HA XG-2758 - SFP Question



  • Hello,

    I am looking at the XG-2758 HA Model https://store.pfsense.org/XG-2758-HA.aspx and trying to understand exactly how many SFP ports it comes with PER SYSTEM (note: SFP not SFP+).

    Any idea?

    Attached is a closer look at the front panel and I see one port marked as SFP, but it also connects to one of the other ports marked as IGB1. Does it mean the IGB1 can also be used as SFP?

    I will need to use the SFP ports for 1G uplink to Cisco L3 switches and like to know exactly how many SFP connections I can utilize PER SYSTEM in the HA environment.

    Thanks.

    igb1 can be either copper or SFP. Plus the two SFP+ ports, so three.

    2x 10GbE SFP+
    3x Intel 1GbE
    1x Intel 1GbE RJ-45/SFP

    2x 10Gb Ethernet SFP+ via Intel 82599 Niantic
    4x 1 Gb Ethernet RJ45 via Intel i354 on-chip; one port configurable as RJ45 or SFP

    Thanks. But, wouldn't that make it four in total? Because, there is also another port marked as SFP? So, I have 1xSFP,1x igb1 (that can be used as SFP) and then 2xSFP+?

    If I want to make use of 1xigb1 as SFP then do I buy the same transceiver as the one that I would install it on the existing SFP port? I am trying to understand how that igb1 port can be used for RJ45 (copper) or SFP? Aren't those two connector types?

    It's what's called a "shared port." igb1 can have either the SFP or the RJ45 active. Pretty common. Lots of switches work the same way, for instance.

    There are 6 ports.

    Two SFP+ (ix0, ix1)
    Three Gigabit Copper (igb0, igb2, igb3)
    One shared SFP or Copper (igb1)

    2 + 3 + 1 = 6

    Not sure what to tell you about which modules to get. Probably the ones you can add to the order would be a good place to start.
