4.2.2.1
Critical Conditions
A critical condition is any critical or non-recoverable threshold crossing associated with the
following events:
•
Temperature, voltage, or fan critical threshold crossing.
•
Power subsystem failure. The BMC asserts this failure whenever it detects a power
control fault (e.g., the BMC detects that the system power is remaining ON even though
the BMC has deserted the signal to turn off power to the system.
•
A hot-swap backplane would use the Set Fault Indication command to indicate when one
or more of the drive fault status LEDs are asserted on the hot-swap backplane.
•
The system is unable to power up due to incorrectly installed processor(s), or processor
incompatibility.
•
Satellite controller sends a critical or non-recoverable state, via the Set Fault Indication
command to the BMC.
•
Critical event logging errors, including: System Memory Uncorrectable ECC error, and
fatal / uncorrectable bus errors such as PCI SERR and PERR.
4.2.2.2
Non-Critical Conditions
A non-critical condition is threshold crossing associated with the following events:
•
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.
•
Set Fault Indication command from system BIOS. The BIOS may use the Set Fault
Indication command to indicate additional 'non-critical' status such as a system memory
or CPU configuration changes.
4.2.2.3
Degraded Conditions
A degraded condition is associated with the following events:
•
Non-redundant power supply operation. This applies only when the BMC is configured
for a redundant power subsystem.
•
One or more processors are disabled by Fault Reliant Booting (FRB) or BIOS.
•
BIOS has disabled or mapped out some of the system memory.
4.2.3
Drive Activity LED
The drive activity LED on the front panel indicates drive activity from the onboard hard disk
controllers. The server board SE7221BK1-E also provides a header giving access to this LED
for add-in controllers.
4.2.4
System Identification LED
The blue system identification LED is used to help identify a system for servicing. This is
especially useful when the system is installed when in a high density rack or cabinet that is
populated with several similar systems. The system ID LED will blink when the System ID
button on the control panel is pressed or it can be illuminated remotely through server
management software.
