Failed Power Supply
What Caused the Problem?
A power supply has failed and must be replaced. The Recovery Guru
Details area provides specific information you will need as you follow
the Recovery Steps.
Caution:
Possible loss of data accessibility. Do not remove a
component when either (1) the Service action (removal) allowed
(SAA) field in the Details area of this recovery procedure is NO (
),
or (2) the SAA LED on the affected component is OFF (note that some
products do not have SAA LEDs). Removing a component while its SAA LED
is OFF may result in temporary loss of access to your data. Refer to the
following Important Notes and the Recovery Steps for more detail.
Caution:
Electrostatic discharge can
damage sensitive components.
Always use proper antistatic protection when handling
components. Touching components without using a proper ground may damage
the equipment.
Important Notes
- Depending on the model of your storage subsystem, the power supply
may be either directly accessible or located inside of a power-fan
canister. Refer to the Component Requiring Service field in
the Details area to determine this. If the power supply is
located inside a power-fan canister, then be aware that removing a
power-fan canister affects the cooling of the storage subsystem in
addition to the supply of power to the storage subsystem.
- Because of this failure, the storage subsystem currently does not
have redundant power supplies. The storage subsystem will continue to
operate with the remaining power supply. However, failure of the
remaining power supply will result in a loss of access to the
storage subsystem. Therefore, make sure you correct this problem as soon
as possible.
- Service Action Allowed Important Information:
- The Service action (removal) allowed field in the
Details area indicates whether or not you can safely remove
the component. If the SAA field is NO (
),
then the affected component must remain in place until you
service another component first.
- The Service action LED on Component field in the
Details area indicates whether or not a physical SAA LED is
present on the hardware component. This field does NOT
indicate whether the LED is ON or OFF (that indication is
provided by the Service action (removal) allowed field).
- If a component does not have an SAA LED, then it is OK
to remove the component when its fault LED is lit and the
Service action (removal) allowed field = YES (
)
in the Details area.
- The Service action (removal) allowed field shown
in the Details area and the physical SAA LED on the hardware
component (if supported) MUST match before you remove the
affected component. In rare cases (such as multiple
problems), the status of the LED and the SAA field may not
match. If there is a mismatch, then you should NOT remove
the component until these indications match. The Recovery
Steps will help you to make this determination.
Recovery Steps
1 |
Check the Service Action Allowed status for the
Component Requiring Service in the Details area.
If... |
Then... |
Service Action Allowed
= YES ( ) |
Check the Service action LED on
Component field in the Details area and then
answer the following question:
Does the field indicate that this
component has a physical SAA LED?
- Yes - Check the physical component to
ensure the LED is ON.
- If the LED is ON, then go to
step 2.
- If the LED is OFF, then click
the Recheck button to see if
another problem appears in the
Summary area.
- If there is another
problem, fix it first and
then return to this
procedure.
- If there is no other
problem, then stop this
procedure and contact your
technical support
representative.
- No - Go to step 2.
|
Service Action Allowed
= NO ( ) |
Answer the following question:
Are there other problems being reported in
the Summary area?
- Yes - Fix these problems first and
then return to this procedure after clicking the
Recheck button.
- No - stop this procedure and contact
your technical support representative.

|
2 |
Remove the component listed in the Component
Requiring Service field in the Details area. |
3 |
Check the model of the remaining power supply
or power-fan canister and ensure that the new canister is the
same model. If you do not have a replacement that is the same
model, contact your technical support representative. |
4 |
Insert the new power supply or power-fan
canister securely into place. |
5 |
Click the Recheck button to rerun the
Recovery Guru. The failure should no longer appear in the
Summary area. If the failure appears again, contact your
technical support representative. |
