IP phones power supply

Have found those power supplies for 6500 series.

950W AC input (Cisco Catalyst 6503 chassis)

1400W AC input (Cisco Catalyst 6503 chassis)

1000W AC input

1300W AC and DC input

2500W AC and DC input

3000W AC input

4000W AC input

I used the Cisco Power calculator on the web and try to find out which power supply we should use. We have 170 IEEE Class 3 phones, Cat6509, and we can only use AC100V power input. The power calculator shows the number of ip phones are exceeding the Cat6509 2500W AC power requirement even running in combined mode. In this case, do we need to buy another switch or what is the amps of 3000W AC? We can't use 4000W AC power as this is only for AC240V.

Please advise,

Re: IP phones power supply

The 2500W ac power supply running at 100v is the same as a 1300w ps. Seems like getting the right power (220VAC) would be cheaper that another chassis.
