Cisco 2960 PoE

This should be a pretty easy question to answer.  I currently have a Cisco 2960 switch.  I am trying to run wireless in my office and the model I chose was Linksys WAP4400n which supports PoE.  My question is, what makes this thing turn on when plugged into the switch.  Do I have to tell it to use PoE?

It should work with PoE right out of the box. Is it not powering up for you?

No.  I have had my switch running for about a year now, and it has nothing special configured to it.  I just did a reset on my access point to default settings and when I plug it in, its not powering up.  Are there specific ports that use the PoE on the switch or do all 48 ports support the PoE?
 
Thanks for the reply

The default should be "enabled"
To be sure, select the inteface and try the following:
power inline auto

example:
Switch(config-if)# interface gigabitethernet0/1
Switch(config-if)# power inline auto

OK, so is it only available through the two Gigabit ports on this switch or do all ports support it?

I don't have the exact same switch (mine are 3560's), so I can't be positive without the exact model number. I would expect that all ports are capable though. As with most IOS commands, it'll only let you do the command if the port is capable.

You can also try the following to see the staus of the port:
show power inline

OK, Im not real familiar with the command line.  I was working with the GUI interface.  Let me see what I can mess up ;))

Just backup your config 1st!

OK, I downloaded an application from Cisco called "Cisco Network Assistant" and it is more versatile than the interface on the switch.  I have included a screenshot and maybe we can look here before I attempt the command line.  When I view the port settings, it tells me it is Down, but it also changed the status from "Dynamic Access" to "802.1Q Trunk - Nonnegotiate"  Any thoughts on this?

Trunking shouldn't effect the PoE. I'm almost exclusively command line, but I'll have a look at the Network Assistant. It claims to support PoE settings.

OK, well I reset my device to factory settings.  Like I said, there was nothing configured on this so nothing really changed.  When I plug the Access Point into the switch, without the power cord to the AP it shuts down the port.  Once I plug the power cord into the AP device the port turns up.  Do I need a specific CAT cable?  Im running CAT5e to all my devices.  This is really frustrating.
 
Thanks again

Do you have the exact model number of your switch?

It's all clear now... That model isn't PoE. It would have a "P" in the model numebr. WS-C2960P...

If using the power adapter od a problem, you could try an inline power injector. Something like this:
