On-board SCSI Switch terminators can be powered by internal 5-volt power or
externally from SCSI bus “termination power.”

NOTE
The standard factory default connects internal terminators to internal
5 volts.
5.4 Selecting External Terminator Power
The SCSI Switch can supply external terminator power via an internal resettable
fuse. This fuse supplies 1 amp at 5 volts to the termination power signal. The SCSI
Switch contains internal protection and will not be affected if other SCSI devices
provide terminator power.

NOTE
Factory Default is “Enabled” on all ports.
