  If the power LED on your Allied Telesis Network Router is off, it means the unit isn't receiving power. First, check that the power cord is securely connected both to the power source and to the AC connector on the back of the switch. Then, make sure the power outlet works by plugging another device into it. Try connecting the unit to a different power source and using a different power cord. Also, verify that the voltage from the power source is within the required levels for your region.

  If the LINK/ACT LED is off on a twisted pair port of your Allied Telesis Network Router, the port likely can't establish a link. First, ensure the connected network device is powered on and working correctly. Check that the twisted pair cable is securely connected to both the port on the media converter channel and the port on the remote network device. Verify you're using the correct twisted pair cable to connect to the right network device. Try connecting another network device to the port with a different cable to rule out cable issues. Confirm the twisted pair cable doesn't exceed 100 meters (328 feet). Also, ensure you're using the appropriate category of twisted pair cable: Category 3 or better for 10 Mbps, and Category 5 or 5E for 100 and 1000 Mbps.

What does a blinking LINK/ACT LED on my Allied Telesis AT-GS950/48PS mean?

  Angela CrawfordAug 18, 2025
  A blinking LINK/ACT LED on your Allied Telesis Network Router indicates an intermittent link between the port and the network device. To resolve this: * Connect another network device with a different cable to the port. If the Link LED remains steady, the problem is with the original cable or network device. * If the problem is with an SFP transceiver, check that the transceiver is fully inserted in the slot.

Why is the network performance slow on my Allied Telesis AT-GS950/48PS Network Router twisted pair port?
- K
  Kristin WhiteAug 25, 2025
  Slow network performance between a twisted pair port and a network device on your Allied Telesis Network Router could be due to a duplex mode mismatch. Adjust the duplex mode of the port on the network device or on the switch, ensuring both ports use the same duplex mode.

  If the LINK/ACT LED for an SFP transceiver on your Allied Telesis Network Router is off, the fiber optic port likely can't establish a link. First, verify that the connected network device is operating correctly. Check that the fiber optic cable is securely connected to both the port on the media converter channel and the port on the remote network device. Ensure the SFP module is fully inserted in the slot. Verify the operating specifications of the fiber optic ports on both the SFP transceiver and the remote network device are compatible, and that you're using the correct type of fiber optic cabling. Ensure the port is connected to the right fiber optic cable and the correct remote network device. Try connecting another network device to the fiber optic port with a different cable. Use t...
