Port LEDs
The ports on the PD-Switch include diagnostic LEDs that indicate unique information
about the port functionality and status.
PD-Switch-TX/5
For all units with 5 copper ports, the two LEDs associated with each twisted pair port
are defined as follows:
PD-Switch-TX/3+FX
On units with a 1x9 fiber port, the FDX LED of port 3 has been re-defined as the “FX-
LNK/ACT” LED for the fiber port. Note that the “LNK” LED requires a valid Link
signal and no Far-End-Fault (FEF) from the fiber line.
