Troubleshooting

Before contacting your dealer, vatify the following. If the problem persists, contact your dealer.

The unit does not start (the POWER indicator does not light)

Verify that the power cable is connected correctly and that it is not damaged. Replace it if necessary.

Try another power outlet.

The POWER indicator flashes green

Verify that the cooling fan on the rear is operating normally.

The SDZ-S100 (SCSI model) and the host computer cannot communicate with each other

Verify that the host computer is on.

Verify that the SCSI ID of the unit is unique. Duplicate SCSI IDs cannot be used on one SCSI bus. The new ID becomes effective when you restart the unit or reset the SCSI bus. For details, see “Setting the SCSI ID (SDZ-S100 only)” on page 22.

Verify that the SCSI cable is correctly connected to the unit and the host computer. Push the connectors into their receptacles and, if necessary, tighten the screws until they are firmly seated. For details, see “Connecting the SCSI Bus Cable (SDZ-S100 only)” on page 27.

Verify that the SCSI bus is terminated correctly. For details, see “Connecting the SCSI Bus Cable (SDZ-S100 only)” on page 27.

Verify that all the connector pins are undamaged. Remove the terminator and cable connectors, and inspect them for bent, recessed, or missing pins. Replace the damaged component if necessary.

Verify whether there are too many SCSI devices on the SCSI bus. The maximum permissible number of SCSI devices on the SCSI bus is sixteen, including the SCSI host adapter card.

Verify that all the connected SCSI devices are LVD devices.

The SDZ-S100 is an LVD device. Do not connect HVD devices to the unit.

Verify the length of the SCSI cable. If your SDZ-S100 is the only device on the SCSI bus, make sure that the total length does not exceed 24.7 m (81 ft.). If there are other devices on the SCSI bus, make sure that the total length does not exceed 12 m (39.4 ft.). For details, see “Connecting the SCSI Bus Cable (SDZ-S100 only)” on page 27.
