Note: If the Enterasys Matrix N SA 2G4072-52 is being installed in a network using Link
Aggregation, there are rules concerning the network cable and port configurations that
must be followed for Link Aggregation to operate properly. Before connecting the cables,
refer to the Enterasys Matrix N Standalone Series Configuration Guide for the
configuration information. For details on how to obtain manuals, refer to “Related
