1. Il computer è connesso ad altri dispositivi tramite lo switch e si trova sullo stesso segmento di rete, ma il Ping è bloccato. Quale sarà il problema??

Hardware failure: check whether the display light, power supply and connection of the switch are normal, and whether the switch is normal
Setting failure: 1. Check whether the switch is set. If an IP address that is not in the same network segment as other devices is set, delete it or set an IP address that is in the same network segment as other devices. 2. Failure of VLAN setting. Several ports connected to the switch belong to different VLANs, so they are blocked. Remove or modify the set VLAN to the same VLAN.
