The setting of the chosen base configuration can be changed via the “sconf set” command. If
the “sconf set” command is invoked without parameters, all changeable options are shown. In
the following example, first, all possible settings are shown, and then the SerDes port 1 is
changed from rear to the front Ethernet connector J2 (GbE B). In certain “sconf base select”
configurations the ETH front PHY is not available anymore. In such cases it is possible to
switch the AMC SerDes port 1 as copper port to the front panel connector J2 (GbE B).
