Failed or Removed Fan Canister

What Caused the Problem?

One or more fan canisters in the storage subsystem have failed or been removed. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Caution
A failed or removed 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 replace failed fan canisters 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 fan canister removed from the enclosure. This time limit depends on the model of the enclosure. To reduce the possibility of overheating, refer to the applicable hardware manual for the specific time limit.

Caution
Electrostatic discharge can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.

Important Notes

Most enclosures have more than one fan. Refer to the applicable hardware manual for fan canister locations and detailed replacement procedures.
