LED Color, Behavior, and Meaning

The following sections explain the possible colors and the corresponding meaning of the various LEDs on the HP Fabric HCA and switches.

HP Fabric Switch Cluster Connection LEDs

Normal operation is indicated by solid color logical link LED.

If the connection from switch port to the corresponding HCA in the remote node is operational, the LED shows as solid color. A physical link requires that the drivers on the attached HP Fabric host have been installed and are running.

If the HCA is not operational and needs to be replaced, see “Install HP Fabric Clustering System Adapters” (page 36).
