Polycom RMX 1500/2000/4000 Administrator’s Guide
In Fixed Resource Capacity mode, the maximum number of resources is based on the
system license and the hardware configuration of the RMX. By default, these resources
are allocated as HD720p30 resources, the first time Fixed Resource Capacity mode is
activated.
Example: If two MPM+ cards are installed in the RMX, providing 160 video resources,
and the license was not upgraded accordingly, although the system capacity is higher,
resource availability for allocation does not change and remains according to the license
(80). Conversely, if two MPM+ cards are installed in the RMX, providing 160 video
resources, and the license is for 160 video resources, and one of the MPM+ cards is
removed, the resource availability for allocation is changed to 80.
Resource Usage
Continuous Presence
Video resources usage varies according to the video resolution used by the endpoints. The
higher the video resolution (quality), the greater the amount of video resources consumed
by the MCU.
Table 20-5 shows the number of video resources used for each resolution.
