If you are installing an SDLT drive, use the custom metal slide rails and screws that come with the option package. Follow the installation instructions that come with the option package; then, continue with step 7c. If you are installing a full-high DLT drive, use the custom metal slide rails and screws that are inside the 5.25-inch removable-media drive bays. Follow the installation instructions that come with the option package; then, continue with step 7d. Blue slide rails Filler panel Non-hot-swap bay Non-hot-swap drive Slide rails a. Remove the blue snap-on slide rails from inside the filler panel. b. Clip the slide rails onto the sides of the drive. c. Store the filler panel for later use. d. Align the slide rails on the drive with the guide rails in the bay; then, slide the drive into the bay until it snaps into place. 8. Replace the one-drop SCSI signal cable in your server with a two-drop SCSI signal cable, connecting the additional connector on the two-drop SCSI signal cable to the rear of the removable-media drive. 9. Connect a power cable to the back of the drive. A three-drop power cable for removable-media drives comes installed in your server. It is attached to the standard CD-ROM drive. The connectors are keyed and can be inserted only one way. 10. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 99. Memory technology transition IBM xSeries 235 is making a transition from 128 Mb to 256 Mb memory technology for 256 MB dual inline memory modules (DIMMs). To accommodate this transition, additional xSeries models are now available. These new models come with two 256 MB capacity, 256 Mb technology DIMMs. The Chipkill™ feature that is supported with the 256 MB capacity, 128 Mb technology DIMMs is not supported with the 256 Mb technology DIMMs. If you require DIMMs that support the Chipkill feature, a limited supply of the 256 MB, 128 Mb technology DIMMs will be available for order. In addition, IBM will continue to offer the Chipkill feature with DIMMs that have a capacity of 512 MB or greater. Chapter 4. Customer replaceable units 79
