Express Ethernet Switch Trouble-shooting Guide This trouble-shooting guide describes problems that could occur with the Express Ethernet Switch. The guide states possible reasons for the problems, and possible steps to take to solve the problems. No Power to the Switch. Symptom: Power cord is connected to the switch, but all LEDs, including the Power LED, are off. -
Page 36: Transmission Problems
Express Ethernet Switch Transmission Problems Symptom: Connections across a LAN switch are slow or unreliable. Possible Solution Problem Express Ethernet Switches are all equipped with auto-negotiation to communicate with other DTEs on the network for the best available performance. Incorrect full- or half-duplex settings Verify if the connected NIC is equipped with auto-negotiation (this is not the same as auto-sensing). -
