1 Introduction
Thank you for purchasing the JetNet 3706/JetNet 3706f and welcome to the Korenix JetNet
3706/JetNet 3706f Series Industrial Web Managed Power over Ethernet (PoE) Switch User
Manual. The following topics are covered in this chapter:
1.1 Overview
1.2 Product Features
1.3 Package Checklist
1.1 Overview
JetNet 3706 and JetNet 3706f are Industrial Web Managed Power over Ethernet (PoE)
Switches, which include 4 Fast Ethernet RJ-45 ports with PoE injectors, 2 additional RJ-45
ports for JetNet 3706, and 2 additional Fast Ethernet fiber ports for JetNet 3706f. The
additional ports can connect with a High-End Switch or a PC workstation.
JetNet 3706/JetNet 3706f complies with IEEE802.3af PoE standards and IEEE802.3at
pre-standards. The maximum power forwarding ability ranges from 13.53w to 29.52w, based
on the voltage of the power input. JetNet 3706/ JetNet 3706f provides simple management
interface via Web browser to feature more network performances.
Network Redundancy
To obtain superior network forwarding performance, JetNet 3706 /JetNet 3706f adopts QoS
mechanism, Rapid Super Ring, and RSTP, which is in complies with IEEE802.1w-2004
edition to deliver a non-stop forwarding network.
High Power PoE
The excellent PoE power management features – IEEE 802.3af auto mode, IEEE 802.3af
manual mode, Ultra power mode for 30W high power device and PoE scheduling control can
enlarge your application and help saving power and more economic. The JetNet 3706/
JetNet3706f can apply with several of applications, such as PoE IP camera with PTZ function,
Industrial I/O device with PoE enabled.
DC24V /48V PoE System
For use with a DC 24V power source system, JetNet 3706/JetNet 3706f is equipped with a
dual-mode PoE powering mechanism which detects power voltage input in order to execute
the most beneficial powering and disconnecting process. This feature is suitable for
transportation systems or any applications without a DC 48V power source. Also, JetNet
3706/JetNet 3706f will calculate its power consumption using output current and voltage, and
will execute power budget limit protection.
High Power Forwarding Ability
According to IEEE802.3af Power over Ethernet standards, it specifies a 15.4w power budget
for PD systems. But, for some applications, 15.4w is not enough. For this purpose, JetNet
3706/JetNet 3706f provides 2 models of PoE powering mechanisms: IEEE802.3af, and High
JetNet 3706/JetNet 3706f Industrial Web Managed PoE Plus Switch 1

power pre-standard IEEE802.3at for 30W power budget. To recognize the PD classification ID,
JetNet 3706/JetNet 3706f is equipped with a powerful micro-processor for detection,
classification, powering and disconnecting purposes. JetNet 3706/JetNet 3706f automatically
powers the PD with a different PD classification ID. It can deliver a maximum of 120W output
with a DC 50V power input for ID number 4. For the IEEE802.3af standard PD, JetNet
3706/JetNet 3706f also supports a maximum of 61.4W power forwarding ability with DC 48V
power.
Quality of Service with WRR
In order to obtain superior transmission performance,JetNet3706/JetNet3706f enables QoS
function with 8:4:2:1 WRR forwarding mechanism. This feature ensures that real-time
services can be processed with high priority and without forwarding delays.
.

The right-side view of the JetNet 3706/ JetNet 3706f Industrial PoE Plus Switch consists of one
6 –pin terminal block connector and one chassis earth ground screw. The terminal block is for
JetNet 3706/JetNet 3706f Industrial Web Managed PoE Plus Switch 4

redundant power and relay output connections.
Protective Earth Ground
2.2 Wiring Power Inputs
Follow the steps below to wire the redundant power of JetNet 3706/ JetNet 3706f.
Power 1
V+ V-
Power 2
V+ V-
Not Used
1. Insert positive and negative wires into V+ and V- contacts respectively in the terminal
block connector
2. Tighten the wire-clamp screws to prevent DC wires from becoming loose.
3. Power 1 and Power 2 support power redundancy and polarity reverse protection
functions.
4. The power input ranges from DC 24~50V.
5. Positive and negative power system inputs are both accepted, but Power 1 and Power 2
must apply the same mode.
Note Please be sure to turn off input and load power, and to unplug the power terminal block
before making wire connections. Otherwise, your screwdriver can inadvertently short your
terminal connections to the grounded enclosure.
Note Suitable electric wire ranges from 12 to 24 AWG.
Note If the 2 power inputs are connected, JetNet 3706/JetNet 3706f will be powered from the
highest connected voltage. The unit will alarm if there is a loss of power (either PWR1 or
PWR2).
2.3 Wiring Earth Ground
To make sure data transmission is working properly, the Chassis Ground must be connected to
the protective earth.
Note All line-to-ground transient protection circuitry will be disabled if chassis ground is not
JetNet 3706/JetNet 3706f Industrial Web Managed PoE Plus Switch 5

connected with the protective earth.
To ensure the system will not be damaged by noise or any electrical shock, we suggest making
a direct connection with JetNet 3706/JetNet 3706f and Earth Ground to avoid system damage
from electrical static discharge.
On the right-side of JetNet 3706/JetNet 3706f , there is one earth ground screw. Loosen the
earth ground screw with a screwdriver and tighten the screw after the earth ground wire is
connected.
2.4 Wiring Fast Ethernet Ports
JetNet 3706/JetNet 3706f is equipped 4 Power over Ethernet (PoE ) injectors with 30w
forwarding capability in ports 1~4. The fast Ethernet ports support 10Base-T and 100Base-TX,
full or half duplex modes. All of the fast Ethernet ports auto-detect signals from connected
devices to negotiate link speed and duplex mode. Auto MDI/MDIX allows users to connect to
another switch, hub or workstation without changing straight-through or crossover cables.
JetNet 3706f has 2 100Mbps fiber ports for multi-mode or single-mode fiber.
Note that crossover cables simply cross-connect the transmit lines at each end to the received
lines at the opposite end.
Straight-through Cabling Schematic Crossover Cabling Schematic
Note Ethernet cables use pins 1, 2, 3, and 6 of an 8-pin RJ-45 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 end of an Ethernet cable into any switch port and connect the other end to your
attached device. The LINK LED will light up when the cable is connected correctly. Refer to the
LED Indicators section for descriptions of each LED indicator. Always make sure that the
cables connecting the switch and all attached devices (e.g. switch, hub, or workstation) are less
than 100 meters (328 feet).
The wiring cable types are as follows:
10Base-T: 4 Pair UTP/STP Cat 3, 5e, 6 cable, EIA/TIA-568-B.2 100-ohm (up to100m)
100Base-TX: 4 Pair UTP/STP Cat. 5e, 6 cable, EIA/TIA-568-B.2 100-ohm (up to 100m)
