 Combo ports - It is a single-logical port that has two (2) physical connections, the RJ45 connector (copper) and SFP connector (fiber).
  • Only ONE of the two (2) physical connections may be used at a time.  The system will automatically detect the media that is in use on a combo port. 
  • If both RJ45 and SFP are present (link up in both connections), the SFP will be active, and the RJ45 connection will be disabled and ignored.  The RJ45 connection will be in standby and automatically enabled if the SFP link goes down.
  • The SFP and RJ-45 interfaces share a common link/activity and speed LEDs.
  • Some port controls are affected by the actual physical connection used.
  • The SFP interface supports both Gigabit and 100 Mbps speeds.
  • SFPs officially tested:
–      PTO-S1-4103K- IE
–      PTO-M3-4D33K- IE   
–      PT4-S1-4103K- I
–      PT4-M3-4D53K- I
