Removing a DIMM

To remove DIMMs, complete the following steps:
1. Read the safety information that begins on page vii and "Installation guidelines"
2. Turn off the computer and all attached devices; then, disconnect all external

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.
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.
At the end of these cables are plastic connectors that can be attached to
different drives; these connectors vary in size. With Serial ATA drives, you can
use either a four-wire power cable or a five-wire Serial ATA power cable, but do
not use both at the same time (use one or the other).
that connect IDE, SATA, SCSI, and diskette drives to the system board. Two or
three types of signal cable come with the 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 the computer.
Note: The optical drive is attached to an ATA 100 signal cable. ATA 100
signal cables are color-coded. The blue connector is connected to the system
board. The black connector is connected to the master IDE device. The gray
middle connector is connected to the subordinate IDE device.
– Serial ATA: The narrower, black signal cable has two connectors. One is
connected to the SATA drive, and the other is connected to the connector on
the system board. Each SATA drive comes with a cable. If you install an
additional SATA 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 (SCSI B) on the system board. For more information about
connecting SCSI devices, see the SCSI documentation.
