The HP ProCurve Switch 100/1000Base-T Module is a single-port 100/1000Base-T Ethernet module for the HP ProCurve switches 8000M, 4000M, 2424M, and 1600M.

The HP ProCurve Switch 100/1000Base-T Module allows Gigabit Ethernet connections over Category 5 UTP wire or better.
This module is an ideal low-cost, high-bandwidth solution for switch-to-switch or switch-to-server connections and -- at a price two-thirds the cost of the HP ProCurve 9300 Routing Switch Gigabit-SX solution -- the module's connections are expected to replace the use of Gigabit-SX connections for distances under 100m
