Replacing a power supply module
Your server uses as many as two 520 W hot-swappable power supply modules. 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, 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, disconnect the AC 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.
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.
