IBM IntelliStation M Pro Installation Manual page 56

The following cables are provided:
v Power cables: Four-wire power cables connect the drives to the power supply.
v Signal cables: Signal cables are typically flat cables, also called ribbon cables,
Installing memory modules
The following notes describe the types of dual inline memory modules (DIMMs) that
your computer supports and other information that you must consider when
installing DIMMs.
Notes:
1. Your IntelliStation M Pro computer uses industry-standard PC2700 or PC3200
2. The system board contains four DIMM connectors and supports two-way
3. The DIMM options available for your computer are 256 MB, 512 MB, and 1 GB

IBM IntelliStation M Pro Types 6220 and 6230: Installation Guide
At the end of these cables are plastic connectors that attach to different drives;
these connectors vary in size. You can use either a four-wire power cable or
serial ATA power cable with serial ATA drives, but do not use both at the same
time (use one or the other).
that connect parallel IDE, serial ATA, 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.
– Serial ATA: The narrower, black signal cable has two connectors. One
attaches to the serial ATA drive, and the other is attaches to the connector on
the system board. Each serial ATA drive comes with a cable. If you install an
additional serial ATA drive, you will need an additional cable.
– 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.
- A round SCSI cable connects external SCSI devices to the integrated SCSI
controller on the system board. For more information about connecting
SCSI devices, see the SCSI documentation.
