A single clock source triggers an alarm that can be turned off by setting the appropriate flag
in the system configuration.
RTM LAN
The RTM LAN card routes data between the MPM+/MPMx cards and components of the
system, sends media by IP packets and provides connectivity to external networks.
An RTM LAN card must connect directly to an MPM+/MPMx card. In an RMX with a
single MPM+/MPMx card, the RTM LAN card must be installed in the rear panel slot on the
same level as the MPM+/MPMx card.
Each RTM LAN card includes two LAN ports and a maximum of four RTM LAN cards can
be installed on the RMX 4000.

AC Power Entry Module (PEM)
An AC PEM includes a power inlet, EMI filter and backplane connectors. Power input to the
system is fed via a PEM (Power Entry Module) through backplane into the power supply.
Each AC power module has its own dedicated power cable. The ON/OFF switch on the rear
of the RMX activates any power module installed on the RMX. An AC system has three AC
PEMs, one for each power module. On failure, both AC power supplies and PEMs are hot
swappable.
DC Power Rail Module
A DC power rail module 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 power rail has its own dedicated power cable. The circuit switch on
the rear of the RMX activates independently any power rail installed on the RMX. An DC
system has two DC rails, one for each power rail. On failure, a DC power rail is field
replaceable and the RMX must be switched OFF from the two circuit switches and the
mains.
