Product Description

BD-S2228PoE is a modularized hi-performance workgroup-level or enterprise-scale switch,

with 24 Fast Ethernet ports，plus maximum 4 gigabit ports. BD-S2228PoE can connect all (Fast) Ethernet devices so that your investment is protected.The hi-speed connection it provides among workgroups can boost the capability of server clusters, and solves the bottleneck caused by increasing users and limited bandwidth, making network resources more readily available to you.

Application

· Hi-performance, network manageable inter-workgroup or enterprise-edge switching

Features

Performance

· 36 Gbps switch fabric, hardware routing, wire-speed L2 forwarding rate: 9.5 Mpps
