I have a question about power supplies.

I am upgrading a 6509 chassis from SuP1/MFSC2 to a pair of SUP720-3BXL's, fan and new power supplies. I originally spec'd a pair of 4000W units. Now as we know, these can only support NEMA L6-30, vs. the variable power supplies such as the 3000W. I've run out of L6-30R's in my data center as our new rack PDU's are of this spec. I may need to use 110V NEMA 5-20 plugs.

Can the 3000W power supply (in redundant mode) support a fully populated 6509 chassis (no POE) when using 110VAC?

Thanks
