I have a question on the switching hub (HPE 1420 16G).
The panel was connected to the switching hub (HPE 1420), and the network was confirmed with the following three patterns.
· Auto negotiation ON Communication speed: 10 Mbps
· Auto negotiation ON Communication speed: 100 Mbps
· Auto-negotiation ON Communication speed: 1 Gbps
Network connection / disconnection occurs repeatedly only when the communication speed setting is 100 Mbps.
Is there a solution?
