Failed Fan
What Caused the Problem?
A fan has failed and must be replaced. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Caution: Risk of Unsafe Operating Temperature. A failed fan may cause the enclosure to reach an unsafe operating temperature and shut down (you may already see an over-temperature failure being reported). Always
resolve a failed fan problem as soon as possible. There is a time limit (in the 5 to 15 minute range) beyond which you should not operate the affected enclosure with a
failed fan. This time limit depends on the model of the enclosure. Refer to the applicable hardware manual for the specific time limit.
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 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 fan may be
either located inside of a fan canister or inside of a power-fan
canister. Refer to the Component Requiring Service field in
the Details area to determine this. If the fan 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.
- Most enclosures have more than one fan. Refer to the applicable hardware manual for fan canister locations and detailed replacement procedures.
- 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.
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 removed fan canister or
the remaining 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 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. |
