SCSI FIBER OPTIC EXTENDER
5.3 Internal Terminator Power and Fuse
The SCSI Fiber Optic Extender can supply external terminator power via an
internal resettable fuse. This fuse supplies 1 amp at 5 volts to the TERMPWR
signal. The POWERLINK contains internal protection and will not be affected if
other SCSI devices provide terminator power.
To enable External Terminator Power, install jumper as shown in
Figure 5-2
.
NOTE
The default setting is “INSTALLED” (supply external terminator power).
Figure 5-2. External terminator power.
5.4 Selecting Internal Terminator Power
Internal SCSI Fiber Optic Extender termination can be powered by internal 5-volt
power or externally from the SCSI bus termination power line. Depending on
system applications, it may be advantageous to power the internal terminators by
the SCSI peripheral or computer.
NOTE
The default setting is “INTERNAL 5V.”
