I just had something strange happen and I am not sure why.
I have a c3750 switch stack with 1 Master and 3 Member switches. All 4 switches have RPS power connected.
Member switch 3 at the bottom of the stack showed that the onboard power supply had failed and RPS had taken over. I had a spare 3750 to take its place, and every device in member switch 3 was multihomed with member switch 2. so we pulled the RPS power cable on member switch 3 to replace the switch.
Once we pulled the RPS power cable member switch 1 and member switch 2 boot, and member 3 is down(obviously). the Master stayed up.
Why did member 1 and member 2 boot when I pull power of member 3? This isnt nomral operation is it?
