The storage subsystem fan LED will indicate one of the following conditions:
v If the amber fan LED is off and the green Power LED is lit, the storage
subsystem fan is operating properly.
v If the amber fan LED is lit or the green Power LED remains off, make sure
that the storage subsystem fan is seated securely in the slot and that the
lever is snapped into place. Check the storage subsystem fan or the fan and
communications module status.
v If the storage subsystem fan LED remains on, it might indicate a problem
with the new storage subsystem fan or the fan and communications module
(both components share the same LED). Replace the storage subsystem fan
with a spare, if available. Otherwise, turn off the DS4500 Storage Subsystem
to prevent it from overheating until you can replace the fan.
