Troubleshooting
If the server blade does not start:
1. Be sure that the server blade is fully seated in the server blade enclosure.
2. Verify that power is applied to the server blade enclosure.
3. Be sure that power is applied to the server blade:
a. Check the status using the power on/standby LED. For the location and
explanation of the power on/standby LED, refer to the "Server Blade Front
Panel" section in Appendix E, "LEDs and Switches."
b. Check the server blade management modules and power management
modules for proper cabling and power configuration switch settings.
c. The server blade is configured to power up upon insertion. However, if you
changed that setting, be sure that the Power On/Standby button was pressed
firmly.
NOTE: A long press, 5 or more seconds, initiates a power-up override. The system is forced
to power up the server blade without detecting available power.
4. If the system does not complete POST or start loading an operating system:
a. Use the iLO remote console, the video connection provided through the I/O
cable connectors, or the iLO system status page to identify POST messages.
Refer to the HP Integrated Lights-Out User Guide.
b. Refer to the HP ProLiant Servers Troubleshooting Guide.
5. Ensure the server blade is not rebooting repeatedly:
a. Be sure that the system is not rebooting due to a problem that initiates an
ASR-2 reboot.
ASR-2 is defaulted to restart the server blade automatically, loading the
operating system. If a critical error occurs, ASR-2 logs the error in the IML
and restarts the server blade.
For more information, refer to the HP ProLiant Servers Troubleshooting
Guide.
b. Use the iLO remote console or the video connection provided through the
I/O cable connectors to identify a possible thermal event.
