3.2. Simple testing
3.2.1. Self-examination
When connection equipment, the front panel power supply indicator light
will blinking once, it means working well. After a while Power supply indicator
light is on. Run indicator light (system status LED) will blink interval 1s.
3.2.2. Copper port testing
As below picture. Powering on the switch, connect any two copper ports to
the network ports of the two test computers through the direct connection
network cable, and send ping commands to each other. Both parties can
correctly ping each other without losing packets. At the same time, the yellow
light on the corresponding port should be always on (the computer network
card works in the 100M state) or often off (the computer network card works in
the 10M state), and the green light on the corresponding port should flash. The
hardware of the two electrical ports tested is working properly. The following
test diagram takes the 8-port product of the MIEN5208 series switch as an
example.
3.2.3. Fiber testing
The device with the fiber interface is composed of the fiber chain network
shown in Figure 3-5 (TX is connected to another RX, and RX is connected to
another TX). Each of the copper interfaces of each device is connected to the
test computer through a direct-connected network cable and sends ping
commands to each other. Both parties can correctly ping each other without
losing packets. At the same time, the LINK lamp corresponding to the optical
