Power and signal cables for internal drives
Your computer uses cables to connect IDE and SCSI devices to the power supply
and to the system board. (See “System-board internal connectors” on page 13 for
the location of system-board connectors.) Review the following information before
connecting power and signal cables to internal drives:
v
The drives that are preinstalled in your computer come with power and signal
cables attached. If you replace any drives, remember which cable is attached to
which drive.
v When you install a drive, ensure that one of the drive connectors of the signal
cable is connected to the drive and that the connector at the other end of the
signal cable is connected to the system board.
v If you have only one IDE device on a cable, it must be set as a primary device.
v If two IDE devices are used on a single cable, one must be designated as the
master device and the other as the subordinate device; otherwise, the computer
might not recognize some of the IDE devices. The master (primary) and
(subordinate (secondary) designation is determined by switch or jumper settings
on each IDE device.
v If two IDE devices are on a single cable, and only one is a hard disk drive, the
hard disk drive must be set as a master device.
The following cables are provided:
v
Power cables: Four-wire power cables connect the drives to the power supply.
At the end of these cables are plastic connectors that attach to different drives;
these connectors vary in size.
v Signal cables: Signal cables are typically flat cables, also called ribbon cables,
that connect IDE, SCSI, and diskette drives to the system board. Two or three
types of signal cables come with your computer:
– IDE: The wider IDE signal cable has three connectors.
If the cable has three connectors, one of these connectors is attached to the
drive, one is a spare, and the third attaches to the master or subordinate IDE
connector on the system board. The spare connector can be used to connect
additional IDE drives to your computer.
Note: The CD-ROM drive is attached to an ATA 100 signal cable. ATA 100
signal cables are color-coded. The blue connector attaches to the
system board. The black connector attaches to the master IDE device.
The gray middle connector attaches to the subordinate IDE device. If
you are installing an additional hard disk drive, you must change the
switch or jumper setting on the CD-ROM drive to make the drive a
subordinate device, set the switch or jumper setting on the new drive to
master, and change the connector used for the CD-ROM drive to the
gray middle connector. The new drive will connect to the black master
IDE device connector.
– Diskette drive: The narrower signal cable has two connectors, one attaches
to the diskette drive, and the other attaches to the connector (FDD1) on the
system board.
– SCSI: The following cables can be used to attach SCSI devices to the
integrated SCSI controller on the system board:
- An Ultra320 twisted ribbon cable connects the internal Ultra320 SCSI hard
disk drive to the SCSI connector on the system board. This cable has four
additional connectors for attaching more internal SCSI devices.
