I've got a RPS 2300 with (2) C3K-PWR-1150WAC power supplies installed. 'show env rps' states that there is 300W/850W for system/PoE. I'm not using and never will use PoE on the 3750E switches that I will plut into the RPS.
I know that the RPS will power 2 3750E's no problem. Can I use the same RPS to power a 3rd, 4th 3750E (no PoE)? I'm mainly interested in protecting us from a UPS or electrical circuit issue rather than multiple 3750E internal power supplies going bad.
So my proposed setup would be something like:
RPS-powersupply-1 <> Circuit-B
RPS-powersupply-2 <> Circuit-C
Internal power RPS power
Circuit-A <> 3750E-1 <> RPS-port-1
Circuit-A <> 3750E-2 <> RPS-port-2
Circuit-A <> 3750E-3 <> RPS-port-3
Circuit-A <> 3750E-4 <> RPS-port-4
The switch config guide says that the RPS will provide power to ports based on their priorities and that if it still has power available that it will continue providing power to additional RPS ports. I'm wondering since I'm only using "system" power how much power can I use. System power seems to be where I need to be worried.
