the fiber interface uses LC interface. The fiber interface needs to be used in
pairs (TX and RX are a pair), the TX port is the optical transmitter, and the
optical transceiver RX of the optical interface of another remote switch is
connected, the RX port is the optical transceiver, and the same optical
interface is connected to the same remote switch. The light ends TX. The two
redundant 1000Base-LX fiber interfaces can be used to form a fiber redundant
ring network. When the system fails, the ring network redundancy switching
time is less than 20ms, which can effectively improve the reliability of network
operation.

Power input terminal
The standard configuration of this series of switches uses 24V DC power
supply, and the power input is connected with 5.08mm pitch terminals, as
shown in Figure 2-3. The power consumption of the whole machine is less than
15W.
