[c-nsp] Cat 6509 Power supplies

[Childs, Aaron]

Hi Bill,

It all depends on what other modules you have installed in your chassis.  I am running a 6509-E with 3000W power supplies using 110v, however I have to run them in combined mode.  To give you some real-time data here's the output from my 'sh power':

system power redundancy mode = combined
system power total =     1952.16 Watts (46.48 Amps @ 42V)
system power used =      1275.54 Watts (30.37 Amps @ 42V)
system power available =  676.62 Watts (16.11 Amps @ 42V)

Subject: [c-nsp] Cat 6509 Power supplies

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
