ID Conflict
When two devices share the same SCSI ID, a conflict occurs. This conflict must
be corrected before the SCSI bus will work properly. If a conflict occurs, check
all jumper settings to ensure that no devices on the bus share the same ID. Also
check all other devices on the bus outside of the enclosure.
Front Status LEDs
A status indicator is located on each canister. A 'Blue' light indicates normal drive
activity. A 'Red' light indicates a device fault. If all canisters display a 'Red' light
that is blinking on and off it indicates that there is a system fault. A system fault
is either a power supply or blower failure. The power supply and blowers are not
field replaceable units. A fault with either the power supply or blowers will
require replacement of the entire unit. Refer to
