As it turns out the PDU plugs are the same - the different plug styles are due to amperage, not voltage. Room power was done two IT guys ago and the fact that the PDUs were attached to 230 was forgotten when it was passed from him to my predecessor and then from the predecessor to myself. Found out real quick though. I have very bright yellow signs up now warning which plugs are 230 and which ones are 115.
The University physical plant does track room voltages and which circuits get which power, but unfortunately they're not so good at actually communicating that out to those of us who actually have to work with their creations. ---- Jack Kramer Computer Systems Specialist University Relations, Michigan State University w: 517-884-1231 / c: 248-635-4955 On 3/25/11 5:54 PM, "Brian Desmond" <[email protected]> wrote: >Usually it's a different style plug, no?
