Drive carrier module faults
Each Drive Carrier module has two LEDs: an upper (green) LED and a lower (amber) LED.
vUnder normal operation, the green LED is on and will flicker as the drive operates
vUnder normal operation, the amber LED will be:
–Off if there is no drive present
–Off as the drive operates
–On if a drive fault is present
Dealing with hardware faults
Ensure that you have obtained a replacement module of the same type before removing any faulty module.
vIf the subsystem is powered up and you remove any module, replace it immediately. If the subsystem is used with modules or module blanks missing for more than a few minutes, the enclosure can overheat, causing power failure and data loss. Such use will invalidate the warranty.
vReplace a faulty drive with a drive of the same type and equal or greater capacity.
vRefer to your
vAll drive bays must be installed with a drive carrier module in order to maintain a balanced airflow.
