Thanks for letting me know.  Just out of curiosity - is the firmware between the 832 and 832A the same or different?

Nothing connected at all - ie: The power cable was the only cable coming from the unit. No channels were turned on. The PSU had been running for about 3 Minutes at the time from a completely cold start. That was about a 6 Months ago and has never happened since.

My reset issue just occurred again. I was working on something else and heard the fans ramp to full speed like it does on power up, and noticed the outputs were off. They were on previously, but with no load...

Very odd. Thinking I might contact Rigol about this.

I have a weird issue with a DP832A and it's ethernet port and would be interesting if anyone else has issues?

When in DHCP mode, regardless of the lease duration set on the server, the DP832A requests a new IP every 5 minutes.  So it seems to be ignoring the lease duration, although this could be linked to...

Every so often the supply will drop off the network, either a reboot or a reset of the IP parameters via the front panel will fix this.  Also the display will display the LAN connected message at power up OK, than also randomly display this again from time to time.  Even with a static IP address assigned this will happen too.

I have swapped the ethernet leads, different port on the switch etc. and the problem persists.  The unit is running 1.14 but I think it did it with 1.13 too.

It's a real pain as I control the PSU via ethernet for some semi-automated testing of items and it's *really* annoying when it happens as it means I have to restart the tests.  The DP832A will complain it is under remote control, but not respond to commands or even a ping when it drops off.  You need to 'release' it using the Back key when this happens before you can talk to it again.  Even when not talking to the unit via IP and just using the front panel the unit will stop responding on the LAN side too.

Anyone else seen anything strange with the ethernet port or is this a developing issue with my DP832A?

I haven't had my DP832 powered on and under observation enough to be at all sure, but seeing a random LXI splash message out of the corner of my eye sounds a bit familiar.

I suppose that is good news in that it looks like a software thing then.

I have been pondering changing it for a.n.other 2 or 3 channel PSU to get 0-60v and a high current, might have a look around and see what will fit the bill.  Defeats the point of scripting tests if you have to keep stopping to reset the PSU to get the comms back.
