3.3Starting the Drives
Unless otherwise selected during installation, all drives in the enclosure should automatically start their motors. If this has not occurred one of the following conditions may exist:
•There may be a power problem (an alarm and power fault indication would normally be active).
•If there is only one Power Supply/Cooling Module present, the drive motors will spin up in a delayed sequence.
3.3.1Disk Drives LEDs
Each drive carrier incorporates two indicators, an upper (GREEN) and lower (AMBER). In normal operation the Green LED will be ON and will flicker as the drive operates.The amber indicator is OFF during normal operation and ON if there is a drive fault present.
3.4Power Down
To power the Enclosure down, either
•Switch off the Power Supply/Cooling modules installed in the Enclosure.
or
• Remove AC Mains at the power source
