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.

Running the cable test

NOTE: Running cable diagnostics on a port that has the link up interrupts the traffic for several seconds.

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.
5. Select Diagnose.

NOTE: There are some limitations for cable diagnostics on the FS-108E, FS-124E, FS-108E-POE, FS-108E-FPOE, FS-124E-POE, FS-124E-FPOE, FS-148E, and FS-148E-POE models:

• 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.
