Technical Specifications

BlackDiamond 6808 and 6816 Switches

The BlackDiamond 6808 and 6816 chassis are uniquely designed with carrier-class fault tolerance for IP data networks that require the highest level of availability as well as scalability from 10/100BASE-T to 1 Gigabit and Ten Gigabit Ethernet. Both switches provide wire-speed Layer 2 and Layer 3 switching for consistent performance regardless of traffic patterns or network load.

BlackDiamond 6808

  • The BlackDiamond 6808 supports up to 64 Gigabit Ethernet ports when populated with the 8-port G8Xi or G8Ti modules, and 96 Gigabit Ethernet ports when populated with the G12SXi module.
  • The BlackDiamond 6808 supports a maximum of 768 10/100 Mbps ports when fully populated with the F96Ti, or 224 100BASE-FX ports with fully populated with the F32F module.
BlackDiamond 6816
  • The BlackDiamond 6816 leads the industry in density with up to 192 Gigabit Ethernet ports in a single chassis.
  • The BlackDiamond 6816 supports a maximum of 1,152 10/100BASE-TX ports when fully populated with the F96Ti. In addition, when fully
    populated with the F48Ti,the BlackDiamond chassis will accommodate a maximum of 576 10/100BASE-TX ports, or 448 100BASE-FX ports when fully populated with the F32F module.
  • The BlackDiamond 6816 supports a maximum of 128 Gigabit Ethernet ports when fully populated with the G8Xi and G8Ti modules, or 192 Gigabit Ethernet ports when fully populated with the G12SXi modules.
