16. Connect a power cable to the back of the drive
(see Figure 5-25).
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.
17. Connect the ribbon data cable (Figure 5-25) to the
device; the connector is keyed and can be inserted
only one way.
Note: For the 5 1/4-inch media devices be certain
that you are using the 50-pin SCSI data cable. This
cable comes from the system board to the removable
media bays and ends at the CD-ROM reader in
bay A. Do not confuse this cable with the 34-pin
diskette drive cable which begins on the system
board and ends at the diskette drive in bay E.
