Do we need a POE switch in order to support wake on lan on our server and PCs?
Our company has PCs (as well as a server) that have the Wake on LAN ability and I know there will be some configuration required on the PC side as well as the router (for port forwarding). I did notice that Cisco sells POE enabled switches and I wanted to know: Do we need a POE enabled switch for wake on lan to work properly?

POE stands for Power Over Ethernet. POE switches are useful for powering small devices over ethernet wiring. An example might be ethernet-based cameras. There are many applications, but essentially the technology allows you to power devices over an ethernet cable instead of a wall outlet.

So, if I'm correct, that means we could just use a POE enabled switch to power POE devices rather than buying separate POE adapters for each device?
That is correct. Those adapters are sometimes referred to as "PoE Injectors." If you buy more than a few, they don't save you any money.
Correct.
One thing to consider is the number of data ports you need versus the number of PoE devices you have. For example, if you need a 48 port switch, but only have 3 PoE devices such as a few AP's, it is likely to be more cost-effective to purchase a few inline power injectors (not power bricks with the round connectors that plug directly in to the phone) and locate them in the switch closet. You'll get all the benefits except remote power up/down. Now in the same 48 port scenario, but with 20 PoE devices, definitely go with the PoE switch.

Thanks for the quick response
...I always find it amusing when two of us write a response simultaneously with pretty much the exact same answers.
No problem.
