RealPresence Collaboration Server (RMX) 2000 Components and Components Replacement
On the RealPresence Collaboration Server (RMX) 2000, LAN port 2 is used to connect the LAN cable. LAN
port 1 is the redundant port.
Note: Multiple Networks and LAN Redundancy
The RTM LAN type card is always required with Multiple Networks and LAN Redundancy
configurations.
Figure below shows the RTM LAN card with four LAN ports
RTM LAN card - four LAN ports
Ports on the RTM LAN card with four LAN ports are:
● Four 1Gb LAN ports No. 1-4
● One DBG - Debug port, for internal use.
● ARM/CM - Switch, for internal use.
RTM LAN card - two LAN ports
The RTM LAN card routes data between the MPMRx cards and components of the system, and sends
media by IP packets and provides connectivity to external IP networks.
Note: RTM LAN card with two LAN ports
• 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.
• The RTM LAN type card is always required with Multiple Networks and LAN Redundancy
configurations.
However on systems with ISDN networks, the RTM ISDN can also be used instead of the RTM LAN.
An RTM LAN card must connect directly to an MPMRx card. In an RMX with a single MPMRx card, the RTM
LAN card must be installed in the top slot rear panel slot at the same level as the MPMRx card.
The RTM LAN card with two LAN ports is shown next:
