Overview… XenaCompact test ports
On the right side of the front panel of the XenaCompact chassis is the test module with its ports. Each test port has a green LED indicating whether the port has achieved basic Ethernet sync with the port it is connected to. Most ports also have a yellow LED indicating that the port is transmitting packets.
The test ports are numbered consecutively, starting from 0 for the left-most port.
For information about the port interface types please see the appropriate test module section.
