The SHMC or higher level software can reject the request to move to the M6 state. If this occurs, the RTM will
return the Hot Swap LED to a solid off condition, indicating that the RTM has returned to M4 state.
If the RTM reaches the M6 state through an extraction request from the RTM handle latch, the MMC
communicates to the front board that the module must discontinue operation in preparation for removal. The
Hot Swap LED continues to flash during this preparation time, just like it does at the M5 state. When main
RTM payload power is successfully removed from the RTM slot, the Hot Swap LED remains lit, indicating it is
safe to remove the RTM from the chassis or the hard disk from the RTM.
Refer to the AT8940 manual for information on "Managed FRU Deactivation Policies" affecting the FRU
deactivation process.

All LEDs can be overriden with standard PICMG LED APIs
2.8.1 Hot Swap LED (LED0)

operation, the OOS LED is OFF. This LED is ON during firmware upgrade and is user configurable if needed by a
customer application.
2.8.3 Healthy LED (LED2)
The AdvancedTCA LED2 is green or amber and indicates a healthy condition. The healthy LED indicates if the
blade is powered up and all voltages and temperatures are within specifications. During normal operation,
this LED is ON (green). This LED is also ON (amber) when one of the RTM8940 voltage or temperature sensor
pass a threshold.
2.8.4 QSFP+, SFP+ and SFP LED
The Green LEDs indicate the link status of the connection. The LED is ON when there is a link otherwise, it’s
OFF.
