The MA-230 module adapter has two Ethernet ports, LAN and WAN. Both ports have these
capabilities:
●
Support full-duplex and half-duplex operation
●
Can operate at 100 Mbps and 10 Mbps
●
Support auto-negotiation of interface rate and duplex
You can set each Ethernet port to operate independently. The LAN port provisioning default is auto-
negotiation. The WAN port provisioning default is 100 Mbps, full-duplex operation. The WAN port can
transport customer side traffic to/from the LAN interface and TDM interfaces to the network. When
connected to your LAN, the NetXpress LX system can carry packet data to or from the WAN based on
static routing rules in the CM-30R common module.
The WAN and LAN ports have indicator lights for 10 Mbps and 100 Mbps activity. Figure 3-5 shows the
port indicator light positions.

Systems with redundant CM-30R controllers will use the MA-231-1 and MA-231-2. Using this module
adapter pair provides for two independent WAN and LAN ports for the network connection.

Note:
The MA-
230 module adapter’s RJ45 connector is not intended to be connected
directly to
telecommunication networks.
3.2.2.4 MA-230 and CM-30R Module Installation and Connection
The MA-230 module adapter is installed in the slot matching the CM-30R module on the back panel of
the NetXpress LX chassis and connects with the CM-30R IP interface module at the midplane (Figure
3-6).
