Network controller is installed but not working
Action:
1. Check the network controller LEDs to see if any statuses indicate the source
of the problem. For LED information, refer to the network controller
documentation.
2. Be sure no loose connections (on page 154
) exist.
3. Be sure the network cable is working by replacing it with a known functional
cable.
4. Be sure a software problem has not caused failure. Refer to the operating
system documentation for guidelines on adding or replacing PCI Hot Plug
devices, if applicable.
5. Be sure the server and operating system support the controller. Refer to the
server and operating system documentation.
6. Be sure the controller is enabled in RBSU.
7. Check the PCI Hot Plug power LED to be sure the PCI slot is receiving
power, if applicable.
8. Be sure the server ROM is up to date.
9. Be sure the controller drivers are up to date.
10. Be sure a valid IP address is assigned to the controller and that the
configuration settings are correct.
11. Run Insight Diagnostics ("HP Insight Diagnostics" on page 126
) and replace
failed components as indicated.
