User's Manual

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.
