Loose connections
Action:
•
Be sure all power cords are securely connected.
•
Be sure all cables are properly aligned and securely connected for all external and internal

Check any interlock or interconnect LEDs that may indicate a component is not connected properly.
•
If problems continue to occur, remove and reinstall each device, checking the connectors and sockets
for bent pins or other damage.

Server health LEDs
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 (http://www.hp.com/support).
