MIEN2208 Series Unmanaged Industrial Ethernet Switch

each other without packet loss. At the same time, the yellow light on the

corresponding port should be always on (the computer network card works in

100M state) or off (the computer network card works in 10M state), and the

green light on the corresponding port should flash. It means that the hardware

of the tested two copper ports is working normally. The following test diagram

takes the 8 copper port products of MIEN2208 series switches as an example.

3.3.3. Fiber port testing

The equipment with optical fiber interface is formed into the optical fiber

chain network as shown in below (TX connects to another RX, RX connects to

another TX). Each copper port of each device is connected to the test

computer through a directly connected network cable, and sends Ping

commands to each other, so that both parties can correctly ping each other

without packet loss. At the same time, the LINK light corresponding to the

optical port should flash, indicating that the hardware of the two optical ports

under test is working properly. Below is a schematic diagram of the optical port

test using the 2 fiber 6 copper switch in MIEN2208 series switches as an

example.
