ETHERNET Connectors
The two ETHERNET connectors located on the ECU300/ECU300-F panel,
designated MANAGEMENT MAIN and PROT/LCT, are 8-pin RJ-45
connectors that provide two Ethernet 10BaseT management interfaces (one for
each MXC300 card installed in the XDM-300 shelf).
At any time, only the interface connected to the MXC300 serving as the current
main card is active; the interface connected to the MXC300 serving as the
protection card is in standby to provide protection for the out-of-band
management traffic.
Each ETHERNET connector is wired as a station port intended for direct
connection through a straight cable to a port of a 10BaseT Ethernet hub.
The following figure identifies the connector pins as seen when looking into
the connector. The table lists the pin assignment for a typical connector.
