Configuration F - External SCSI Devices Only

If SCSI devices are to be attached external to your system and the MVME-xxxx is
not at one end of the cable, proceed as follows. See

If it is a cabling problem, then fix it. If not, check the fuse on the P2
adapter module and on the VMEmodule, and replace if necessary.
The fuse on the P2 adapter module is for SCSI terminator power.
