Interpreting LED Colors and Blinking Patterns
The LEDs on the chassis provide information by color and blinking/not
blinking:
• Steadily glowing, green LEDs indicate that the component is powered 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 (see "Configuring LEDs to Identify Components on the
Chassis" on page 401).
