12.4Retrieving the State of LEDs

The state of an LED on a location can be retrieved using the command:

cmmget -l [location] -t [LED] -d ledstate

12.5Setting the State of the User LEDs

The state of the User LEDs on the CMM or other FRUs can be changed using the ledstate set command. Here is the syntax and the table below lists the function values and options:

cmmset -l [location] -t [LED] -d ledstate -v [function],[function options]

Example:

cmmset -l cmm -t “userled1” -d ledstate -v blink,300,700,green

This sets the CMM’s user1 LED to blinking green with an off duration of 300 ms and an on duration of 700 ms. The following table list functions that can be used when setting the state of LEDs:

The all_leds target can also be used to set all User LEDs on the FRU to the specified value(s). For example, to set all four user LEDs to ‘on’ and the color ‘green’ use the following command:

cmmset -l cmm -t 'all_leds' -d ledstate -v on,green

Note: The ledstate dataitem on the all_leds target is a set-only item. Doing a cmmget -d ledstate on all_leds target will return an error.

Table 54. Ledstate Functions and Function Options

[function] values	description	[function options]
off	Turns the target LED(s) off.	no options
on	Turns the target LED(s) on.	[color]
blink	Makes the target LED(s)	[offtime],[ontime],[color]
	blink at the specified rate.
lamptest	Puts the target LED(s) into	[duration],[color]
	lamp test mode for the
	specified time.
localcontrol	Puts the target LED(s) back	no options
	into normal operation.

The following are possible values for function options:

•color = one of blue, red, green, amber, orange, white, default, nochange

•offtime = the time in milliseconds that the LED is in the off cycle of a blink. Granularity=10 ms Min=10 ms Max=2500 ms

•ontime = the time in milliseconds that the LED is in the on cycle of a blink. Granularity=10 ms Min=10 ms Max=2500 ms

•duration = the duration of the lamp test in milliseconds. Granularity=100 ms Min=100 ms Max=12700 ms
