4 ports only for PoE? I think buying a 24-port PoE is a very expensive choice. May I recommend you buy a 4-port mid-span PoE switch instead?

If you Google "mid-span" poe, you'll find a number of manufacturers.

Another thing I would like to know is what are you trying to connect? Mid-Span PoE ports comes in a variety of "flavours", some will give you STANDARD 15.4W (or less) power but there are some which can give you 20.0W or 30.0W of power per port.

Now, if you are still determined to get a PoE switch, I would like to determine from you, for a 48-port PoE switch, if you want ALL 48-ports capable of delivering PoE? If you say yes, then the only choice you've got is the WS-C3560-48PD-SF or WS-C3750E-48PD-SF.

WS-C2975 (48 10/100/1000 PoE up to 24), WS-C2960G, WS-C3560G, WS-C3750 (24 OR 48 10/100/1000 PoE up to 24) are likely candidates.

Hope this helps.

Hi !! Thanks for the update... I am aware of 3560G with Dedicated POE for 24 or 48 Ports. But my solution sghould be with 24 or 48 10/100/1000 NON POE Ports & only 4 POrts POE. This is the challange

So you want to know if there is a Cisco switch that can provide only 4 PoE ports?

Here are your options:

1. Get a 4-port mid-span PoE switch and get a 24 or 48 port 3560G (non-PoE); or

2. Get a 24-port 3560G PoE and for the 20 interface, use the "power inline never" command.

Hope this helps.

CE500-24LC

This cisco switch has 20 non-poe ports and 4 poe ports but is 10/100, not 10/100/1000.

2960-24LT-L

2960-24LC-S (Lan lite software)

These cisco switches have 24 ports including 8 poe ports but are also 10/100, not 10/100/1000.

Might seem a little simplistic but have you thought about just getting 4 power injectors (we use these for phones connected to 3500 Catalyst)
