Management Cables
Out-of-band management communication is connected to an XDM-300 by
means of a minihub with a pair of the RJ-45 Ethernet connectors located on the
ECU300-F and ECU300 cards.
If one XDM-300 is installed, the connection is made to the management MAIN
RJ-45 connector. If more than one XDM-300 is installed in the same site, it is
possible to save the use of an external hub. In this case, the first system is
connected as explained above, and the other systems are connected in an
Ethernet daisy chain. The management MAIN connector of each system is
connected to the management PROT/LCT connector of the previous system.
Suitable standard Ethernet station cables are available from many sources.
Cables of Category 3 or better must be used. The length of the cables must not
exceed the maximum recommended for the cable type and hub port in use (up
to a few dozen meters).
