Front Panel
Unit ID Number Indicator:
This LED displays the SCSI ID of the
SCSI drive carrier.
Key Lock/Drive Power Switch:
The keylock/drive power
switch performs three functions. The key switch assures proper
seating of the drive carrier within the receiving frame, turns
power to the drive carrier ON and OFF, and prevents unauthorized
removal or installation of the carrier. For the computer to access
data on the disk drive, the key must be turned counterclockwise
to the locked position.
LEDs:
Power - Steady glow indicates power ON.
Drive Activity- Steady glow indicates that drive is inserted
and ready for access. Flashing indicates drive is being ac-
cessed.
Fan - Green indicates normal fan operation. Red indicates fan failure.
OverTemp - Flashing red indicates overtemperature condi-
tions (default is 60° C). Audible alarm will also sound.
Reset Switch:
This will reset OverTemp LED back to Green, as
well as turn off audible alarm.
Carrier Fan:
Front-mounted carrier fan provides enhanced heat
dissipation (4.7 CFM).

DC Power Connector:
Uses a standard 4-pin DC Power Connec-
tor to accept DC power.
I/O Connector:
The input/output connector provides a standard
interface for all Ultra320 signals.
