Types of Cables Required
Before you actually install the host adapter, be sure you have the co r-
rect cables for your particular installation. The type of cables
required depends on the type of devices you plan to connect to the
SCSI bus: either external or internal. The type of c onnectors attached
to the cables also depends on the configuration of your installation.
Maximum Cable Lengths
When the SCSI bus contains a Fast SCSI host adapter, such as the
AMM-1570/1572, and one or more Fast SCSI devices, the total
length of all cables (internal and external) connected to the bus
should not exceed 3 meters to ensure reliable operation. If no Fast
SCSI devices are connected, the total length of all cables should not
exceed 6 meters.
External SCSI Connector Mounting Bracket
If you are connecting external SCSI devices to the AMM-1570/1572,
the external SCSI connector mounting bracket must be installed.
This bracket allows you to connect external SCSI devices to the
AMM-1570/1572. The mounting bracket is available from Adaptec
and is normally included with allAMM- 1570/1572 kits. Refer to
Installing the External SCSI Connector Mounting Bracket on page 3-8
for detailed instructions on installing t he bracket.
