Three boot failure
Configuration changes, such as added devices or adapter firmware updates can cause the server to fail
POST (power-on self-test). If this occurs on three consecutive boot attempts, the server will temporarily use
the default configuration values and automatically goes to F1 Setup. To solve the problem, complete the
following steps:
1. Undo any configuration changes that you made recently and restart the server.
2. Remove any devices that you added recently and restart the server.
3. If the problem remains, go to Setup and select Load Default Settings , and then click Save to restore the
server factory settings.
