front panel.
2. Push the MPI-8 Network Interface module firmly into the Backplane,
making sure it is properly seated in its slot.
3. Tighten the screws on the front panel of the MGC-50 that secure the
MPI-8 Network Interface module.
To mount the MPI Box on the Rack for the MGC-50:
1. Turn OFF power to the MCU and unplug it from AC power.
2. If the MCU is rack mounted, disconnect all external cables, dismount the
MCU from the rack and place it on a desktop or work table
3. Place the MPI box with is four 160-pin connectors facing the MGC-50
front panel between the two rails of the rack. Secure it to the rack with
the screws supplied with the MPI Box.
