Each cage has two adjacent LEDs, showing its link status and its activity.
The link status LED for a cage is:
- Green when a port for the cage has a physical link.
- Off in the absence of any physical link.
- Blinking red if a command such as
ethtool --identifyhas been issued to identify a network port.
The activity LEDs are currently disabled.
Note: Some other LEDs inside the case are visible through
the airflow holes. These internal LEDs are for diagnostic use only, and you should
ignore them.
