace the power supply:

1 Follow the instructions in “Preventing static electricity discharge” on page 45.

2 Follow the instructions in “Opening the server case” on page 46.

3 Lift the back of the power supply no more than ½ inch, just far enough to clear the metal tabs that hold the power supply in place.
