Power the unit and connect to network Cable

1. Wiring Power Inputs 

JetNet 7850G-2XG and JetNet 6852G AC Power Input
Connect the attached power cord to the AC power input connector, the available AC power 
input is range from 100 ~ 240 VAC at 50 ~ 60 Hz.
JetNet 7850G-2XG-DC48 and JetNet 6852G-DC48 DC Power Input
The suggested power input is -48VDC, the available range is from -36 ~ -72VDC.
Follow below steps to wire JetNet 7850G-2XG-DC48 and JetNet 6852G-DC48 DC power 
inputs.

2. Wiring Earth Ground 

To ensure the system will not be damaged by noise or any electrical shock, we suggest you to 
make exact connection with JetNet 7850G-2XG-DC48 and JetNet 6852G-DC48 with Earth 
Ground.

1. Insert positive and negative wires into + and - contacts respectively of the connector.
2. Tighten the wire-clamp screws to prevent DC wires from being loosened.

On the back panel of JetNet 7850G-2XG-DC48 and JetNet 6852G-DC48, there is one earth 
ground screw. Loosen the earth ground screw by screw drive; then tighten the screw after earth 
ground wire is connected.

Device Management

The system may be managed out-of-band through the console port on the rear panel or 
in-band using Telnet, a Web Browser, or SNMP.

1. Web-based Management Interface

After you have successfully installed the Switch, you can configure the Switch, monitor the 
LED panel, and display statistics graphically using a Web browser, such as Netscape Navigator 
(version 6.2 and higher) or Microsoft® Internet Explorer (version 5.0).
The default IP address before configuring is 192.168.10.1. User Name is admin, default 
password is admin.
After configured the layer 3 virtual interfaces, you can assign primary IP and second IP 
addresses to the interface, this is known as default gateway of the lower hosts. The lower hosts 
in each subnet can access the interface by the default gateway IP address.
The default IP address is only available in layer 2 mode, the layer 2 mode means there is no 
any configured layer 3 virtual interface. After configured the layer 3 virtual interface, the 
default IP address is changed to the assigned primary/second IP address of the interface.

Note: 

To access the Switch through a Web browser, the computer running the Web browser 

must have IP-based network access to the Switch. It is not suggested multiple user’s access to 
the web browser. The performance of web display would be affected.

Warning: Since the lower hosts under the layer 3 interface can access the switch by default 
gateway IP address.  Please remember to change the user name and password in your first 
login. Otherwise, the users can easily access the management interface and change the 
settings. It obeys the common security concern

2. Command Line Console Interface Through the Serial Port or Telnet

You can also connect a computer or terminal to the serial console port or use Telnet to access 
the Switch. The command-line-driven interface provides complete access to all switch 
management features. The RS-232 DCE console port is for setting up and managing the 
Switch via a connection to a console terminal or PC using a terminal emulation program. The 
default baud rate is 115,200, N, 8, 1.

Attention! To avoid system damage caused by sparks, please DO NOT plug in power 
connector when power is on.

The product is in compliance with Directive 2002/95/EC and 2011/65/EU of the European 
Parliament and of the Council of 27 January 2003 on the restriction of the use of certain 
hazardous substances in electrical and electronics equipment(RoHS Directives & RoHS 2.0).
