2. Connect one end of the 0.8-meter SCSI cable to your host system.
You can connect the SCSI cable to an UltraSCSI PCI host adapter or the on-board
SCSI port, as long as it’s an UltraSCSI port. Refer to the documentation that came
with your host system for the location of the UltraSCSI port on the host system.
3. Connect the other end of the SCSI cable to the SCSI IN port at the rear of the
StorEdge S1 storage enclosure.

4. Determine if this StorEdge S1 storage enclosure is at the beginning or the end of
the SCSI chain.
■
If this storage enclosure is at the end of the SCSI chain (you are not connecting any
other peripherals to your host system), go to “Connecting the Power Cables” on
page 50.
■
If this storage enclosure is at the beginning of the SCSI chain (if you are going to
daisy-chain other StorEdge S1 storage enclosures or peripherals off of this one),
keep the following things in mind:
■
If you have an LVD SCSI connection, you cannot daisy-chain more than four
StorEdge S1 storage enclosures together. If you have a single-ended SCSI
connection, you cannot daisy-chain more than two StorEdge S1 storage
enclosures together.
■
If you are adding a single-ended peripheral (such as the Netra st D130
enclosure) to the SCSI chain, you can only daisy-chain one StorEdge S1 along
with the peripheral.
See “To Determine the Available SCSI IDs” on page 39 for more information on
assigning SCSI ID addresses.
■
The overall SCSI bus length cannot exceed 12 meters for LVD SCSI and
3 meters for single-ended SCSI. The SCSI bus length for the cables inside the
StorEdge S1 storage enclosure is 1 meter. If you are connecting another type of
peripheral in this daisy-chain, refer to the documentation that you received with
that peripheral for its internal SCSI bus length.
5. Connect one end of the SCSI cable to the SCSI OUT port of the first StorEdge S1
storage enclosure.
6. Connect the other end of the SCSI cable to the SCSI IN port on the second
StorEdge S1 storage enclosure or peripheral.
