2.1 Drive Module Faults
Disk drive status is monitored by a Green LED and an Amber LED mounted on the front of each Drive Carrier
Module, providing the following indications:
2.1.1 Front Dummy Fascias
Front dummy fascias must be fitted to all unused drive bays to maintain a balanced air flow.
Important If any bays are not filled with either a drive or fascia the System LED on the ESI/Ops Panel will
flash.
2.1.2 Auto Start Failure
Unless otherwise selected at installation time, all drives in the enclosure should automatically start their motors after
power is applied. If this has not occurred one of the following conditions may exist/
• The 'Manual start option jumper has been fitted to the ESI/Ops Panel module during installation, thus disabling
the drive auto start function.
• There is a power problem (An alarm and power fault indication would normally be active).
• Only 1 Power Supply/Cooling module is fitted in an enclosure with:
– drive Type 3 selected
– more than eight drives installed.
A full complement of two Power Supply/Cooling modules are required to auto start.
Note: The System LED will flash Green/Amber.
