Troubleshooting 72
Always use the recommended minimum configuration above before removing any processors. If you are
unable to isolate the issue with the configuration above, you will then remove all all but one of the additional
processors.
CAUTION:
Before removing or replacing any processors, be sure to follow the guidelines
provided in "Performing processor procedures in the troubleshooting process (on page
)."
Failure to follow the recommended guidelines can cause damage to the system board, requiring
replacement of the system board.
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
components.
•
Remove and check all data and power cables for damage. Be sure no cables have bent pins or
damaged connectors.
•
If a fixed cable tray is available for the server, be sure the cords and cables connected to the server are
routed correctly through the tray.
•
Be sure each device is properly seated. Avoid bending or flexing circuit boards when reseating
components.
•
If a device has latches, be sure they are completely closed and locked.
•
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.
Service notifications
To view the latest service notifications, refer to the HP website
. Select
the appropriate server model, and then click the Troubleshoot a Problem link on the product page.
Server health LEDs
Some server blades have an internal health LED and an external health LED, while other server blades 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 blade LEDs and information on their statuses, see the server blade documentation
