What Is the Rate of an FC Interface of a CE Series Switch?

What Is the Rate of an FC Interface of a CE Series Switch?

Only the CE8860EI, CE8861EI, and CE6850U-HI support FC interfaces.

  • For the CE8860EI and CE8861EI:

    • When the 16G FC optical module is used, the rate can be 4000 Mbit/s, 8000 Mbit/s, or 16000 Mbit/s.

      The maximum rate supported by a 16GE FC optical port is 14 Gbit/s.

    • When the 8G FC optical module is used, the rate can be 4000 Mbit/s or 8000 Mbit/s.

    • When the 4G FC optical module is used, the rate can be 4000 Mbit/s.

  • For the CE6850U-HI:

    • When the 8G FC optical module is used, the rate can be 2000 Mbit/s, 4000 Mbit/s, or 8000 Mbit/s.

    • When the 4G FC optical module is used, the rate can be 2000 Mbit/s or 4000 Mbit/s.

    • When the 2G FC optical module is used, the rate can be 2000 Mbit/s.

In non-auto-negotiation mode, if interfaces on two connected devices work at different rates, use the speed command to change the rates of the interfaces to be the same so that the two devices can communicate.
