Note:
The optical and electrical interfaces of 10/100/1000 Mbps Ethernet cannot be used together. In
GE (E/F), E indicates electrical interface and F indicates optical interface. In the optical and
electrical interfaces, one can be used. The electrical interface on the main control board can be
used directly, which is RJ45. The optical port can be used after the SFP module is configured.
When both cable and fiber are connected, only the electrical interface can work.
