4506 Power requirements

I need information on the new 4506 switch as it relates to power comsumption. I have 2 questions.

I need a power source to connect a wireless AP1200, both radios without using a Power Injector. Can the new 4506 be used to power a quantity of 17 AP1200 (both radios 7.5 watts) by just using an inlne power blade?

Can this same 4506 supply power to Cisco IP phones if the 4506 is fully loaded with 6 48 port inline blades?

Re: 4506 Power requirements

Yes, the new 4506 is compatible with the inline power of the AP1200 series.

The 4506 with the 2800w power supplies can fully power 5 blades of 48-port inline power. Only 5 because one of your slots belongs to the Supervisor of your choosing.

Look at the following links for more info:

Re: 4506 Power requirements

I want more detailed answers please.

Can the AP1200, radio a and radio b both get power from the 4506 with a 2800 watt power supply from a WS-X4148-RJ45V blade? I understand that any port on this blade only supplies 6.3 watts. Is this correct? If this is correct, then it is impossible to get 11watts out of a WS-X4148-RJ45V port. The radio A and B need 11watts when both are active.

Please give me a solution for this configuration;

one 4506 with 1 Supervisor II, four WS-X4148-RJ45V blades, 68 IP phones and 17 Access Points 1200 with both radio A and B active.

Re: 4506 Power requirements

According to the link below, you cannot do inline power with the 802.11a radio.

It is at the bottom under the section Table 26-8: Product System Requirements

Re: 4506 Power requirements

I think the issue you're running into is the need for the 802.11af standard support with 15+W of power on each port - that is not available in the current 48-port blades but will be on a future blade of course - there haven't been any part numbers or availability dates announced yet though...

You should still only need this if you are looking at 802.11a support - 802.11b works fine on the existing power blades - but dual support for 802.11a and b will indeed put you into 802.11af territory (or the stand-alone injectors).

If it's for planning purposes to try to plan a future purchase, talk to your AM or SE - they should be able to give you a heads up when the product is announced.
