SCSI Configuration Information
Installing a RAID Controller Card
Your system features a hard-drive bay that contains up to eight 1-inch SCSI hard drives. Your system also features a peripheral bay that can be used for an
additional four 1-inch SCSI hard drives or an internal tape drive. A CD drive and a diskette drive are mounted together on a tray that slides in and out of the
front panel and connects to a connector inside the system. This connector is cabled to the peripheral riser card. This allows the diskette and CD drives to be
serviced without removing system covers or connecting and disconnecting cables. This section contains instructions for replacing these devices.
SCSI Interface Cables
If you are installing a SCSI tape drive in the peripheral bay, you must connect it to the I/O riser card. If you are installing SCSI hard drives in the peripheral
bay, you must connect the interface cable from the peripheral bay's daughter card to a RAID controller card.
These interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends.
When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.
SCSI Configuration Information
Although SCSI devices are installed in essentially the same way as other devices, their configuration requirements are different. To configure a SCSI device
installed in the peripheral bay, follow the guidelines in the following subsections.
SCSI ID Numbers
Each device attached to a SCSI host adapter must have a unique SCSI ID number from 0 to 15.
A SCSI tape drive is configured as SCSI ID 6 (the default ID number for a tape drive).
Device Termination
SCSI logic requires that the two devices at opposite ends of the SCSI chain be terminated and that all devices in between be unterminated. The SCSI cable
included in the upgrade kit has an active terminator installed at the end of the cable. Therefore, when configuring the devices in the peripheral bay, you should
disable the device's termination.
Peripheral Bay
The peripheral bay can be used for an additional four 1-inch SCSI hard drives or a tape drive.
Installing Hard Drives in the Peripheral Bay
Installing hard drives in the peripheral bay is identical to installing hard drives in the hard drive bay (see "
" found later in this document).
Installing Internal Tape Drives in the Peripheral Bay
Internal tape drives are connected directly to the I/O riser card.
1.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2.
Remove the microprocessor tray (see "
Removing the Microprocessor Tray
" in "Installing System Board Options").
3.
Remove the inserts from the front of the peripheral bay.
NOTE:
There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable according to ID number.
CAUTION:
Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
"
Safety First—For You and Your System
" in "Troubleshooting Your System."

See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
