7. Connect one of the unused connectors on the SCSI cable to the wide

connector on the drive (see the illustration below).

Find the internal SCSI cable inside the computer (it is the wide ﬂat ribbon

cable connected to the hard drive. The internal SCSI cable should have one

or two unused connectors on it. You may have to detach and re-attach the

SCSI connectors on one or more other drives to get connectors where you

need them. Remember, this is SCSI, so the ends (but no other devices) must

be terminated. See

Ensuring proper termination

on page 18 for details.

Note:

There is a

key

in the middle of the top of the SCSI connector and a

notch

in the cable connector which matches the key, to ensure that the

cable is not plugged in upside down. If the cable resists being plugged in,

check to make sure the key and slot are mating correctly.

8. Find an unused 4-pin power cable in the set of cables coming from

the power supply (the power supply is in the right rear of the

computer, on the bottom) and connect that cable to the rear of the

drive, being careful to match the beveled corners of the plug to

those of the socket (see the illustration above).
