Tests

You can manually control the front and back panel LEDs, that are normally controlled through the CPLD or FPGA access. When set, bits in these registers control the state of the LED.

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

root@dell-diag-os:/opt/dellemc/diag/bin# ./ledtool --test
LED Test Started... Will take few mins to complete.

DellEmc Diag - Led Tool
version 1.0, x.xx.x.x-x
build, 2022/05/20,

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> [-I <instance>] {-T <state> | -V <value>}
 Execute repeatedly command by count:=
     ledtool --iteration=max/<count> [option1] [option2]...                              (or)
     ledtool -I max/<count> [option1] [option2]...
 Test using config file:=
     ledtool --test [--config=<config_file>]                                             (or)
     ledtool -t [-f <config_file>]

Syntax: ledtool <option>
  -h, --h            Show the help text
  -l, --list         List the LEDs
  -g, --get          Get operation
  -s, --set          Set operation
  -t, --test         Test using the pre-programmed configuration or use supplied config
  -D, --led=         LED
  -I, --iteration=   Iteration command execution
  -S, --instance=,   Instance
  -T, --state=,      State of the LED
  -V, --val=,        Value to be set
  -f, --config=,     To specify the location of the config file e.g. /etc/dn/diag/<file_name>
