V-lan

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

5.Installation

Packing List
Before installation, please check the following equipment and accessories, if there are any missing, please contact with your supplier.
1) 1 set of DF- 155M-4P-E
2) 1 power adapter
3) 1 user manual
warranty card
 
Please install as below steps
Before installation, please turn off the power of all signal sources and the monitor in case of the damage to transmission device
Using network cables to connect with Ethernet ports of IP cameras and POE ports of PSE-2 series unmanaged POE switch
It using UP-LINK port to connect NVR or computer devices.
Check weather installation is correct and the device undamaged. Before power on PSE-2 series unmanaged POE switch, make sure that all connections are reliable
Confirm all network devices are powered and can work normally.
 

6.Troubleshooting

When the device encountered with troubles, it can be solved by the methods below:
1) Make sure the device is installed correctly referring to the requirements;
2) Make sure RJ45 cable is good contacted without open circuit; the cable design complies with EIA/TIA568A or 568B international standards.
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.

7.Making methods of RJ45 connector

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