To enable fiber or additional copper connections on your switch, SFP and SFP+ ports accommodate standard small form-factor pluggable (SFP) gigabit interface converters (GBICs) for 1G fiber or copper connectivity and, for models GS728TXPv3 and GS752TXPv3, 10G fiber or copper connectivity. GBICs, also referred to as transceiver modules, are sold separately from the switch.
On model GS728TXPv3, only ports 25 and 27 support 10G copper modules; On model GS752TXPv3, only ports 49 and 51 support 10G copper modules. If you insert a 10G copper module in an upper SFP+ port, do not insert any module in the SFP+ port just below it. If you insert 10G copper modules in the two upper SFP+ ports, do not insert any modules in the two lower SFP+ ports.
Any third party GBIC incorrectly detected by the switch as either fiber or copper module might result in different behaviour; for example, fiber GBIC recognized as a copper module does not work on ports 26, 28, 50, or 52. We recommend using NETGEAR GBICs only for ports 26, 28, 50, and 52, and to follow the instructions in the Hardware Installation Guide, which you can download by visiting netgear.com/support.
