HP Fabric HCA Connection LEDs
Normal operation is indicated by solid color logical link LED (green - switch, yellow - HCA),
and a flashing green physical link LED.
The top LED indicates a logical link has taken place. A logical link is established when the subnet
manager makes a sweep, and must be established to use the port.
If the connection from switch port to the corresponding HCA in the remote node is operational,
the "Logical Link" LED shows as solid color (green - switch, yellow - HCA), and the "Physical
Link" LED shows as solid green.
The bottom LED indicates a physical link has occurred. A physical link requires that the drivers
on the attached HP Fabric host have been installed and are running.
If data is flowing between the switch port to the corresponding HCA in the remote node, the
"Logical Link" LED shows as flashing. Note that data does not start to flow until HP Fabric
initialization has occurred.
If either the "Logical Link" or the "Physical Link" LED is off, the HCA is not operational.
