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, it is important to 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 always connected to a drive, and ensure 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 detect 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). Note: The desktop model does not support installing memory in DIMM connector 3. 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 cover" on page 43 or for details. 3. Lift the frame support bracket. See "Removing the frame support bracket" on page 44. 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. Gently open the retaining clip on each end of the DIMM slot. Turn the DIMM so that the pins align correctly with the connector. Chapter 5.
