[Soekris] net4526 & a speaker

[Manuel Requena]

And you know what switching device will provide the PoE connection? And the maximum power it will
provide?

As I know, Cisco switches have modules that provides 7W and 15W.

"Clause 33 of IEEE 802.3-2005 (commonly referred to as IEEE 802.3af) provides 48 volts DC over two
of the four available pairs on a Cat. 3/Cat. 5 cable with a maximum current of 400 mA for a maximum
load power of 15.4 W."
