Table 52. CMM Health LED States

Color	Description
Off	No power to CMM
Solid Green	Normal operation, power okay
Blinking Green	CMM in standby mode
Solid Red	Attention status (CMM is unhealthy due to critical power error)

12.1.3Hot Swap LED

Each CMM maintains a single blue hot swap LED (ÝÜ) to provide the status of the CMM itself. The hotswap LED cannot have its state set or changed and is readable only.

Table 53. CMM Hot Swap LED States

Color	Description
Off	In use
Long Blink	Searching for CMM (900ms on, 100ms off)
Solid Blue	Ready to remove
Short Blink	Preparing for extraction (100ms on, 900ms off)

12.1.4User Definable LEDs

Each CMM provides four LEDs (A, B, C, D on the front panel and userled [1, 2, 3, 4] in the CLI, respectively) that can be controlled via the CMM. Each LED can be off, green, yellow, or red.

During the boot process the user LEDs sequentially blink off to indicate boot progress. The user LEDs will be off by the time the CMM software is fully loaded. Once the CMM is up, the administrator can control the LED through standard interfaces or via programmatic control.

12.2Retrieving a Location’s LED properties

The properties for a location’s LED control status and the number of User LEDs a location supports can be retrieved using the command:

cmmget -l [location] -d ledproperties

12.3Retrieving Color Properties of LEDs

The valid colors that an LED supports and the default color properties for that LED can be retrieved using the command:

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