Product Overview

The 3Com SuperStack 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.

Gigabit to the desk prepares your network for the future at prices comparable to those of some 10/100 switches. Tri-speed operation at 10-, 100-, and 1000Mbps allows easy migration to Gigabit speeds.

Investment protection is further enhanced with switching silicon designed to support multilayer switching.
