CPUs are mismatched.

 

 

 

At least one CPU is faulty.

 

 

 

At least one DIMM is faulty.

 

 

 

At least one drive in a RAID configuration failed.

 

 

Amber, blinking—The server is in a critical fault state. For example:

 

 

 

Boot failed.

 

 

 

Fatal CPU and/or bus error is detected.

 

 

 

Server is in an over-temperature condition.
