nal power supply on and off. The ventilation
openings provide airflow for the drive while it is
operating. Make sure you do not block these
openings and that you keep them clear of dust.
Three light emitting diodes (LEDs) indicate the
status of the drive. The SCSI ID switch provides
the method for setting the drive’s SCSI ID. De-
tailed descriptions of the LEDs are provided in
Table 1.
Back Panel
The DigiDrive back panel has two SCSI connec-
tors and a power connector (see Figure 2). The
SCSI connectors are for attaching SCSI cables or
a SCSI terminator to the drive. An internal fan
pushes air through the enclosure, from front to
back, to cool the drive. The power connector is
where you attach the power cord.
Rack-Mounting Option
Digidesign offers an optional rack-mounting kit
(Digidesign model number MH163) that allows
you to mount a pair of DigiDrive enclosures in a
rack. The kit supports two drives mounted side-
by-side, occupying two rack units in an indus-
try-standard rack.
The DigiDrive is designed so that all of the con-
trols and indicators are accessible when
mounted. Instructions for mounting the drives
are included with the kit.

LED Function
Power
LED
The LED (green) is on when the drive is
turned on.
Activity
LED
The LED (yellow) is on when the drive is
turned on and then flickers as data is
transferred to and from the drive.
Thermal
LED
The LED (red) is on when the thermal
overload circuitry on the board senses
that the temperature inside the DigiD-
rive is too high. The LED lights for the
following reasons:
• Airflow through the drive is blocked.
• The internal fan has failed.
• Outside ambient temperature is too
hot.
Warning :
Operating the DigiDrive for extended
periods of time with the thermal indica-
tor on reduces the life expectancy of
the drive.
