Termination Power (TERMPWR)
WD Enterprise drives have the ability to supply +5V to
the SCSI bus for termination. Option block pins 27 and
28 are dedicated to TERMPWR. If you want the drive to
supply TERMPWR to the SCSI bus, install a jumper as
shown in Figure 10. To disable TERMPWR, no jumper is
required.
Consult your system or host bus adapter documentation to
determine if the SCSI bus supplies termination power.
(Most systems do supply termination power). If your
system does not, then you must use the power supplied by
the WD Enterprise drive.
NOTE: Termination power from the hard drive is required
only if the host bus adapter does not supply it.
However, both devices can provide termination
power with no detrimental effects to the system.
