[c-nsp] -48vdc lab power

[John van Oppen]

We ended up placing a small-ish Emerson system in our office with a breaker panel and some telcoflex leads to the bench, really works nicely for testing this stuff and was not super expensive but allows bigger loads (ie ASR 9ks to be powered as well).

Thanks both you and the previous poster who pointed me in the right direction. In this case, I'm in actual telco central offices and yes they are straight -48vdc all the way, ac is verboten.
