Hi guys:
Please help me with IRB1400 S4C
I'm having problems after disconnecting the backup battery to measure its voltage (after having low battery message). It was okay 25v.
Then I saw that the small battery of the cpu (3V) was dead. I changed it.
After this the system is no longer booting, and the red status LED blinks in the CPU.
In the TPU the message "Wait Startup in progress" is displayed infinitely.
In the power supply the LED is off even though the AC and DC output are measured and ok
Before disconnecting the battery and having this problem the boot occurred normally and the system requested for the last backup image saved and properly initialized the controller.
Questions:
Disconnecting the battery may interfere with the boot?
If yes what happens and what it is necessary to do so that the boot is realized?
Is there any special procedure after reconnecting the batteries, such as jumping and or handling any signal?
Thanks in advance
