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 The computer has two IDE buses, primary and secondary. Each of these buses
supports up to two IDE devices. The primary IDE bus uses connector IDE1 on
the system board and the secondary IDE bus uses connector IDE2.
v
If you have only one IDE device on a cable, it must be set as a master 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 and subordinate
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 can be attached 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 cable come with your computer.
– IDE: The wider IDE signal cable has three connectors. One of these
connectors is attached to the drive, one is a spare, and the third is attached to
the primary or secondary IDE connector on the system board. The spare
connector can be used to connect additional IDE drives to your computer.
The CD-ROM drive is attached to an ATA100 signal cable. ATA100 signal
cables are color-coded. The blue connector is attached to the system board.
The black connector is attached to the master IDE device. The gray middle
connector is attached 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 be
connected to the black master IDE device connector.
– Diskette drive: The narrower signal cable has two connectors. One is
attached to the diskette drive, and the other is attached to the connector
(FDD1) on the system board.
– SCSI: A round SCSI cable connects SCSI devices to the integrated SCSI
controller with RAID capabilities on the system board. For more information
about connecting SCSI devices, see the SCSI documentation.
Installing memory modules
Adding memory to your computer is an easy way to make programs run faster. You
can increase the amount of memory in your computer by installing memory
modules. Your IntelliStation Z Pro computer uses industry-standard PC2100
double-data-rate (DDR) dual inline memory modules (DIMMs).
Notes:
1. The system board contains four DIMM connectors and supports two-way
memory interleaving.
