An engineer (it's really hard to get a true engineer on the horn versus a service rep who knows next to nothing) and he ask us to discontinue that approach. I suspect that the reason is because microprocessors get confused when B+ is applied before ground which is why when you hard reset you always apply the ground first. Admittedly we did not have a problem, at least not that I am aware of. So I cannot say conclusively, not to do it. I'm just passing on what was shared with me. Since that time we have converted over to the 5511e switch when using ACR/VSRs.
