Server power-on problems flowchart
Some servers have an internal health LED and an external health LED, while other servers have a single
system health LED. The system health LED provides the same functionality as the two separate internal and
external health LEDs. Depending on the model, the internal health LED and external health LED may either
appear solid or they may flash. Both conditions represent the same symptom.
For the location of server LEDs and information on their statuses, see the server documentation on the HP
website (
