I'm pretty inexperienced when it comes to setting up power for a network rack. I have a location that has a dedicated 20 amp circuit with a LP-20P socket. I have a APC UPS 3000XL rackmount UPS and a TripLite PDUMH20 PDU.
I'm looking at the current configuration where things are configured like this: [Power Source] --> [PDU] --> [UPS] --> [Network Gear].
I can't help but feel this is incorrect. Won't the UPS "obscure" the draw of all the downstream devices?
What is the correct power path for UPSs and PDUs? Does the UPS go to the PDU or the other way around? Does it make a difference?
