What is the power draw of the SPA500?

May I re-ask the question; What's the power draw of the SPA500 series phones (each one) as there is nothing in the datasheets.

Thanks

It varies a bit depending on what it is doing, but on PoE a 504 generally stays below 5W. Mains could be more/less depending on voltage conversion etc.

S

So both switches (ESW -24-48) should support all ports..?

What about the 525?

Bob,

     Please review the attached document for PoE specifics per phone.

Best Regards,

Thanks Glenn!

I don't know why these are not posted on Cisco.com...

I assume these measurements are in Watts?

That is very helpful

Bob,

     Yes Watts.

Hi Glenn the table you posted it's very help full, that info should be included in the product datasheet.

So I want to confirm, that provided  I have an ESW-520-24P switch with 180 Watts power budget, this switch is supposed to support 24 SPA502 IP Phones at full load?

Thanks.

Per the chart the maximum power draw for the SPA502 is 1.620 watts.  The 180 watt power budget of the ESW-520-24P should be more than sufficient for that number of phones.

Best Regards,
