The 68-pin (internal) SCSI cable in your Precision 410 system connects SCSI devices
(normally SCSI hard-disk drives) to the 7890 Ultra2/Wide LVD controller.
The connector at the end of the cable attaches to the Ultra2/Wide LVD primary
SCSI controller connector labeled “SCSI_ULTRA2” on the system board.
The other connectors on the cable are used for attaching up to two SCSI hard-
disk drives in the internal drive bays (see Figure 10-13).
The 50-pin (internal) Narrow SCSI cable connects SCSI devices to the 7880 Ultra/Wide
controller.
The narrow connector at the end of the cable attaches to the secondary SCSI
controller connector labeled “SCSI_NARROW” on the system board.
The other connectors on the cable are used for attaching SCSI devices installed in
the externally accessible drive bays (see Figure 10-13).
An optional shielded external cable with a 68-pin connector is used for attaching an
external SCSI device to the 7880 external SCSI connector on the system back panel.
Refer to the documentation that came with the external SCSI device for information
on how to connect the device, set its SCSI ID, and disable termination.
