Good morning spiceheads,
I'm working on a new project and could use your help. We are looking at adding/replacing UPS for all our network IDF/MDF's at the school district.
I have several closets using HP 54XXzl chassis switches with 4 220V PSU's, (1500W each or 6000W total) Each of these closets have a small 100amp breaker box in them, with 4 quad plugs for the chassis switches to utilize.
In that environment would it be better to directly wire the UPS to the breaker or plug it into the existing 220V outlets.
For the racks/switches would it be better to get a PDU that the rack/switches all plug into and that one unit plugs into the UPS, or plug everything directly into the UPS. Most closets will have 1 Chassis and maybe 2-4 other 120V switches or equipment that needs powered.
Our goal is to have 30 minutes of power for each closet/switch...
