DESCRIPTION
The ADTRAN
®
MX3 4-Port 10/100Base-T Ethernet Module (MX3ETH4) is a plug-in
module for the MX3 Chassis (P/N 1189001L1). The MX3ETH4 Module is deployed with
redundant or non-redundant MX3112 Controller Cards (P/N 1189901L1); however,
redundant MX3ETH4 Modules are not used with the MX3 Chassis. The MX3ETH4 Module
interfaces the MX3112 Controller Card with the four client 10/100Base-T signals.
The MX3ETH4 Module is always installed in module slot
A of the MX3 Chassis.
ETHERNET PORTS
The four Ethernet ports located on the MX3ETH4 Module provide the protection and
physical interface for the MX3112 Controller Card. The ports can be accessed using a
standard CAT 5 cable with an RJ-45 connector. The pin assignments for the RJ-45
connectors are listed in the Ethernet Pin List.
WARNING: The Ethernet Port interfaces MUST NOT be metallically connected to
interfaces that connect to the Outside Plant (OSP) or its wiring. These
interfaces are designed for use as intra-building interfaces only. The
addition of primary protectors is not sufficient protection in order to connect
these interfaces metallically to OSP wiring.
