Step 1Connect the power cord.
Step 2 Connect the Ethernet cables.
Step 3 Connect any other required cables.
Step 4 Loop and secure the power cable(s) using
the retension strap as show on the right.
Proceed to Section 10, Securing the Cables to the Rack
on page 9.
There is a Power Good LED
on each power supply module
located under the handle to
indicate power supply status.
The LED operation is defined
in the table below.

Power Supply Indicator LED
Description
A valid power source is connected to the PSU and the PSU is
operational.
Indicates a problem with the PSU.
Power is not connected to the PSU.
When the firmware of the PSU is being updated, the PSU handle
blinks green.
When hot-plugging a PSU, the PSU handle blinks green five times
at a rate of 4 Hz and turns off. This indicates a PSU mismatch with
respect to efficiency, feature set, health status, or supported voltage.

CAUTIONS
nDo not disconnect the power cord or unplug the
PSU when updating firmware. If firmware update
is interrupted, the PSUs do not function.
nIf two PSUs are installed, both the PSUs must have
the same type of label; for example, Extended
Power Performance (EPP) label. Installing different
PSUs is not supported, even if the PSUs have the
same power rating. This results in a PSU mismatch
condition or failure to turn the system on.
nWhen correcting a PSU mismatch, replace only the
PSU with the blinking indicator. Swapping the PSU
to make a matched pair can result in an error condition
and unexpected system shutdown. To change from a
high output configuration to a low output configuration
or vice versa, you must turn off the system.
n
AC PSUs support both 240V and 120V input voltages
with the exception of Titanium PSUs, which
support only240V. When two identical PSUs receive
different input voltages, they can output different
wattages, and trigger a mismatch.
nIf two PSUs are used, they must be of the same type
and have the same maximum output power.
nCombining AC and DC PSUs is not supported and
triggers a mismatch.
