Automatic reset in stand-alone operation with warm restart
Note
During Power On with battery backup of a fault-tolerant system with large configurations,
many CPs and/or external DP masters, it may take up to 30 seconds until a requested
restart is executed. During this time, the LEDs on the CPU light up successively as follows:
1. All LEDs light up
2. The STOP LED flashes as it does during a memory reset
3. The RUN and STOP LEDs flash for about 2 seconds
4. The RUN LED flashes briefly 2 to 3 times
5. The STOP LED lights up for about 25 seconds
6. The RUN LED starts flashing again.
This begins the start up.
