Chapter 3 Troubleshooting This chapter contains information on how to troubleshoot the switch if a problem occurs. Note For further assistance, please contact Allied Telesis Technical Support at www.alliedtelesis.com/support. Problem 1: The POWER LED on the front of the switch is off. Solutions: The unit is not receiving power. Try the following: Verify that the power cord is securely connected to the power source and to the AC connector on the back panel of the switch.
Chapter 3: Troubleshooting Try connecting another network device to the twisted pair port with a different cable. If the twisted pair port is able to establish a link, then the problem is with the cable or the other network device. Verify that the twisted pair cable does not exceed 100 meters (328 feet). Verify that you are using the appropriate category of twisted pair cable: Category 3 or better for 10 Mbps operation and Category 5 and Category 5E for 100 and 1000 Mbps operation.
Solution: There might be a duplex mode mismatch between the port and the network device. This occurs when a twisted pair port using AutoNegotiation is connected to a device with a fixed duplex mode of full duplex. If this is the cause of the problem, adjust the duplex mode of the port on the network device or on the switch so that both ports are using the same duplex mode. Problem 6: A port’s LINK/ACT LED is blinking. Solutions: The link between the port and the network device is intermittent.
