CHAPTER 4: Installing Components
If your server is only equipped with a single power supply, the server must be turned off and the AC power cord removed before replacing it.
To replace a power supply module:
1If your server is equipped with more than one power supply module, determine which power supply module has failed (the LED on the power supply will be orange).
2If your server has only one power supply module installed, make sure that you turn off the server, then unplug the power cord before continuing.
- OR -
If your server has two power supply modules installed, you do not need to turn off the power to the server before continuing.
3Press the retaining clip on the power supply to the left to release the power supply module from the chassis.
4Pull the power supply module straight out of the server with the handle. It may take considerable force to remove.
5Insert the new power supply module into the server, with the retaining clip on the right, until it locks into place.
6Reconnect the AC power cord for the new power supply module.
