SCSI Devices

The Pluggable Fast-Wide SCSI-2 and the Fast-SCSI-2 hard drives automatically set the SCSI ID
when plugged into the ProLiant 4500R Server. If the drives are part of a fault tolerant
configuration, the replaced drive will automatically begin rebuilding when it is installed.
The 32-Bit Fast-Wide SCSI-2 and the Fast-SCSI-2 Controller requires that a SCSI ID be set for
each SCSI device. The SCSI ID is set by jumpers ID2, ID1, and ID0 located on each SCSI
device. Table 4-2 shows the jumper settings for each SCSI ID and its recommended drive bay.
The following figure shows the physical locations of jumpers ID2, ID1, and ID0 on supported
options.
