The link status LED for a cage is:
• Green when both ports for the cage have a physical link.
• Amber when only one port for the cage has a physical link.
Note: This includes when an SFP28 or SFP+ cable is connected, and so only a single port is exposed.
• Off in the absence of any physical link.
• Blinking red if a command such as
ethtool --identify
has been issued to identify the
network port.
The activity LED for a cage is:
• Blinking green when there is link activity on all exposed network ports for the cage.
• Off when there is no activity on any exposed network port for the cage.
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.
