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.

Turn off the printer first, then turn off the SCSI devices.

For each SCSI device, set a unique SCSI ID number (0 – 5; the printer is 7  
and the optional IDE internal hard drive is 6).

Connect the SCSI devices to the printer:

Connect the SCSI cables to the SCSI devices; you will need 
high-density SCSI connectors. 

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.  If you are connecting multiple SCSI devices, you will need 
to de-activate the terminators in all devices except for the last 
device on the daisy chain.

■

For termination information on any SCSI device, refer to its 
documentation.

Connect the SCSI cable to the printer.  

Turn on the SCSI devices first, and then turn on the printer.

If you have a SCSI hard disk, see “Initializing a formatted SCSI device” on 
page 105, and “Enabling and disabling Sys/Start Job execution” on 
page 106.
