RealPresence Collaboration Server (RMX) 4000 Components and Components Replacement
RTM LAN Card
Two RTM LAN cards are available as below:
●
RTM LAN Card - four LAN Ports
●
RTM LAN Card - two LAN Ports
RTM LAN Card - four LAN Ports
The RTM LAN card routes data between the MPMx/MPMRx cards and components of the system, and
sends media by IP packets and provides connectivity to external IP networks.
Note: MPMx/MPMRx card and RTM LAN card
• An MPMx/MPMRx card on the front of the RMX must always be seated or connected opposite to
either an four ports RTM LAN card 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.
On RMX 4000 systems, RTM LAN cards with four 1Gb ports can be used with the MPMx/MPMRx card(s).
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 MPMx/MPMRx card. In an RMX with a single MPMx/MPMRx
card, the RTM LAN card must be installed in the rear panel slot at the same level as the MPMx/MPMRx card.
On the RMX 4000, LAN port 2 is used to connect the LAN cable. Port 1 is the redundant port*.
Note: Multiple Networks and LAN Redundancy
• * When using an MPMx card with the four ports RTM LAN card, connect the LAN cable to LAN 4.
With Multiple Networks and LAN Redundancy configurations, connect to the LAN 3 port.
• The RTM LAN type card is always required with Multiple Networks and LAN Redundancy
configurations.
Figure below shows the four LAN ports RTM LAN card.
RTM LAN Card - four LAN Ports
Ports on the four ports RTM LAN card are:
● Four 1Gb LAN ports No. 1-4
● One DBG port - Debug port, for internal use.
● ARM/CM - Switch, for internal use.
