      Carlos CollinsAug 11, 2025
      If the Link LED is OFF on your i3 International Switch, there are several things to check: * First, verify that both the switch and the devices connected to it are powered on. * Ensure that the cable is securely plugged into both the switch and the corresponding device. * If the switch is in a rack, inspect the connections to the punch-down block and patch panel. * Confirm that you are using the correct cable types and that their length does not exceed the specified limits. * Finally, check the adapter on the attached device and the cable connections for any defects, and replace any defective components.

      Slow file transfer or performance degradation on your i3 International Switch can occur if the attached device is not set to auto-negotiate. Ensure that the attached device is set to auto negotiate and that both the port and the device are on the same setting (Auto, Half, or Full Duplex).
