Replacing a power supply module
Your server uses as many as three 700 W hot-swappable power supply modules. If your server
has more than one power supply module installed, the modules act as redundant, hot-swappable
power supplies. If one of the power supply modules fails, the other power supply module(s)
support the server while you replace the failed module. You do not need to turn off the server
or disconnect peripheral devices to replace a failed redundant power supply module.
If your server is only equipped with a single power supply module, the server must be turned
off and the AC power cord removed before replacing the module.
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 or more power supply modules installed, you do not need to turn
off the power to the server before continuing.
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 remove the old
TIM, then 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.
