Huawei POE Switch S3700 28TP PWR SI

    Huawei POE Switch S3700 28TP PWR SI

    S3700 28TP PWR SI is a Layer 3 switch in Huawei 3700 series switches. Built-in 2 Gigabit Ethernet ports and hot-swappable power supplies provide an effective solution for network management.



    The Smart Ethernet Protection (SEP) function protects the security of the network in real time.

    24 Ethernet 10/100 PoE ports can connect multiple external devices simultaneously.

    Hot-swap capability ensures the longevity of the switch.
