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.
