Appendix A
Cisco Catalyst Specific PoE Information
This appendix discusses Cisco specific information required in order to connect Jack-PCs to
Cisco Catalyst PoE enabled switches.
When trying to troubleshoot PoE problem with Cisco Catalyst switch, first check that the
switch supports IEEE 802.3af PoE. Some Cisco switches are not capable of supporting this
new standard.

Table A1 – Cisco Catalyst PoE compatibility table
Even if the Cisco Catalyst product can support 802.3af it may have older inline power
modules that can only support pre-standard PoE. You need to check the specific inline power
modules installed to verify compliance to IEEE 802.3af standard (see table A2 for example).

If your switch has a module capable of providing PoE to end stations, you can set each
interface on the module to automatically detect and apply PoE if the end station requires
power.
Another advantage / complexity of Cisco Catalyst PoE – intelligent power management to
avoid overload in large switch rack. This means that although there may be 240 x 15.4W
