Configuration B1 - Internal SCSI Devices Only
If SCSI devices are to be attached internal to your system, and cabled for easy
change to configuration C1, proceed as follows. See

then either a cabling problem exists, a fuse is blown, or both.
If it is a cabling problem, then fix it. If not, check the fuse on the P2
adapter module and on the MVMExxxx module, and replace if
necessary. The fuse on the P2 adapter module is for SCSI terminator
power. The fuse on the MVMExxxx is for Ethernet transceiver
power. The resistance of each fuse should be less than 1 ohm.
