Notes:

1. See “Setting SCSI IDs for External Devices” on page 209 for rules about setting SCSI IDs for devices.

2. This is the default jumper setting.

The processing sequence for SCSI devices is set through the SCSISelect Utility program (refer to the SCSI Software User's Guide for more information). The sequence proceeds from the lowest SCSI ID to the highest (0 to 6, then 8 to 15).

Termination (Internal SCSI Devices)

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.

Note: All of the preinstalled hot-swap drives in your server have automatic termination.

If you attach internal SCSI devices to one of the SCSI-2 internal connectors, you must terminate the last internal device on the bus (cable) and disable the termination on the other devices connected to the internal SCSI controller. The SCSI-2 controller is already terminated.
