How to Install a SCSI Hard Drive?
1. SCSI ID – 0 thru 15 for Wide devices. Each device must have a unique SCSI ID.
2. SE I/O – No jumper so the device can multimode (default).
3. Motor Start – Disable motor start (default).
4. Delay Motor Start – Disable Delay motor start (default).
5. Write Protect – Write Protect Off (default).
6. Parity Check – Enable Parity check (default).
7. Terminator Power – Host adapter or other device provides term power (default).
Set the SCSI ID
Each SCSI device must have a unique SCSI ID. Most SCSI drives come with no jumpers on SCSI ID (SCSI ID = 0). The SCSI host adapter usually uses SCSI ID = 7. If you are installing a drive model ending in LC (uses 80-pin SCA connector), the host normally sets the ID over the I/O interface.
Only the devices at each physical end of a SCSI bus need to be terminated. The SCSI host adapter normally will provide termination for the controller end, therefore only terminate the last drive on the end of the cable. LVD drives do not have any provision for onboard termination; therefore, termination for LVD drives must come from another device or from an external terminator. Use only active SE or LVD terminators.
Configure Terminator Power
Active terminators must receive power from some source. The default configuration results in the drive not supplying termination power to the bus. Usually, the host adapter provides term power. Check the user’s manual for your host adapter. Drive models ending in LC cannot be configured to provide termination power to the bus.
1. Attach one end of the interface cable to the connector on the host adapter.
2. Attach the interface connector and a power connector to the drive.
3. Secure the drive using four 6-32 UNC mounting screws. DO NOT over-tighten the screws.
1. If the drive does not spin up, check that the power connector and the interface cable are securely attached.
2. If the drive spins, but there is no LED on/off activity, check the SCSI ID setting. Set the ID so that each device on the SCSI chain has a unique ID.
3. If the computer does not seem to recognize the drive, verify the drive is enabled by the SCSI host adapter setup utility.
4. If FDISK does not detect the drive, run the FDISK program with FDISK /STATUS to verify the drive is present
