The node's LED/LCD indicator is an error status code. Some nodes have a hardware LED/LCD. In this case, the information can be obtained from the Node notebook of the SP Hardware Perspective.
Many LED/LCDs are displayed as status codes during the node boot process. You should be concerned only when an LED/LCD value is displayed for an extended period of time. Values that are specific to the RS/6000 SP System appear in SP-specific LED/LCD values. The hardware manuals for your particular node, and the AIX messages contain the remaining LED/LCD values. See Other LED/LCD codes.
