MPMx Resource Capacities per Card Type
The MPMx card offers increased resource capacities and capabilities. Two
MPM+ card assemblies are available:
•
MPMx-D
• MPMx-S
Table 3 summarizes the video capacities of the two MPMx card
assemblies.
MPMx, MPM+ and MPM Modes
• MPMx, MPM+ and MPM cards installed in the system cannot be
used simultaneously. Therefore, the RMX can operate in either MPM,
MPM+ or MPMx mode.
• MPMx Mode is the mode in which the RMX operates to fully utilize
the increased power and capacity of MPMx cards.
