Description:
The Ethernet Switch 425-48T has 48 10BASE-T/100BASE-TX auto-sensing ports, 2 flexible combo uplink ports, and built-in stacking ports. It can be used standalone or in a stack of up to 8 switches to get up to 384 10/100 Mbps ports, that can be easily managed as a single unit. A scalable, stackable architecture enables up to 8 switches to be connected to support up to 384 ports. Two flexible combo uplink ports for high-speed connectivity to wiring closet or backbone devices. Wire-speed performance is delivered by a 16 Gigabit per second (Gbps) switch fabric that supports full frame forwarding and filtering across all ports at wirespeed performance.
