Okay,

    The Power Distribution Unit should be just that and downstream of the 
UPS, but feedable thru the Maintenance Bypass switch which is
just downstream of the Automatic Transfer switch.  In the event of a UPS 
Failure, or long duration Maintenance project, like swamping all the 
batteries.  In the paranoid world I live in,  this whole feed process will 
be duplicated, with a redundant PDU feed to each Rack, and 6-20AMP outlets 
from each PDU.  Then the servers with redundant pwr supplies are tied to 
the separate Pwr feeds.
