Note:If any changes with product specification, forgive without prior notice.
1) As transmission distance has certain relation with the cable, so you are suggested to use standard cat5e/6 cable for longest distance needed.

In addition, sincerely hope the following info will be helpful for you to understand our POE switch. 
1.The chips we always use for POE switch are Broadcom and Marvell;
2.In the backside of our POE switch, there is a switch(named default and CCTV switch) can adjust the transmitter distance between POE IP camera and POE switch, pls kindly note the max transmitter distance we can reach is 250m. 

10/100m Single Mode Single Fiber 8 Poe Switch Sc20km
3.All our POE switchws are intelligent, therefore it can supply enough worked power for all equipments that POE switch connects with according to the equipments' need.  So the customers do not need to worry the equipments will burnout when POE switches supply big power much more than what they need, or the equipments can not work well if POE switches do not supply enough power to them;
4.All our POE switchws are compatible with IEEE802.3 af/at standards;


4.1 Introduction

    When V-lan function is opened, the LAN port can't make data conversion but can only communicate via uplink port. The V-LAN workstation is built separately between every network port and UP-LINK port.
In the same V-lan workstation, no matter which actual PoE switch being connected, the signal transmission are separately isolated from each other which seems they are on the different switches. The broadcast in the same V-lan can only be received by the members but can't be transmitted into other V-lan, which can greatly control unnecessary broadcast storm. What's more, different V-lan can't even communicate with each other when there is no routing, which increases the safe degree among different department in the enterprise.

4.2 Configuration

   Toggle the V-lan button on the back of the switch to ON state, V-lan indicator lights, then press the reset button to restart the switch, in this way V-lan functions.

   Please press reset button or repower the device when turn on V-lan, only in this way the switch can enter corresponding mode.

3) Each PoE port can provides max 30W to switch and the total power is less than the maximum power provided by the device. So please don't connect with the PoE device which is more than 30W;
4) Press reset button to check if the device can work properly;
5) Replace the trouble device with a normal working device to check if the device is damaged;
6) If all the above methods still don't work, please contact with manufacturer directly;

8.Making methods of RJ45 connector

1.Required tools: wire crimpers, network cable tester;
2.The wire sequence of RJ45l connector must complies with international standard of EIA/TIA 568A or EIA/TIA 568B;
3.Strip about 2cm's of insulating jacket to let 4 pairs UTP can be seen;
4.Separate 4 pairs UTP cable, and try to straighten each pair;
5.Arrange 8 cables with correct line sequence of EIA/TIA 568A or EIA/TIA 568B;
6.Cut thread residue and leave 1.5cm wire which exposed outside the insulating layer, and ensure 8 wires are straight and neat;
7.Put 8 wires in RJ 45 connector, then press with wire crimpers;
8.Repeat above five steps , make the other side of UTP cable; Then using the cable tester to test whether the cat5e/6 works normally;
