To avoid damaging components, before you connect or disconnect a SCSI cable, turn off the printer, then turn off the SCSI device.

1. Turn off the printer and the SCSI device.
2. On the SCSI device, set a unique SCSI ID number ( 0 - 6; the printer is 7 ).
3. Connect the SCSI device to the printer:
1. Connect the SCSI cable to the SCSI device; you will need a high-density SCSI connector.
2. Check termination (not required if the SCSI device has a built-in terminator).
• 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 the SCSI device does not have an internal terminator, add one.

NOTE Devices that require power from another device (TERMPWR pin 38) may not terminate properly.

• For scanner's termination, refer to its documentation.
3. Connect the SCSI cable to the printer.
4. Turn on the SCSI device first, and then turn on the printer.
6. If you have a SCSI hard disk, see Initializing a formatted SCSI device and Enabling and disabling SysStart Job execution.
