11. Connect a power cable to the back of the drive (see Figure 4-23).
Note:
For 5 1/4-inch devices, power cables are provided in the
chassis for removable 5 1/4-inch media drives (including the CD-
ROM that is factory-installed). These power cables are
interchangeable for 5 1/4-inch devices only; you can connect any
one of them to any device you install in the 5 1/4-inch media bays.
The connectors are keyed and can be inserted in only one way.
For 3 1/2-inch diskette drives power cables are provided in the
chassis (including the diskette drive that is factory-installed). The
connectors are keyed and can be inserted in only one way.
12. Connect the data cable (see Figure 4-23) to the device; the SCSI connector is keyed
and can be inserted only one way.
Note:
For the 5 1/4-inch devices, be certain that you are using
the 50-pin SCSI data cable. This cable comes from the system I/O
board to the removable media bays and ends at the CD-ROM drive
in bay D. Do not confuse this cable with the 34-pin diskette drive
cable which begins on the system I/O board and ends at the diskette
drive in bay F.
13. Reinstall the top cover and the left front door. Power on the system.
