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. Check the back of the unit to determine
which fault has occurred. Refer to Chapter 5 for blower fault indicator location
and to Chapter 6 for power supply fault indicator location.
