RTM LAN Card - two 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: RTM LAN card with two LAN ports
• An MPMx/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.
On RMX 4000 systems, RTM LAN cards with two 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.
The RTM LAN card with two LAN ports is shown next.

DC Power Entry Module (PEM)
A DC PEM includes a power inlet, circuit breaker, EMI filter and backplane connectors. Power input to the
system is fed via a power rail through backplane into the power supply. Each DC PEM has its own dedicated
power cable. The circuit switch on the rear of the RMX activates independently any PEM installed on the
RMX. A DC system has two DC PEMs, one for each power rail.
