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 the drive connector at the end of the signal
cable is connected to the drive and that the drive connector at the other end is
connected to the system board. This reduces electronic noise from the computer.
v If two IDE devices are used on a single cable, one must be designated as the
primary device and the other as the secondary device; otherwise, the computer
might not recognize some of the IDE devices. The primary and 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 primary device.
v If you have only one IDE device on a cable, it must be set as a primary device.
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 E Pro computer uses industry-standard dual inline
memory modules (DIMMs).
Do the following to install a DIMM:
Attention: When handling static-sensitive devices, take precautions to avoid
damage from static electricity. For details on handling these devices, see "Handling
static-sensitive devices" on page 39.
1. Review the safety precautions listed in the "Safety information" on page vii.
2. Turn off the computer and all attached devices. Disconnect all external cables
and power cords; then remove the cover. See "Removing the side cover" on
page 60 for details.
3. Remove the support bracket. See "Removing the support bracket" on page 61.
4. Touch the static-protective package containing the DIMM to any unpainted
metal surface on the computer. Then remove the new DIMM from the package.
5. Open the retaining clips and, if necessary, remove any existing DIMM.
6. Gently open the retaining clip on each end of the DIMM slot. Turn the DIMM
so that the pins align correctly with the connector.
