The 7210 SAS-K 2F1C2T, 7210 SAS-K 2F6C4T, and 7210 SAS-K 3SFP+ 8C support combo ports. The combo port provides two physical interface options to the user. One option is to configure it as an SFP port allowing for fiber-based connectivity and speeds of 100/1000 Mb/s with the advantages of using suitable optics for longer reach. The other option is to configure it as a fixed copper port, which provides cheaper connectivity for shorter reach. The SFP port support 100/1000 Mb/s speeds and the copper port can support 10/100/1000Mbps speed. The combo port can be configured either as an SFP port or a copper port. Both interfaces cannot be used simultaneously.
