Unhappy cRIO completely unresponsive

Hello CD,

After our regional, we did a demonstration at our school, during which the robot's battery voltage dropped to 10 volts.

The next day I came to unplug the batteries from the chargers, and check up on the robot. However, I discovered that the robot was completely unresponsive. (no robot comms, or code).

The first thing I did was check the Dlink. I could ping the Dlink, but not the cRIO. So the Dlink was OK.

I then connected a laptop (with the firewall/antivirus disabled) to the cRIO (via crossover on port 1). However, the imaging tool couldn't see the cRIO, and I couldn't ping the cRIO either. The reset button on the cRIO didn't help either. Something else strange was that the green light on the second Ethernet port was constantly lit (even when there was nothing in the port).

I checked for metal shavings, dirt, grease, anything that could interfere with the operation with the cRIO.

Can anyone give any suggestions? Should I contact NI and ask for help? If I call NI, what information do I need? (The service tags on the bottom of our cRIO were ripped off in a previous season).

Thanks in advance,
Daniel
