Hi Geert and all,
It seems to be compatible. Here is a sort of a text in a faq:
Q. Does the Cisco Catalyst 3550-24 PWR switch support the upcoming 802.3af
inline power standard?
A. This switch will support the Cisco inline power implementation and
15.4W/port on all 24 ports. 802.3af compliance cannot be claimed due to the
current status of the proposed standard (draft form) and litigation
involving an alleged patent violation for the power disconnect portion of
this standard. Full 802.3af compliance is dependent on the outcome of this
litigation. Vendors claiming current support for this standard should also
inform their customers of the risk associated with draft standard claims.
The 802.3af standard is expected to be ratified Q3CY03. Backward
compatibility will ensure that previously sold Cisco IP phones and wireless
access points will be compatible with the new Cisco Catalyst 3550 inline
power switch. Development of an 802.3af inline power Cisco Catalyst 3550
switch has been difficult because of the uncertainty that has existed in the
formation of the final IEEE standard.
Regards
Franck
