(which includes the Major, Minor, and Warning alarms) reflects maintenance conditions in the entire
system.
• Red (alarm) – The system has detected a fault in this circuit pack.
NOTE:
Alarms on the PROCR, PR-MAINT, SW-CTL, and PKT-INT maintenance objects are
indicated by the red LED on the Processor circuit pack.
• Green (test) – The system is running tests on this circuit pack.
• Amber – In an operating system, this LED indicates that the handshaking between the firmware
