Service notifications

To view the latest service notifications, refer to the HP website (http://www.hp.com/go/bizsupport). Select
the appropriate server model, and then click the Troubleshoot a Problem link on the product page.

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).

Troubleshooting flowcharts

To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page 107)," and follow the appropriate diagnostic path. If the other
flowcharts do not provide a troubleshooting solution, follow the diagnostic steps in "General diagnosis
flowchart (on page 108)." The General diagnosis flowchart is a generic troubleshooting process to be used
when the problem is not server-specific or is not easily categorized into the other flowcharts.
The available flowcharts include:
•
