Intel MPCMM0001 Front Panel LEDs, LED Types and States, Alarm LEDs, System Health LED States

	Front Panel LEDs
Front Panel LEDs	12

The CMM has nine LEDs on the front panel of each unit for displaying system health, hot swap state, and other information. They include:

•Three system health LEDs

•One CMM Health LED

•One CMM HotSwap State LED

•Four User-Definable LEDs (A-D)

For more information on CMM LEDs refer to the Intel® NetStructure™ MPCMM0001 Hardware Technical Product Specification.

12.1LED Types and States

The CMM can retrieve and, in some cases, set values for LEDs on the CMM, fan trays, PEMs, and blades in the chassis. Refer to Section 8, “The Command Line Interface (CLI)” on page 71 for more information. The following tables list the default values for the LEDs on the CMM. Other locations will likely have different LED properties that can be retrieved through the CMM.

12.1.1Alarm LEDs

There are three alarm LEDs on the CMM corresponding to the minor (!), major (!!) and critical (!!!) alarm states. The LEDs are amber when on. Each LED has the following meaning:

Table 51. System Health LED States

LED (Symbol)	Status	Description
Minor Alarm	Off	No Minor Alarm active
	On	Minor Alarm active
(!)
	Flashing	Minor Alarm active, but silenced
Major Alarm	Off	No Major Alarm active
	On	Major Alarm active
(!!)
	Flashing	Major Alarm active, but silenced
Critical Alarm	Off	No Critical Alarm active
	On	Critical Alarm active
(!!!)
	Flashing	Critical Alarm active, but silenced

The Alarm LEDs on the CMM can be turned on or off using the minorled, majorled, and criticalled CMM dataitems. This also affects the relay contacts. The value is 1 or 0. For example, the command to turn the criticalled off is:

cmmset -d criticalled -v 0
