Revision: 1.0
3.3.2.2
Non-Critical Conditions
A non-critical condition is a threshold crossing associated with the following events:
Chassis intrusion
Critical voltage threshold crossed
Minimum number of fans to cool the system not present or failed
In non-sparing and non-mirroring mode if the threshold of ten correctable errors is
crossed within the window
3.3.2.3
Degraded Conditions
A degraded condition could be associated with the following events:
Unable to use all of the installed memory (more than one DIMM installed).
Correctable errors over a threshold of ten and migrating to a spare DIMM (memory
sparing). This indicates the user no longer has spared DIMMs indicating a redundancy
lost condition. Corresponding DIMM LED should light up.
In mirrored configuration, when memory-mirroring takes place and system loses memory
redundancy. This is not covered by two.
Redundancy loss such as power-supply or fan. This does not apply to non-redundant
sub-systems.
PCI-e* link errors
CPU failure / disabled – if there are two processors and one of them fails
Fan alarm – Fan failure. Number of operational fans should be more than a minimum
number needed to cool the system
Non-critical threshold crossed – Temperature and voltage
3.3.3
Drive Activity LED
The drive activity LED on the front panel indicates drive activity from the onboard hard disk
controllers.
3.3.4
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 light when the System ID button
on the control panel is pressed or it can be illuminated remotely through server management
software.
