Making the LEDs blink

When you have multiple FortiSwitch units and need to locate a specific switch, you can flash all port LEDs on and off for a specified number of minutes.

To identify a specific FortiSwitch unit:
  1. Go to WiFi & Switch Controller > Managed FortiSwitch.
  2. Click on the FortiSwitch unit and then click Diagnostics and Tools.
  3. Select LED Blink > Start and then select 5 minutes, 15 minutes, 30 minutes, or 60 minutes.
  4. After you locate the FortiSwitch unit, select LED Blink > Stop.

NOTE: For the 5xx switches, LED Blink flashes only the SFP port LEDs, instead of all the port LEDs.

Runnng the cable test

You can check the state of cables connected to a specific port. The following pair states are supported:

  • Open
  • Short
  • Ok
  • Open_Short
  • Unknown
  • Crosstalk

If no cable is connected to the specific port, the state is Open, and the cable length is 0 meters.

Using the GUI:
  1. Go to WiFi & Switch Controller > Managed FortiSwitch.
  2. Click on the FortiSwitch unit and then click Diagnostics and Tools.
  3. Select Cable Test.
  4. Select a port.

  • Crosstalk cannot be detected.
  • There is a 5-second delay before results are displayed.
  • The value for the cable length is inaccurate.
  • The results are inaccurate for open and short cables.
