If the server does not start:
1. Be sure that the server and monitor are plugged into working outlets.
2. Be sure that the power source is working properly:
a. Check the status using the Power On/Standby LED. For the location and
explanation of the Power On/Standby LED, refer to "Front Panel LEDs" in
Appendix E.
b. Be sure that the Power On/Standby button was pressed firmly.
Refer to the Servers Troubleshooting Guide for details on power sources and
what else to check.
3. Be sure that the power supplies are working properly.
a. Check the status using the power supply LEDs. For the location and
explanation of these LEDs, refer to "Hot-Plug Power Supply LEDs" in
Appendix E.
b. Also refer to the Servers Troubleshooting Guide for information about power
sources.
4. If the server does not complete POST or start loading an operating system, refer
to the Servers Troubleshooting Guide for information about general loose
connections.
5. If the server is rebooting repeatedly, be sure that the server is not rebooting
because of a problem that initiates an Automatic Server Recovery-2 (ASR-2)
reboot.
You can enable ASR-2 to restart the server and automatically load the operating
system. Should a critical error occur, ASR-2 logs the error in the IML and
restarts the server.
For more information about ASR-2 and other reasons for repeated booting, refer
to the Servers Troubleshooting Guide.
6. Restart the server.
IMPORTANT: If the server does not restart, proceed to "Diagnostic Steps" in this
