I would suggest the Cisco 300 series managed switches, either the SF302-08MP or SG300-08MP. Both provide 8 PoE ports with an additional 2 combo mini GBIC ports (2 x Gigabit copper or SFP).
The difference is the SF model PoE ports are fast ethernet while the SG's are gigabit.
Note that there is a non M version which is cheaper but only provides half the PoE power. The M version is able to provide the full 15.4W to all 8 ports.

If the APs are gigabit then, yes, you'll need a gigabit port switch.
The SF is fast ethernet and SG gigabit, so if you go for 300 series, you will want the SG model.

PoE is delivered over shielded or unshielded ethernet cable, so the maximum distance for an AP from the switch will be 100m. For 300m to 400m runs to the switch you will need to use fibre.

The SD208P 8-port 10/100 Switch is an unmanaged, RJ45 fast ethernet only, PoE power limited to 34W total on ports 1 to 4 only. This doesn't meet your requirements.


It's not clear in the original question whether you also need wireless LAN controller functionality as well.

You're installing an enterprise-class wireless network.  The 3602 are Cisco's top-line.
Use something like a 2960S-24LPD-L

Have a look at this...

http://www.cisco.com/en/US/products/ps6406/prod_models_comparison.html

If you want to go with the cheaper Cisco switches you should consider the 300 series, specifically the SRW2008MP-K9-NA.

Be careful if you go with a small switch though.  The SRW2008P-K9-NA is PoE capable but only on 4 ports, yet the SRW2008MP-K9-NA is capable of PoE on all 8 gigabit ports.

You will also need a controller with the 3602 APs.  Depending on the amount of APs you want you can typically use a 2504 or a 5508.  The 2504 is great for up-to 50 APs, yet the 5508 will allow you to connect up-to 500 APs to a single controller.

correct craig , above meodel makes sense to me .  2960S-24LPD-L

and i am using 5508 WLC with 250 License which is costing me around 32,000 $ , quite expensive .

I was wondering that if we have any switch with 8 poe ports and no non POE switch  ??? as above model has all POE ports in it . and also this cost me around 3000 $ . Also my requirment does not very exceed more than 8 at any point where i need switch .
