Number of 7945's on a 3560 POE

Specifically I'm looking for the number of 7945's that can be powered with a 3560-PS-S (24 or 48)

Is ther a document or tool that calculates this easily?

30.

7945 requires 12W.

From 3560 Q&A -

Q. How many devices can the Cisco Catalyst 3560 Series power?

A. The Cisco Catalyst 3560 Series 24-port PoE configurations can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. Using Cisco Catalyst Intelligent Power Management, the 48-port version can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. The Cisco Catalyst 3560 Compact Switch can support 8 simultaneous full-powered PoE ports at 15.4W.

Use the PoE Calculator tool for any such calculations in future -

Hope this helps.
