Intel SC5400LX User Manual

A non-critical condition is a threshold crossing associated with the following events: 

ƒ 

Chassis intrusion 

ƒ 

Critical voltage threshold crossed 

ƒ 

Minimum number of fans to cool the system not present or failed 

ƒ 

In non-sparing and non-mirroring mode if the threshold of ten correctable errors is 
crossed within the window 

 

A degraded condition could be associated with the following events: 

ƒ 

Unable to use all of the installed memory (more than one DIMM installed). 

ƒ 

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. 

ƒ 

In mirrored configuration, when memory-mirroring takes place and system loses memory 
redundancy. This is not covered by two. 

ƒ 

Redundancy loss such as power-supply or fan. This does not apply to non-redundant 
sub-systems. 

ƒ 

PCI-e* link errors 

ƒ 

CPU failure / disabled – if there are two processors and one of them fails 

ƒ 

Fan alarm – Fan failure. Number of operational fans should be more than a minimum 
number needed to cool the system 

ƒ 

Non-critical threshold crossed – Temperature and voltage

 

The drive activity LED on the front panel indicates drive activity from the onboard hard disk 
controllers.  

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.
