SFS 7024 Leaf and Spine Module LEDs

Leaf Module IB Port LEDs

Each SFS 7024 leaf module port has a Blue IB link status LED that provide the following indications:
• On - the logical link is up (port is in the Active state).
• Slow Blink - the physical link is up (port is in the Initialization state).
• Fast Blink - IB data is flowing through the port.
• Off - the physical link is down (port is in the Down state).

Spine and Leaf Module Status LED

The status LED indicates one of the following conditi ons:
• Steady Green - the module is operating normally.
• Blinking Green (twice per second) - transitioning to the removal state.
