no drive can be installed in the other bay of the lower drive
bracket.
4. To properly mount a 3.5-inch drive into bay 1 or 2 (5.25-inch
bays), use a 3.5-inch conversion kit for a 5.25-inch bay. For
more information, see your IBM reseller or IBM marketing

Power and signal cables
Your server uses cables to connect integrated drive electronics (IDE)
and SCSI drives to the power supply and system board. The
following cables are provided:
Four-wire power cables connect most drives to the power supply.
At the end of these cables are plastic connectors that attach to
different drives; these connectors vary in size. Also, certain
power cables attach to the system board.
Flat signal cables for connecting SCSI, IDE, and diskette drives to
the system board; signal cables are sometimes called ribbon
cables. There are four ribbon signal cables that come with your
server:
– The wider signal cable has three connectors. One of these
connectors is attached to the CD-ROM drive, one is a spare,
and the third attaches to the primary IDE connector on the
system board.
– One of the narrower signal cables has two connectors. One
of the connectors is attached to the diskette drive and the
other is attached to the diskette-drive connector on the
system board.
– One 68-pin SCSI ribbon cable has five connectors. Use this
cable to connect internal SCSI drives to the SCSI controller
channel B connector on the system board.
– One 68-pin SCSI ribbon cable has two connectors. One end
is attached to the external SCSI connector on the back of the
server. The other end is attached to the SCSI controller
channel A connector on the system board. Attach external
SCSI devices to the external SCSI connector on the back of
the server.
