1. Introduction
Korenix JetNet 3810G Series is a power over Ethernet rail switch that is specially
designed for industrial or commercial applications. The following topics are covered
in this chapter:
1.1 Overview
1.2 Product Features

Korenix
JetNet 3810G(f)/ 3806G/ 3710G
1.1 Overview
JetNet 3810G series, Industrial Power over Ethernet (PoE) GbE Switches, are designed
with 8/ Fast Ethernet PoE ports and 2Gigabit uplink ports to ensure high-bandwidth
uplink connection for wide PoE markets. This series include JetNet 3810G/ 3806G/
3710G which are all compliant with IEEE 802.3af PoE standard to deliver maximum
15. Watts per port. For JetNet 3810G/ 3806G model, it integrates with Korenix
patented power boost technology- Input DC 12~2 V boosting to 8V built-in power
booster which is the best solution for the vehicle PoE applications with standard DC
8V power supply unavailable. For fiber Switch series such as JetNet 3810Gf, it
combines hot-swappable SFP fiber transceiver interfaces which can meet different
specifications of fiber cable for extending transmission distance.
To ensure the high quality of video data transmission, JetNet 3810G series not only
provide Gigabit bandwidth uplink for large image traffic, but also support QoS to
adjust the priority of data transfer. With the feature of Fault Relay, JetNet 3810G
series could automatically warn administrator if any abnormal situation happens. The
compact size with IP-30 rigid aluminum case allows JetNet 3810G series to be reliably
operated in -25~60℃ extreme environment.

2.2 Wirin the Power Inputs
JetNet 3810G(f)/3806G is a specific surveillance system used in vehicles. It accepts
12~2 V DC power input and boosts to 8V DC output for 802.3af standard PoE
devices.
JetNet 3710G without power boosting function accepts only 8V DC power Input.
IMPORTANT: Do make sure that different models must connect to the corresponding
supply voltage. Guarantee will not apply to the damage caused by wrong input
power.
1. Insert the positive and negative wires of your DC supply into the V+ and V-
contacts of the terminal block connector. The acceptable wire range is 12 to 2 AWG.

2. Tighten the terminal screws to prevent the DC wires from coming loose.
2.3 Wirin the Relay Output
JetNet 3810G(f)/3806G/3710G provide Relay Output. The relay contacts are
energized (open) for normal operation and will close under faulty condition such as
Ethernet port link break. The Relay alarm can be configured by DIP Switches.

2.4 Wirin Earth Ground
To ensure the system will not be damaged by noise or electric shock, we suggest
making a direct connection between the JetNet 3810G(f)/3806G/ 3710G and earth
ground to avoid system damage. (Please refer to the upside photo)
1. On the bottom of the JetNet 3810G(f)/3806G/ 3710G, there is one earth ground
screw.
2. Loosen the earth ground screw with a screwdriver
3. Tighten the screw after the earth ground wire is connected.
2.5 DIP Switches
10-Pin Dip switches are located on the bottom panel of JetNet 3810G(f)/ 3710G for
configuration purpose (6-Pin for JetNet 3806G). They are used to configure Port
Alarm to corresponding TX ports.

2.6 Wirin the Ethernet Ports
JetNet 3810G(f)/ 3806G/ 3710G Industrial Gigabit PoE Switch support 8/ RJ- 5 ports
with automatic MDI/MDI-X crossover, PoE Injector, and automatic 10/100Mbps data
rate sensing for 10Base-T or 100Base-TX connections. Automatic MDI/MDI-X
crossover allows you to connect to other switches, hubs, or workstations, without
regard to using straight-through or crossover cabling. For JetNet 3810G/ 3806G/
3710G model, the switch also provides two 10/100/1000 Base-TX uplinks.
Port 1 to port 8/ also provides Power over Ethernet function that delivers DC 8V
power through the spare pairs to power the PD.
The following figures depict the schematic diagram of straight-through and crossover
cabling. Note that crossover cables simply cross-connect the transmit lines at each
end to the receive lines at the opposite end.
Straight-through Cabling Schematic Cross-over Cabling Schematic
Note: that Ethernet cables use pins 1, 2, 3, and 6 of an 8-pin RJ 5 connector. The
signals of these pins are converted by the automatic MDI-X function, as shown in the
table below:
Pin MDI-X Signals MDI Signals
1 RD+ TD+
2 RD- TD-
3 TD+ RD+
6 TD- RD-
Connect one side of an Ethernet cable into any switch port and connect the other
side to your attached device. The green LNK LED will light up when the cable is
correctly connected. Refer to the LED Indicators section for descriptions of each LED
indicator. Always make sure that the cables between the switches and attached
devices (e.g. switch, hub, or workstation) are less than 100 meters (328 feet).

2.7 Wirin the Fiber Ports (only JetNet 3810Gf)
JetNet 3810Gf equips 2 gigabit SFP fiber ports. The speed of the SFP port supports up
to 1000Base-SX/LX. The SFP ports accept standard MINI GBIC SFP transceiver. But, to
ensure system reliability, Korenix recommends using the Korenix certificated
Gigabit SFP Transceiver. The certificated SFP transceiver includes 1000Base-SX/LX
single/multi mode ranger from 550m to 80KM. The way to connect the SFP
transceiver is to plug in SFP fiber transceiver fist. Cross-connect the transmit channel
at each end to the receive channel at the opposite end as illustrated in the figure
below.
Note: This is a Class 1 Laser/LED roduct. Don’t stare at the Laser/LED Beam.
Note: 100Base-FX SFP transceiver is optional and can be supported by different
settings
2.8 Connectin Powered Device (PD)
Port 1 to port 8/ provide PoE inject function with maximum 15. w ability to power
up the powered device use the straight or cross-over Ethernet cable.
The JetNet3810G(f)/ 3806G/ 3710G follow the IEEE802.3af Alternative B mode
connector assignment. The following table shows pin assignment of alternative A and
B for the PSE ( Power Source Equipment).

PIN Assignment of PSE
Be sure the twisted pair cable is bound with the standard RJ- 5 pin, especially the pin
, 5, 7 and 8.
If the RJ- 5 is bound with the wrong pin number, JetNet will not
recognize the PD and won’t forward DC 8V power to PD, since the
JetNet 3810G series switch following the Alternative B mode.
In the IEEE 802.3af standard documents, it indicates the PD should
support mode A and B, and only receiver power from either mode A or mode B.
The following table shows the RJ- 5 pin out for the PD.

JetNet 3810G series on the DIN-Rail
track.
1. Insert the upper end of the
DIN-Rail clip into the back of
the DIN-Rail track from its
upper side
2. Lightly push the bottom of the
DIN-Rail clip into the track.
3. Check if the DIN-Rail clip is
tightly attached to the track.
To remove the JetNet 3810G series
from the track, reverse the steps
above.
