Configuring The Boot Device; Scsi Cable - Dell 2100 User Manual

Configuring the Boot Device

If you plan to boot your system from a hard-disk drive,
the drive must be attached to the primary (or boot) con-
troller or built-in SCSI controller. You can select as the
primary controller either the built-in SCSI controller or
an optional controller installed in an expansion slot
through the Advanced menu in System Setup. Within the
Advanced menu, the PCI Scan Sequence option allows
you to select either the built-in SCSI controller or a con-
troller in an expansion slot as the primary controller.

SCSI Cable

Figure 9-2 shows the SCSI cable provided with the Dell
PowerEdge 2100 system.
CAUTION: Dell recommends that you use only
SCSI cables purchased from Dell. SCSI cables pur-
chased elsewhere are not guaranteed to work
reliably with PowerEdge 2100 systems.

Figure 9-2. SCSI Interface Cable
The cable shown in Figure 9-2 has six 68-pin connectors:
•
The connector at one end of the cable farthest from
the other connectors attaches to the SCSI controller
connector (SCSI) on the system board.
•
The two connectors in the middle of the cable attach
to SCSI devices in the external drive bays via 68-pin
to 50-pin adapters.
•
The three connectors at the other end of the cable
attach to the drives in the internal hard-disk drive
cage. The connector on the end of the cable should
be attached to the leftmost drive in the internal hard-
disk drive cage since the termination jumpers on this
drive can be accessed without removing the drive
cage.
