4.8  Combo ports 
Characteristics 
Combo port is the name for two communication ports. A combo port has the two 
following jacks: 
•  a fixed RJ-45 port 
•  an SFP transceiver slot that can be equipped individually 
Of these two ports, only one can ever be active. Using the mode, you can decide how the 
ports are prioritized. 
The port name is the same on both jacks of the combo port, for example "PxC". 
There is an LED for each combo port. The LEDs for the combo ports can be identified by 
a vertical line and the word "COMBO". The labeling of the combo port LEDs does not 
differ from that of the other LEDs, e.g. "P3". 
Setting the mode 
The following modes can be configured for a combo port: 
•  Mode 1: auto 
The SFP transceiver port has priority. As soon as an SFP transceiver is plugged in, an 
existing connection at the fixed RJ-45 port is terminated. If no SFC transceiver is 
plugged in, a connection can be established via the fixed RJ-45 port. 
•  Mode 2: rj45 
The fixed RJ-45 port is independent of the SFP transceiver port. 
•  Mode 3: sfp 
The pluggable transceiver port is used independent of the fixed RJ-45 port. 
The factory setting for the combo ports is mode 1: auto 
You configure the mode with Web Based Management or the Command Line Interface.
