Table 9. Automatically Assigned SCSI IDs Bay 1 2 3 4 ID 0 1 2 3 Note: The default SCSI ID for the SCSI backplane is 14. The default SCSI ID for each SCSI controller is 7. The processing sequence for SCSI devices is set through the SCSISelect Utility program. The default sequence proceeds from the lowest SCSI ID to the highest (0 to 6, then 8 to 15). Termination: The devices at both ends of the SCSI bus must be terminated. If you attach SCSI devices (internal or external), you must terminate the last device in the chain. The SCSI cable that comes in your server (connected to the SCSI backplane) is terminated. All the hot-swap drives in your server have automatic termination. Refer to the information that comes with the SCSI device for instructions about setting device jumpers or switches that control termination. Preinstallation Steps: Before you install drives in your server, verify that you have all the cables and any other equipment specified in the documentation that comes with the internal drive. You might also need to perform certain preinstallation activities. Some of the steps are required only during the initial installation of an option. 1. Choose the bay in which you want to install the drive. 2. Check the instructions that come with the drive to see if you need to set any switches or jumpers on the drive. Remove any SCSI ID jumpers from the drive. 3. To install the drive, go to "Installing a Drive in a Hot-Swap Bay." Installing a Drive in a Hot-Swap Bay: The bays on the right front of the server support hot-swap drives only. Note You do not have to turn off the server to install hot-swap drives in these bays. However, you must turn off the server when performing any steps that involve installing or removing cables. Before you begin: Read "Safety Information" on page 226. Read the documentation that comes with your drive. 138 Netfinity Server HMM
