Configuration E - External SCSI Devices Only
If SCSI devices are to be attached external to your system and the MVMExxxx is
at one end of the cable, proceed as follows. See
.
1. The MVMExxxx is at one end of the cable, so terminators must be
installed on the P2 adapter module.
2. The MVME712M is not at one end of the cable, so terminators must
be removed from the MVME712M.
3. Install the P2 adapter module to the backplane directly in line with
the P2 connector on the MVMExxxx. Be sure to orient pin 1 of the
adapter with pin 1 of the backplane connector.
4. Attach the furnished 50-conductor cable from connector J3 on the
MVME712M to connector J3 on the P2 adapter.
5. Attach the furnished 64-conductor cable from connector J2 on the
P2 adapter to connector J2 on the MVME712M. Be sure to orient
cable pin 1 with connector pin 1.
6. Insert the MVME712M module into the selected slots and tighten
the attaching screws, making good contact with the transverse
mounting rails to minimize RF emissions.
7. Connect a user-supplied 50-conductor cable with compatible
pinouts from the SCSI connector on the front panel of the
MVME712M to the external SCSI devices.
8. Terminators must be installed on the last SCSI device on the cable.
9. Make sure that cables will not be pinched by the cover and install
the cover that you previously removed.
10. Connect the power cable to the AC power source and turn the unit
on.
11. Both LEDs on the MVME712M should be lit. If not lit, 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 VMEmodule, 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.
