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 ATA 100 signal cable. ATA 100 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.
2. The DIMM options available for your computer are 128 MB, 256 MB, 512 MB, 1
GB, and 2 GB. Your computer supports a minimum of 256 MB and a maximum
of 8 GB of system memory.
3. The amount of usable memory will be reduced depending on the system
configuration. A certain amount of memory must be reserved for system
resources. The BIOS will display the total amount of installed memory and the
amount of configured memory.
4. Your computer comes with two 256 MB or 512 MB DIMMs (for a total of 512 MB
or 1024 MB) installed in the DIMM 3 and DIMM 4 memory connectors. When
you install additional DIMMs, be sure to install them as a pair in DIMM
connectors 1 and 2.
5. DIMMs must be installed in matched pairs. The first pair of DIMMs you install in
DIMM 3 and DIMM 4 memory connectors must be the same size, speed, type,
and technology. You can mix compatible DIMMs from various manufacturers. If
you install a second pair of DIMMs in DIMM 1 and DIMM 2 memory connectors,
they do not have to be the same size, speed, type, and technology as the
DIMMs you installed in DIMM 3 and DIMM 4 memory connectors. However, the
size, speed, type, and technology of the DIMMs you install in DIMM 1 and
DIMM 2 memory connectors must match each other.
6. Install only 133 MHz (memory bus), 2.5 V, 184-pin, double-data-rate (DDR),
PC2100, registered synchronous dynamic random-access memory (SDRAM)
