  • Advanced System Structure
    The H3C S7500 Series introduces the distributed system architecture and powerful ASIC chips for high-speed routing, as well the Crossbar technologies for packet switching. This creative combination greatly improves the forwarding performance and expansion capabilities of the routing switch. Embedded in the Main Control Units (MCU), the Crossbar switching fabric provides a switching capacity up to 768Gbps and works in the active/standby or load-sharing mode set by simple software configuration.
  • High Capacity, High Density, Wire-Speed Forwarding
    High Capacity----The H3C S7500 Series can provide 1.68Tbps backplane bandwidth and up to 768Gbps switching capacity and 432Mpps forwarding capabilities with Salience™ III Plus engine.
    High Density----The H3C S7500 Series can support ultimate 288 GE or 288 FE or 24 10-Gigabit wire-speed Ethernet interfaces totally.
    Wire-Speed Forwarding----All the high density Gigabit (48-port) and 10-Gigabit (4-port) interface modules with XGBUS uplink can reach to L2/L3 wire-speed distributed forwarding in full loaded of S7503 or S7506R with new Salience™ III Plus engine.
    Simply put, the H3C S7500 Series provides flexible interface choices from 10/100/1000 to 10 Gigabit Ethernet and combined interface boards to satisfy the customer
