MPM and MPM+ Configuration Modes
The RMX unit can work with either MPM or MPM+ (but not with both
simultaneously) media cards. The card Type installed in the system
determines the Card Configuration Mode. When MPM card is installed in
the MCU, it operates in MPM Mode. When MPM+ cards are installed, the
RMX operates in MPM+ Mode giving the administrator enhanced control
and monitoring of resource allocation and usage within the system.
MPM+ cards are supported only with d-type chassis and software version
4.0.
Each MPM+ card doubles the MPM capacities. Table 2 summarizes the
resource capacities of the various video resource types in an RMX
containing two MPM and MPM+ cards.

RMXs with 1000MB of memory are not subject to this limitation.
