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
To test the LEDs, use the
ledtool --test
command.

DellEmc Diag - Led Tool
version 2.0, x.xx.x.x-x
build, 2019/07/03,
Usage:
List the LEDs:=
ledtool --list
(or)
ledtool -l
Get the state of (specific) LED(s):=
ledtool --get [--led=<led>]
(or)
ledtool -g [-D <led>]
Set the state of specific LED(color and blink):=
ledtool --set --led=<led> [--instance=<instance>] [--state=<state>] [--val=<value>]
(or)
ledtool -s -D <led> [-S <instance>] [-T <state>] [-V <value>]
Execute repeatedly command by count:=
ledtool --iteration=max/<count> [option1] [option2]...
(or)
ledtool -I max/<count> [option1] [option2]...
Give control to CPU:=
ledtool --set --cpu_ctrl
(or)
ledtool -s -U
Give control to FPGA:=
ledtool --set --fpga_ctrl
