General Procedure for Installing SCSI Devices
Configure and install one or more SCSI devices in your computer as follows:
1. Determine which connector on the internal SCSI cable you will attach to each SCSI device.
See SCSI Configuration Guidelines
.
2. Unpack each SCSI device and prepare it for installation.
CAUTION: Ground yourself by touching an unpainted metal surface on the back of the computer.
CAUTION: When you unpack the drive, do not set it on a hard surface, which may damage the drive.
Instead, set the drive on a surface, such as a foam pad, that will sufficiently cushion it.
Configure the device for a SCSI ID number and disable termination, if necessary. For instructions, see the
documentation that came with the SCSI device as well as SCSI Configuration Guidelines
.
3. Install the SCSI devices as appropriate.
To install a SCSI hard-disk drive, complete the steps in Installing a Hard-Disk Drive in the Internal
Hard-Disk Drive Cage. Then continue with step 4 of this procedure.
To install a SCSI tape drive or DAT drive, complete steps 2 through 6 of Installing a Drive in a 5.25-
Inch Drive Bay. Then continue with step 4 of this procedure.
If you are installing a SCSI host adapter card, configure the card and install it in an empty expansion
slot (see Installing an Expansion Card) If you attach any SCSI hard-disk drives to the host adapter
card, connect the hard-disk drive access cable to the SCSI host adapter card and to the AUX_LED
connector on the system board (see the System Board Features illustration).
4. Attach the SCSI cable to each SCSI device.
For additional instructions on connecting SCSI devices, see SCSI Cables.
If you are installing an internal SCSI device, firmly press the SCSI cable's header connector onto the 68-pin
connector on the back of the device.
CAUTION: You must match the colored strip on the cable with pin 1 on the drive's interface
connector to avoid possible damage to your system.
5. Connect a DC power cable to the power input connector on the SCSI device.
Check all other cable connections. Fold all internal cables out of the way to provide airflow for the fan or cooling
vents.
6. If you installed an externally accessible device, remove the front bezel and remove the front-panel insert for the
