7960 Legacy POE

Unanswered Question
Jul 18th, 2010

Will the Cisco small business 24-port 10/100 POE switch (model 'ESW-520-24P') provide POE to my existing 7960 phones?

My office is moving and I am trying to phase out the Powerdsine POE midspan injector+Catalyst 2960 combo we currently have and replace it with one of these.

Our current 7960 phones are each equipped with a POE crossover dongle (I think these are used to provide legacy inline power to the phones from the 802.3af injector source)  

Just trying to make sure I order correctly.

Thank you!

I have this problem too.

Hi Adam,

Q.
Do the Cisco ESW 500 Series PoE switches support Cisco pre-standard Power over Ethernet?

A.
No. For Cisco pre-standard PoE, we recommend the Cisco Catalyst 2960 Series Switches, which support both 802.3af and Cisco pre-standard PoE.
