Hallo-Performance Gigabit Ethernet Switch

BDCOMS2228PoE ----------Hi-performance Gigabit Ethernet Switch Proudly presented by Shanghai Baud Data Communication Co., Ltd. (BDCOM), BDCOM S2228/S2228F/S2228PoE is a modularized hi-performance workgroup-level or enterprise-scale switch, with 24 Fast Ethernet ports(24 100M SFP slots for S2228F),plus maximum 4 gigabit ports. BDCOM 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. More importantly, all of the advantages are brought to you by BDCOM at low costs and with easy maintenance.
