Chassis Management Controller Version 2.0 for Dell PowerEdge VRTX User's Guide

Interpreting LED Colors and Blinking Patterns

The LEDs on the chassis provide the following status of a component:

Steadily glowing green LEDs indicate that the component is turned on. If the green LED is blinking, it indicates a critical but routine event, such as a firmware upload, during which the unit is not operational. It does not indicate a fault.
A blinking amber LED on a module indicates a fault on that module.
Blue, blinking LEDs are configurable by the user and used for identification. For more information about configuration, see Configuring LEDs to Identify Components on the Chassis .
