CAUTION:
The power control button on the device and the power switch on the power supply do not turn off the
electrical current supplied to the device. The device also might have more than one power cord. To
remove all current from the device, ensure that all power cords are disconnected from the power
source.
CAUTION:
Never remove the cover on a power supply or any part that has the following label attached.
Hazardous voltage, current, and energy levels are present inside any component that has this label
attached. There are no serviceable parts inside these components. If you suspect a problem with one
of these parts, contact a service technician.

Identifying a failed power supply
Each power supply unit uses an LED that indicates whether the unit is working as expected. Figure 1
describes the LEDs that are displayed by the power supply units for the appliance:
The following table indicates the potential problems that can occur with the power supply and suggests
actions for you to use to correct the detected problems:
Table 1. Power supply LED combinations for detecting potential problems
AC DC Error Description Action Notes
Off Off Off No AC power is going to
the appliance, or there is a
problem with the AC
power source.
1. Check the AC power
that is going to the
appliance.
2. Make sure that the
power cord is
connected to a
functioning power
source.
3. Turn off the appliance
and then turn the
appliance back on.
4. If the problem
remains, replace the
power supply.
This condition is normal
when no AC power is
present.

AC DC Error Description Action Notes
Off Off On No AC power is going to
the appliance, or there is a
problem with the AC
power source and the
power supply detected an
internal problem.
1. Replace the power
supply.
2. Make sure that the
power cord is
connected to a
functioning power
source.
This condition occurs when
a second power supply is
providing power to the
appliance.
Off On Off The power supply is faulty. Replace the power supply. N/A
Off On On The power supply is faulty. Replace the power supply. N/A
On Off Off The power supply is not
fully seated. 1. Reseat the power
supply.
2. If a power channel
error LED on the
system board is not
illuminated, replace
the power supply.
This condition usually
indicates that a power
supply is not fully seated.
On Off or
flashing
On The power supply is faulty. Replace the power supply. N/A
On On Off The power supply is
operating normally.
N/A N/A
On On On The power supply is faulty
but it is still operational.
Replace the power supply. N/A

Replacing a failed power supply
Before you begin
When you replace a failed power supply, make sure that you do not unplug the power supply unit that
is working because this action disrupts service to the appliance.
Procedure
Complete the following steps to replace a failed power supply:
1. Remove the failed power supply from the power supply bay by pinching the side clip and pulling the
failed power supply from the bay, as shown in Figure 2.
Important: During normal operation, each power supply bay must contain either a power supply or a
power supply blank for proper cooling.
2. Slide the AC power supply into the bay until the retention latch clicks into place. Make sure that the
power supply connects firmly to the power supply connector.
3. Connect the power cord for the new AC power supply to the power cord connector on the power
supply. Figure 3 on page 6 shows the AC power supply connectors on the back of the appliance:

4. Route the power cord through the power supply handle and through any cable clamps on the back of
the appliance to prevent the power cord from being accidentally pulled out when you slide the
appliance into and out of the rack.
5. Connect the power cord to a properly grounded electrical outlet.
What to do next
Make sure that the AC power LED and the DC power LED on the AC power supply are illuminated,
which indicates that the power supply is operating correctly. The two power LEDs are to the left of the
power cord connector.
