Things to Know – Service Action Allowed LEDs
Each controller canister, power-fan canister, and battery canister has a Service Action Allowed LED. The Service
Action Allowed LED lets you know when you can remove a canister safely.
ATTENTION Possible loss of data access – Never remove a controller canister, a power-fan canister, or a battery
canister unless the appropriate Service Action Allowed LED is on.
If a controller canister or a power-fan canister fails and must be replaced, the Service Action Required (Fault) LED
on that canister comes on to indicate that service action is required. The Service Action Allowed LED also comes
on if it is safe to remove the canister. If data availability dependencies exist or other conditions that dictate a
canister should not be removed, the Service Action Allowed LED stays off.
The Service Action Allowed LED automatically comes on or goes off as conditions change. In most cases, the
Service Action Allowed LED comes on when the Service Action Required (Fault) LED comes on for a canister.
