Installing the Hardware
Note:
Some older very high-density connectors may be too
wide to fit between the external connectors on the
HP NetRAID-4M. If this is the case, upgrade to a newer
cable.
Follow these steps to connect external SCSI devices:
1
Make sure each device is assigned a unique SCSI ID number
from 0 to 6, or 8 to 15 (the HP NetRAID-4M is set to 7 by
default). No duplicate IDs are permitted on a channel. (See
SCSI ID Numbers
on page 2-14 for additional information.)
2
Attach the external SCSI cable with the very-high-density
68-pin connector at one end to the external connector (Channel
0, 1, 2 or 3) on the HP NetRAID-4M, as shown in Figure 2-6.
Figure 2-6. Attaching an External Cable with a Very High-density 68-pin
3
Attach the other end of the cable to one of the SCSI connectors
on the external SCSI device, as shown in Figure 2-7. (If you are
installing only one external SCSI device, attach a terminating
plug to the device unless the device terminates internally. For
more information, see the
HP Rack Storage/12 Installation
Guide
.)
