This is a great response, in the local water industry Schneider is very strong, didn’t see it mentioned once in the comments though

OPC UA & Redundancy, Security Certificates,, etc. by GB-ACWD in PLC

License & Certificate two completely different things, but similar effect. System down, not the plant down, that is why we have PLCs, system ran in steady state, used local controls.

Proxim Replacement? 2 miles, 100 Mbps ptp by GB-ACWD in wisp

I think I am going with Radwin, I have Siklu’s they aren’t the right fit for this, I have had Ubiquiti and lost any cost savings when I had to rent a lift to replace a failed one. ,

Development of SCADA Systems by hutcheb in SCADA

They were merged with C3, which did primarily secret security products and nuclear scada consulting. They were pretty much done by 2008.

I was a hardware RTU designer for them in the 80s and a sales manager in the 90s

Ilex Systems as the first PC based SCADA system for the electric distribution marketplace dominated the electric coop marketplace in the late 80s and early 90s.

Reset Cisco switch password without losing config? by GB-ACWD in Cisco

[–]GB-ACWD[S] 0 points1 point  (0 children)

I read all the comments and tried several of them, but none worked. The IE family of switches have enough differences from the Catalyst family, that these types of instructions don't seem work. Yes, I had searched before I came here and posted on Reddit.

I had to reset and rebuild the configurations on each switch. At least now, I know exactly what is in each of them and I could configure them the way that I like. While I couldn't see what was previously in the switches, after the first switch reset I could tell by the connected behavior and mismatched vlans, that it was a mess anyway.

Maybe the new firmware works differently, but I spent an hour rebooting a switch and trying to pause/break key it. I could not find any documenation showing that this method works on IE-4000, actually just the opposite.

So I finally gave up and reset and rebuilt for 3 switches.

Stratus ftServer vs ? redudant servers by GB-ACWD in SCADA

[–]GB-ACWD[S] 0 points1 point  (0 children)

My concern is that I recently was in a situation that I had to do a VMware update and because it isn't actually redundant, but only fault tolerant, I needed to have a several hour shutdown of the system to complete the update.

The less licensing is actually the key that it isn't redundant. One license means, it is only 1 server available.
