Both the RJ-45 connector and the LC connector (SFP module) cannot be used as Gigabit Ethernet
port at the same time. For example, if a RJ-45 connector of 10/100/1000Base-T port is connected
to a Gigabit Ethernet device, a LC connector of SFP port is automatically disabled.
The following table lists the specifications of the Gigabit Ethernet port on the OPT-N2CS
module:
