MPI-4/8 Hardware Installation for the MGC-100
The MPI-4/8 (Multi Protocol Interface) Network Interface card is inserted
into the MGC-100 unit.
The MPI box may be mounted on top of the MGC-100 using mounting
brackets, or on a separate 19” or 23” rack, as can be seen in Figure 2-8. When
installed on a 19” rack, the MPI box can be mounted directly on the rack.
When installed on a 23” rack, a mounting plate must be used. If the MGC-100
is rack mounted, there must be at least 6” free space above the MGC-100 to
be able to install the MPI Box on top of the MGC unit.
