SCSI controller Your computer is equipped with a SCSI controller integrated on the system board for use with Ultra160 SCSI devices. For computers with preinstalled software, information about the SCSI controller and connecting devices is available by selecting Get help → View documentation in the Access IBM menu. SCSI documentation is also on the Software Selections CD that comes with your computer. Power and signal cables for internal drives Your computer uses cables to connect internal drives to the power supply and system board. The drives that are preinstalled in your computer come with power and signal cables attached. If you replace any drives, it is important to remember which cable is attached to which drive. 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, also called ribbon cables, connect SCSI, IDE, and diskette drives to the system board. - The wider gray signal cable has three connectors. One of these connectors attaches to the CD-ROM drive, one is available for a device installed in bay 1, and one attaches to the secondary IDE connector on the system board. - The narrower gray signal cable has two connectors for attaching the diskette drive to the diskette-drive connector on the system board.

Power and signal cables for internal drives
Your computer uses cables to connect internal drives to the power supply
and system board.
The drives that are preinstalled in your computer come
with power and signal cables attached.
If you replace any drives, it is
important to remember which cable is attached to which drive.
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
, also called
ribbon cables
, connect SCSI, IDE, and
diskette drives to the system board.
The wider gray signal cable has three connectors.
One of these
connectors attaches to the CD-ROM drive, one is available for a
device installed in bay 1, and one attaches to the secondary IDE
connector on the system board.
The narrower gray signal cable has two connectors for attaching
the diskette drive to the diskette-drive connector on the system
board.
