SCSI Termination

The I/O+ board in slot 1 controls the internal media tray devices. Therefore, the
external SCSI connector on the I/O+ board in slot 1 of a system must be terminated
with a single-ended SCSI terminator (

Hot-Plug Feature

The hot-plug feature enables you to insert a new board into a powered-on system,
despite the system being "live," or being supplied with electrical power. When the
hot-plug feature is used to add a board to a powered-on system, the system will not
use the new board until the system is rebooted.
Sun Enterprise Systems have extensive error detection mechanisms that detect failed
components (I/O boards, CPU Memory boards, CPUs, memory) during Power on
Self Test (POST). When a failed component or system board is detected, POST will
put that board into lower-power mode and reconfigure the systems so that failed
boards are no longer accessible.
Caution – If the message: NOTICE: Hot Plug not supported in this
system is displayed during boot, do NOT attempt hot-plug in this system or
damage to the hardware will occur.
