To avoid damaging components, before you connect or disconnect a SCSI cable,
turn off the printer and all SCSI devices.
Before you turn on the printer, turn on the SCSI devices.
1.
Turn off the printer and the SCSI devices.
2.
For each SCSI device, set a unique SCSI ID number (0 – 6; the printer is 7).
3.
Connect the SCSI cable to the first SCSI device; you will need high-density
SCSI connectors. Connect the second device to the first and so on.
4.
Connect the SCSI cable attached to the first SCSI device to the printer port
marked "SCSI."
5.
Attach the terminator to the last device in the SCSI chain (not required if
the SCSI device has a built-in terminator). Note the following:
The printer has an internal terminator.
The printer must always be at one end of the chain with a
terminator (or a device with an internal terminator) at the other
end.
Most SCSI external hard disks are shipped with an internal
terminator that is active. If you are connecting multiple hard disks,
you will need to deactivate the terminators on all devices except for
the last device on the daisy chain. See the documentation provided
with the disk for instructions.
For a scanner's termination, refer to its documentation.
6.
If you have connected an uninitialized SCSI hard disk, see "Initializing a
formatted SCSI device" on page 89.
