The RMX unit can work with either MPMx or MPMRx (but not with both simultaneously) media cards. The
card type installed in the system determines the Card Configuration Mode. ISDN support is the same for all

Description
The CNTL4000 module controls and manages the RMX 4000. The CNTL 4000
ComExpress Intel i5 Processor, a 64GB Half Slim SSD and 8Gb
module has a
DDR RAM
.
The Operating System is Linux.
The Fabric Switch Module performs media processing functions on the RMX 4000
unit. This card is managed by the RTM IP 4000.
The AC Power Supply drawers are located below the MPMx/MPMRx Cards and are
connected to the backplane by means of a power connector. Operating at 100-240
volts AC 50/60 Hz all power supplies have built-in load sharing capabilities.
On systems with DC current, the PEM provides direct current to the rear of the RMX
through the backplane.
Eight fans are mounted sideways and stacked in a drawer. The drawer is connected to
the Back-plane by a connector.
Airflow is from right to left, and out the side of the MCU. Each time a board
temperature sensor passes one of its thresholds an event is sent to the ShelfManager,
whereupon an threshold alert is posted on the RMX Manager, and increases the fans
speed. There are currently three sets of thresholds: Normal, Major and Critical. When
the temperature reaches a critical threshold (and the fan's speed increase did not
resolve the issue), the controller of the relevant board initiates a shut down.
The MPMx cards, perform the various RTP, audio and video processing functions on
the RMX 4000 unit. TI processors are at the core of each MPMx card which are
available in the following assemblies:
• MPMx -S
• MPMx -D
Note:
RMX 4000 systems, which are shipped with MPMx media cards and CNTL 4000
Module BRD2535x-L0, do not support software version preceding V8.2. Ensure that
software appropriate to the MCU hardware configuration is installed in the MCU.
• An MPMx located (on the front panel) must face opposite (same slot level) an RTM
LAN card (installed on the rear panel). For more information, see
four LAN Ports .
The MPMRx cards, perform the various RTP, audio and video processing functions on
the RMX 4000 unit. TI processors are at the core of each MPMRx card which is
available in the following assembly:
• MPMRx -D
• Note: An MPMRx card on the front of the RMX must always be seated or connected
opposite to either an RTM LAN or RTM ISDN card on the rear of the chassis. For
more information, see RTM LAN Card - four LAN Ports
