Replacing a power supply module
If your server uses the optional hot-swappable, redundant power supplies and one of the
two power supplies fails, the other power supply module supports 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 power supply module.
To replace a power supply module:
1
If you only have one power supply module, turn off your server.
2
If you have two power supply modules, examine the LED indicators on the back of
each power supply module to identify the failed module. The power supply module
has failed if the orange (right) LED indicator is on.
3
Unplug the power cord from the failed power supply module.
Warning
The power supply modules in this server contain no user-serviceable
parts. Only a qualified computer technician should service the power
supply modules.
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 UPS or wall outlet that is appropriate for
the supplied AC power cords.
