CHAPTER 4: Installing Components

Replacing a power supply module and power board

Caution

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

Your server comes with 3-wire AC power cords 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 cords.

Your server uses as many as two 725 W hot-swappable power supply modules (optional). If your server has both power supply modules installed, the modules act as redundant, hot-swappable power supplies. If one of the two power supplies fails, the other power supply supports the server while you replace the failed power supply. You do not need to turn off the server or disconnect peripheral devices to replace a failed redundant power supply.

If your server is only equipped with a single power supply (standard), 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 down on the retaining clip (1) on the power supply to release the power supply module (2) from the chassis.

4Pull the power supply module straight out of the server with the handle. It may take considerable force to remove.

5Push the new power supply module into the server, with the retaining clip on the top, until it clicks into place.

6Reconnect the AC power cord for the new power supply module.
