Connecting the SCSI interface cable
The external Viper 200 provides two 68-pin, shielded
connectors on the rear panel of the enclosure (as shown in
Figure 14). Either connector can be used as a SCSI IN or
SCSI OUT connection, so you can use either connector to
attach the drive to a host computer or to another SCSI
device.
Note: Turn off all power before connecting or disconnecting
SCSI termination
If the Viper drive is the last device or the only device in a

SCSI connector. See Figure 15 below for two SCSI
termination examples. You can purchase terminating plugs
on the web at http://buytape.seagate.com.
