Chapter 4: Installing Components
Replacing a power supply module
Your server uses as many as two hot-swappable redundant power supplies. If two power
supply modules are installed and one of them 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 in this
configuration. If only one power supply module is installed, the server must be turned
off to replace it.
If you are adding a redundant power supply module to your server, you must update the
FRU/SDR after the installation is complete. For more information, see
.

This LED is not lit when the server is turned off.
AC OK LED

This LED is lit when the power supply module is

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.
Caution
Because of chassis airflow disruption, a power supply module bay
should never be empty for more than two minutes when the server
power is on. Possible damage to system components could result if
the bay is empty for more than five minutes.
If your server is configured with only one power supply module, an
active fan blank must be installed in the second power supply module
bay.
