Non-Critical Condition
A non-critical condition indicates that at least one of the following conditions is present:
• Temperature, voltage, or fan non-critical threshold crossing.
• Chassis intrusion.
• Satellite controller sends a non-critical state, via the Set Fault Indication command, to the BMC.
• A Set Fault Indication command from the system BIOS. The BIOS may use the Set Fault Indication command to
indicate additional, non-critical status such as system memory or CPU configuration changes.
Degraded Condition
A degraded condition indicates that at least one of the following conditions is present:
• A processor is disabled by FRB or BIOS.
• BIOS has disabled or mapped out some of the system memory.
Refer to the Sun Cobalt LX50 server Troubleshooting Guide for information on how to isolate the server component
responsible for any of the critical, non-critical or degraded conditions listed above.
