Notes:
1. The BIOS detects these conditions and sends a Set Faul tegrated BMC to provide
the contribution to the stem
2. Support for upper non-critical limit is not provided in the default SDR configuration. However, if a user does
enable this threshold in the SDR, then the system status ibed.
There is no precedence or lock-out mechanism for the control sources. When a new request
arrives, all previous requests are terminated. For example, if the chassis ID LED is blinking and
the chassis ID button is pressed, then the chassis ID LED changes to solid on. If the button is
pressed again with no intervening commands, the chassis ID LED turns off.
