All PCI network adapter features use optical connectors.

Switch requirements for the 25 GbE features:
  • You need 25-Gigabit Ethernet capable switches. A fallback to 10-Gigabit Ethernet is not supported.
  • For connections to a Cisco switch, you must set the switch to use FEC RS-IEEE for forward-error-correction (FEC) in Reed-Solomon mode.
