    24-port  10/100M POE Switch


    Product Description

    The POE Powered Switch supports the IEEE802.3af/at power over Ethernet standard with a power distance of 100 meters and only powers 802.3af/at terminal devices, so there is no need to worry about compromising proprietary standards for POE or non-POE devices. In addition, the POE device stops supplying power when it is not connected. These devices, which are far from the power outlet, are suitable for hanging on the wall or on the ceiling, and the POE eliminates the need to connect the power outlets for these devices, making the connection to equipment that is difficult to connect to AC power more flexible and with minimal installation costs. This series POE Powered switches are ideal selection for small business networks that want to use the economic deployment of wireless access points (AP) and IP-based network surveillance cameras .

    Installation Step:

    Please check below device and accessories before installation, if there are missing, please contact with your supplier.

    1.    POE Switch                                         1 PCS

    2.    Power Adapter/Power Adapter Cable      1 PCS

    3.    User Manual                                         1 PCS


    Please follow the following steps

    ◆  Please turn off the signal source and the device's power before installing, installation with power on may damage the device;

    ◆  Use the network cables to connect the IP cameras with Ethernet switch's every POE port;

    ◆  Use network cable to connect Ethernet switch’s UPLINK port with NVR or Other Device;

    ◆  Connect Ethernet switch with power adapter;

    ◆  Check if the installation is correct and device is good, make sure all the connection is reliable and power for the system;

    ◆  Make sure every network device has power supply and work normally.

    Problem Examination:

    Please remove the problem according to the following steps

    ◆ Please confirm if the device installation is correct;

    ◆ Please confirm if the RJ45 reach the standard of EIA/TIA568A OR 568B;

    ◆ The maximum transmission distance depends on the signal source and cable quality, please do not over the maximum transmission distance;

    ◆ Please replace a normal device with a failure one to check if the device is broken;

    ◆ If the problem still exist , please contact the factory.
