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.

build, 2016/01/04,
Syntax: ledtool <option>
--h := show this help
--list := list leds
--get [--led=led] := get the state of all leds or the specified led
--set <--led=led> [--instance=instance] <--state=state | --
val=value> := set the specified led to the state for color and blink
--test [--config=config_file] := test using the test config file
A list of the LEDs and their states follow the help output.
• list — Provides a list of all the LEDs and their settings.
• test — Testing LEDs is not supported.
• get — Displays the state of the specified LED, or all the LEDs if the parameter is empty.
