Peripheral Device Connections
When connecting SCSI devices, follow these guidelines:
Verify the host computer system is shut down. There should be no data
transfer activity on the SCSI bus.
Verify power is off to the peripheral device before connecting it to the SCSI
bus.
Check whether your devices contain internal SCSI bus terminators or require
special terminates. If so, refer to your device manuals for instructions on
how to prevent excessive or improper SCSI bus termination.
Set switches or jumpers on your device(s) as appropriate.
Be sure each SCSI
device has a unique SCSI address.
Remember the default address of the SCSI
adapter is 7.
If a device other than the adapter also supplies termination power, its optimal
location is at the end of the SCSI bus. However, devices that supply
termination power can be distributed anywhere along the bus.
Use HP-supplied cables.
Do not exceed the maximum SCSI bus length of 25 meters.
This includes any
bus Iengths internal to peripheral devices. Refer to peripheral device or
system configuration manuals for internal device lengths.
Do not exceed the maximum number of devices supported.
(The differential
SCSI bus can support 16 devices including the SCSI adapter; however, only 7
SCSI Cascade Arrays can be connected. Note that SCSI Cascade Arrays are
only supported on HSC for the HP 9000 Series 700 on NIO adapters.)
