Step 6—Connect the power connector
Connect the 4-pin power connector of the computer to the 4-
pin power connector of the scanner. Note that both
connectors are keyed so that one side of the connector is
beveled. Be careful to insure that the beveled edges are
properly aligned. Under certain circumstances, it is possible to
force the connector in at an improper angle, thereby creating a
reversed connection. Extreme damage can occur to the
scanner should this happen. Make sure that the connection is
correct.
Note: An optional Y-adapter may be necessary if there are no
available power connectors in the computer.
Warning! Do not attempt to connect power to the scanner
with the computer power on.
Step 7—Slide the scanner into the computer
Once the power connection is made, carefully slide the scanner
the rest of the way into the computer. Pull gently on the SCSI
cable with one hand to provide slight tension on the cable while
the scanner is being pushed in. Do not tug on the cable or
allow the cable to fold while pushing in the scanner.
Step 8—Screw down the rail stops
Once the scanner has been pushed into the computer,
reposition or reinsert the lock tabs mentioned in Step 3 above.
The tabs should slide in front of the scanner guide rails, thereby
locking the scanner in place.
5.3 Setting the SCSI ID
Up to eight devices can share a SCSI host. These are each
identified by SCSI ID numbers. Thus, a SCSI ID can have a
value between 0 and 7. There are no implicit regulations
regarding the use of these numbers. Typically, the computer
itself would be SCSI ID number 7, while the SCSI peripherals
would be 0 through 6.
A minimum of two devices must be connected to any SCSI bus.
In this case, one is designated as the initiator while the other is
the target. It is possible to have many configurations of initiators
and targets on a bus. More than one initiator can be present
on a SCSI bus. The typical configuration is one initiator and one
or more targets. The internal-mount scanner is always a target.
In the case we show below, the only initiator is the computer.
The SCSI ID is typically set by a switch on the rear of the SCSI
peripherals. The default SCSI ID number set at the factory is ID
#5.
