    We are creating a new POP and I have the option of getting EX4300-24T'sor EX3400-24T's. From the looks of it seems that the 4300 would be the clear choice. It seems that the 3400 is a bit newer and I just wanted to see if it had anything better such as a better CPU etc. I wont be using anything fancy on them. I just need basic layer 2 functionality such as vlans etc. and I must have dual PSU's.

    The Juniper product compare tool lets you see the specs of two devices side by side.




    The ex4300 is essentially double the capacity of the ex3400 and more high speed optic options.


    The detailed specs both list dual core processors and the same ram but without mentioning which cpu is in the ex3400.  I don't see anything that would suggest the ex3400 would be a better choice between the two in hardware or specs.
