3 Switch
3848 delivers wirespeed Gigabit
Ethernet switching, with ten times
the performance of 10/100 desktop
switching but at similar prices. Tri-
speed operation of the switch enables
backward compatibility with existing
devices, such as printers, while still
allowing new PC’s and servers to
operate at their maximum potential.
