Configuring the Digidesign 7-Slot
Expansion Chassis
Connecting the Expansion Chassis
Install the chassis host card:
1
Turn off the expansion chassis, your com-
puter, and any peripherals. Leave your com-
puter’s power cable plugged in so the computer
is grounded.
2
Open the computer case. For additional de-
tails on installing a card in your computer, refer
to its documentation.
3
Install the Digidesign Host Card in the lowest
numbered slot in your computer. This will be
the slot closest to the graphics card.
4
Attach a 2- or 4-foot expansion chassis cable
to the host card.
5
If using a SCSI HBA, install it in the highest
numbered remaining slot in your computer.
Install the chassis controller card:
1
Attach the chassis cable to the connector on
the back of the expansion chassis.
2
Attach the other end of the expansion chassis
cable to the controller card.
The Digidesign Expansion Chassis 7-slot is
supported on Mac OS X.
SBS Technologies was previously called
“Bit 3.”
