Access switches choice

Hi All

For a remote site we plan to purchase two POE access switches 48 ports 10/100/1000 with stacking options. 

I am not confused on selecting between 2960S and 3750 ; any suggestion based on experience

thanks

Vishal

Do you want dual power supplies?  If yes, then 3750X.

Will you have a stack of switches > 5 units?  If yes, then 3750X.

Just to build on the main points leolaohoo has already highlighted, the 2960-S series switch will tie you to either 1GbE or 10GbE uplinks. Whereas the 3750-X series switch uses an uplink module, so you can start off using 1GbE fibre and then upgrade the module at a later date in order to facilitate 10GbE fibre or 10GbE copper uplinks. Obviously, 1GbE copper uplinks don't require any uplink module.

The 48-port 2960-S series switch will also tie you to supporting either 24 or 48 simaultaneous 15.4W PoE ports. However, if you don't initially require more than 24 simaultaneous PoE ports, then a 3750-X series switch will enable you to start with the 715W PSU, but add a second PSU later, if required. Alternatively, the 715W PSU can be replaced with a 1100W PSU to simaultaneously support 15.4W PoE across all 48-ports.

Note that Cisco IP phones don't require anything like 15.4W all the time, so in practice the smaller 715W PSU should support more than 24-ports. However, wireless APs are likely to need a bit more than the phones and thin clients will need a lot more than 15.4W (i.e. PoE+).

Stack convergence time is much quicker on the 3750-X series and stack bandwidth is much greater (over 3 times more.)

There are dozens and dozens of other benefits to the 3750-X series. This technical deep dive directly compares the two platforms:

Any other specific requirements?

Thanks a Million to both

Vishal,

I sent you a PM.
