1.2 successful site switching

2, Pig house sound monitor

2.1 how to maintain the voice offline equipment display in the processing area when it is not online

Tools: off-line pig house sound monitor, network cable, Xinrui 45pcs precision screwdriver-S2, network cable pliers

Open the four sealants at the bottom of the equipment with tools, twist the screws, continue to connect the equipment and the switch with the network cable, and observe that the equipment is disassembled. The red light at the large end is always on, the green light flashes, and the LED1 red light at the small end is always on, and the LED7 and LED10 green lights flash.

2. Connect with the background to see if the equipment is plugged into the switch (the switch can be connected to the external network), and send the two-dimensional code of the test equipment to the background to determine whether the equipment is online?

The equipment is normal

The equipment is abnormal: the switch light is not on, there is a problem, and it is normal to remove the light. There may be a problem with the tail cable of the equipment. Open the equipment, take out the motherboard, clean the glue on it, press the crystal head in the large end of the equipment with network cable pliers, and reinstall it.
