Connecting the SCSI interface cable
The Scorpion 240 provides two 68-pin, shielded connectors on the rear panel of the
enclosure. Either connector can be used as a SCSI IN or SCSI OUT connection (you
can use either connector to attach the drive to the host computer or to another SCSI
device).
Turn off your computer and all SCSI devices. Then attach a SCSI cable from the
host adapter or from another (unterminated) SCSI device to the Scorpion 240.
Note: The Scorpion 240 will not operate in a SCSI-1 environment.
SCSI Termination
If the Scorpion 240 is the last device or the only device in a SCSI chain, you must
install a terminating plug on the unused SCSI connector. See Figure 10 for two SCSI
termination examples. You can purchase a terminator for the Scorpion 240 (part
number 10006525-001) on the web at http://buytape.seagate.com.

Connecting the power cord
Attach the power cord securely to the power connector on the back of the drive. The
location of the power connector is shown in Figure 9 on the previous page.
