• 2-11. SCSI Termination
SCSI Termination
Remove SCSI ID jumpers on the SCSI hard drive before
placing it into the hot-swap tray. Read the user’s manual
of the hard drive for the location of the jumpers.
NOTE
Terminating the SCSI bus “chain” is necessary for SCSI devices to work
properly. Therefore, every SCSI connector on the DA-BP5 SCSI backplane
should either connect to a SCSI device or be terminated with an Ultra2
SCSI terminator as shown below.
