Installation

Connecting to a 68-pin Wide SCSI or LVD bus

To connect the drive to an LVD or SCSI wide bus, first turn off all power to the drive

and computer. Then attach the interface cable to the SCSI interface connector on the

back of the drive (see Figure 7).

SCSI Termination

The internal Scorpion 240 does

not

provide SCSI termination. For this reason, it

should not be the last device on a SCSI chain. Two termination examples are shown

in Figure 8 below. If the drive is the only SCSI device, attach the drive to the

connector which is next to last on the SCSI chain and attach a multi-mode terminator

to the last connector in the chain.

Connecting a power cable

Attach a four-pin power cable to the power connector on the back of the drive (see

Figure 7 above). The recommended power connector for the internal Scorpion 240 is

an AMP 1-48024-0 housing with AMP 60617-1 pins or equivalent.
