Note: When you restart the BCM450 system using the Reset button, the system will wait for 10 seconds for a user to log into the Maintenance CLI. If a user does not log in during that time period, the BCM450 will reboot to the Main OS.

Power on self test

The power on self test (POST) feature tests basic hardware functionality when the BCM450 system powers up, and stores the results in a log file. You can view the log file for hardware failures.

Viewing the POST log file

1Use Element Manager to transfer the log files to your PC. Refer to the “BCM450 Log management” chapter in the BCM450 Administration and Security Guide (NN40160-601) for information about how to transfer log files.

2View the bootloader.log file.

3Check the log file for errors. Figure 5 on page 28 shows a bootloader.log file with no errors; Figure 6 on page 28 shows a file with errors.
