The M12000P-48GT/4SFP-EA service card's four back ports are fiber/copper combo ports. Each SFP port is
corresponding with a combo 10/100/1000BASE-T port. Only one port can be used at a time. The automatic
MDI/MDI-X identification function of the 10/100/1000M electric port takes effect only when auto-negotiation is
enabled.
