Carl: A couple of more questions and that should be it.....When are you looking to have this service up and running? Also, I am attaching an e-mail from some of our Telecom engineers re: the specific questions we need answers to re: the power issue......And lastly, the collo space that we are planning to provide to you is in a Telecom cage which means that you will not have free access 24 hrs/day (I believe escorted access is available 24 hrs/day but middle of the night access is not pleasant for whoever escorts you)...Will this present a problem?

Listed below are the power requirements as given to me by Pete Ferris for the Internet Fair.
o Power Supplies AC Voltage 1 - 4 AC or DC ; 200 - 240 V ac @ 13 amps Question - Please verify number of circuits required. Is the DC notation an error? Please note: Only 208 VAC circuits are available at the GLW colocation facility.
o AC wall receptacle NEMA L6m-20R (USA) Question - Please confirm this NEMA description. My charts only lists an L6-20R receptacle. I assume one receptacle will be required for each circuit to be verified above.
o -48 V dc power supply input voltage = -40.6 to -58 V dc input current = 63 amps max. inrush current = 80 amps peak max. Question - Does the equipment require both A and B power supplies or A power supply only? Does this equipment use AC power and DC power simultaneously or does it switch from AC to DC in the event of a utility power outage?
I will have my consultants verify if these power requirements can be met with our existing power plant and estimate the cost and time required to upgrade the plant if neeed.
