Cabling an optional SCSI adapter
You can install an optional SCSI adapter in your computer to control the internal
hard disk drives. With a SCSI adapter installed you can configure the internal hard
disk drives into disk arrays. You can also cable a SCSI adapter to external hard
disk drives. See your SCSI adapter option documentation for complete instructions
for installing a SCSI adapter in your computer and for additional information about
SCSI adapters.
Note: An optional SCSI adapter or cable option is required to connect external
SCSI devices.
Complete the following steps to cable an optional SCSI adapter:
1. Install the SCSI adapter (see "Installing an adapter" on page 45).
2. Connect the SCSI-signal cable to the adapter and to one or more of the
signal-cable connectors to the rear of the SCSI devices.
3. Connect the SCSI-activity-indicator cable to the adapter and to the SCSI-LED
connector (J18) on the system board. See "System-board internal connectors"
on page 37 for the location of the SCSI-LED connector.
