When you have multiple FortiSwitch units and need to locate a specific switch, use the following command to flash all port LEDs on and off for a specified number of minutes:
diagnose switch physical-ports led-flash <disable | time>
You can flash the port LEDs for 5, 15, 30, or 60 minutes. After you locate the FortiSwitch unit, you can use
disable to stop the LEDs from flashing.
NOTE: For the FS-5xx switches, the
diagnose switch physical-ports led-flash command flashes only the SFP port LEDs, instead of all the port LEDs.
