System range of modules together with their function and status.
4.1 8000 SERIES TMR PROCESSOR
LED INDICATION
Healthy Overall health of each processor slice:
Steady
= healthy
Red flashing = slice failed.
Active Steady green when module is in Active mode.
Standby Steady green when module is in Standby mode.
Flashing green when module has changed from Active to
Standby mode.
Educated Steady green when module is educated.
Flashing green when being educated.
Off when module is not educated, or application is stopped.
Run Flashing green when module is in normal operation with full
integrity.
Steady green in standby.
Off when the application in the Active Processor is stopped.
Inhibit Flashing green when any input or output is locked.
This LED also flashes green if a changeover from Active to
Standby is attempted when the current Standby Processor has
incompatible system configuration.
System Healthy System health:
Steady green
= healthy
Flashing red = system boot-up, system fault, or self-test
fail, IMB error, or 8000 Series I/O module error.
Active/standby module failing to respond,
has a slice error, channel fault, or a module
is being simulated. Regent I/O module error. A module is
failing to respond.
Off = illegal state
User 1 and User 2 General purpose red LEDs for use under software control.
Note: If the Healthy LED is green flashing and power is switched off, then on again, the
faulty slice may fail to operate again. When the Healthy LED is flashing red,
processing is automatically switched to the standby Processor.
