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 first, then turn off the SCSI devices.
2.
For each SCSI device, set a unique SCSI ID number (0 – 6; the printer is 7).
3.
Connect the SCSI devices to the printer:
a.
Connect the SCSI cables to the SCSI devices; you will need a
high-density SCSI connector.
b.
Check termination:
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 hard disks are shipped with an internal terminator that
is active.
Place SCSI devices at the end of the SCSI chain, making sure that no
other SCSI devices are terminated (only the last device on the daisy
chain). If you are connecting multiple hard disks and most hard
disks are internal terminated, you will need to de-activate the
terminators in all devices except for the last device on the daisy
chain.
For scanner’s termination, refer to its documentation.
4.
Connect the SCSI cables to the printer.
5.
If you have a SCSI hard disk, download the Enable/Disable utility file to it;
refer to “Using Printer Utilities” on page 135.
