Replacing a power supply module and power
board
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:
1 If 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).
2 If 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.
3 Press down on the retaining clip (1) on the power supply to release the power supply module
(2) from the chassis.
Caution
The heatsink has Thermal Interface Material (TIM) located on the bottom of
it. Use caution when you unpack the heatsink so you do not damage the TIM. If you
are reusing the original heatsink, make sure that the TIM on the bottom of the
heatsink is not damaged. If the TIM is damaged, you should apply new TIM to the
bottom of the heatsink.
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.
