3.2.9 Ledtool
ledtool
The ledtool allows you to control the state of the front and back panel light emitting diodes (LEDs). ASIC and Phys control
the port LEDs and are beyond the scope of this tool.
You can manually control the front and back panel LEDs normally controlled through the CPLD or FPGA access. When set, bits
in these registers control the state of the LED.
Tests
Use the ledtool --test command to test the LEDs.
root@dell-diag-os:/opt/ngos/bin# ./ledtool --test
LED Test Started... Will take few mins to complete.
