Note: The SCSI cables that come with your server can only be used with the integrated SCSI controller with RAID capabilities. If a RAID controller other than the ServeRAID-5i is installed, you must use SCSI cables that are compatible with that controller. To select and order the correct cables for use with your RAID controller, contact your IBM reseller or IBM marketing representative. 8. Reinstall the adapter-support bracket in the server (see "Removing and installing the adapter-support bracket" on page 58). Important: To ensure proper cooling and server operation, you must keep the air-baffle cover closed. Note: You must reinstall the air-baffle assembly when you reinstall the adapter-support bracket. Make sure that no cable is under the adapter-support bracket or interferes with the center fans. 9. Reinstall the plastic dividers between the Active PCI-X adapter slots. 10. Reinstall the adapters that you removed. If you have not yet installed the ServeRAID controller, install it now. See "Installing a hot-plug adapter (slots 5 and 6)" on page 62 or "Installing a non-hot-plug adapter (any slot)" on page 64 for instructions for installing a hot-plug or non-hot-plug adapter; then, return to this step. 11. Replace the SCSI cable on the SCSI backplane with the SCSI cable for your new ServeRAID controller. The SCSI cable being replaced was one of the cables that was disconnected from the system board in step 7 on page 67. 12. Route the free end of the SCSI cable from the SCSI backplane through the adapter-support bracket opening and toward the ServeRAID controller (see the illustration in step 13). 13. Attach the free end of the SCSI cable to the selected internal SCSI channel connector on the ServeRAID controller. Make sure that the other end of the SCSI cable is attached to the connector on the SCSI backplane. Attention: When you route the SCSI cable, do not block the ventilated space around any of the fans. The following illustration shows how to route one SCSI cable to the ServeRAID controller. 68 xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
