With twenty-four 10/100 Mbps RJ-45 ports, two Gb E copper ports & two shared SFP / copper Gb E interface, Zy XEL ES-3124 boasts a high performance switch architecture that is capable of providing non-blocking switch fabric & wire-speed throughput as high as 12.8 Gbps. Its four built-in Gb E uplink ports also offer incredible extensibility, flexibility & connectivity to the Core switch or Servers. Featuring " Backup Power System Support" design for even higher availability, Zy XEL ES-3124 adds a built-in DC power receptacle on its rear panel for external Backup Power System connection; & the system can switch to the alternative power source automatically in response to different situations. Zy XEL ES-3124 is loaded with powerful traffic management & Qo S features to enhance services offered by telcos. For instance, the ES-3124 provides 8 priority queues per port for different types of traffics, allowing administrators to set policies for classified filtering & rule-based rate limitation. The ES-3124 prioritizes applications with WFQ (Weighted Fair Queuing) scheduling algorithm to allocate more bandwidth to key traffics such as voice transmission, empowering the enterprise to take full advantages of the limited network resources & guarantee the best performance. In addition, the ES-3124 also supports a variety of ways to categorize & prioritize network packets; multilayer information from L2 to L4 can be used to classify packet priorities for alignment with ACL features to construct a platform for Multi-Service Networks. Zy XEL ES-3124 offers comprehensive Access Control List (ACL) for enforcing security to the edge. Its protection mechanisms comprised of per-port MAC filtering, limited per-port MAC number, port-based 802.1x user & device authentication, as well as TCP/UDP Socket filtering to control the network services accessible to employees. Thanks to these solid mechanisms, the administrators can now construct highly secured corporate networks with time & effort considerably less then before. Users may stack works by assigning two VLAN IDs to each frame header. One is a "backbone" VLAN ID used by the service provider, & the other provides up to 4, 096 unique 802.1Q VLAN tags. The ES-3124 support VLAN Stacking, namely Q in Q or Tag in Tag that help Telcos or Carriers to easily establish IP VPN networking architectures. With supports to advanced features like i Stacking, SNMP, Web, telnet, RS-232 & RJ-45 MGMT ports, the ES-3124 is very easy to deploy & manage. Better yet, its underlying Zy XEL i Stacking technology allows up to 24 clustered switches to be managed by just one IP management, enabling users to benefit from significantly reduced operation & maintenance cost. Please note: networking components such as switches, routers, UPS & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
