Introduction
The JetNet 5428G Series, the 19-inch 24+4G Managed Ethernet Ring Switch includes
JetNet 5428G, JetNet 5428G-DC and JetNet 5428G-2G-2FX.
The JetNet 5428G/5428G-DC, is equipped with 24 10/100 Base-TX ports plus 4 Gigabit
RJ45 / MINI GBIC combo ports. The 5428G-2G-2FX is equipped with 24 10/100 Base-TX
ports, 2 100M/Gigabit SFP plus 2 Gigabit RJ45/SFP combo ports. JetNet 5428G Series is a
special design for control rooms where high-port density and performance are required. The
2/4 Gigabit Combo port design allows 10/100/1000 triple speed of copper ports, and the SFP
ports accept all types of Gigabit SFP transceivers, including Gigabit SX, LX, LHX, ZX and XD
for several connections and distances. Additionally, the last 2 SFP ports of JetNet 5428G-2G-
2FX can support 100Base-FX and Gigabit SFP transceivers.
The device is mounted within the 19 inch rack, along with other 19 inch public
servers or other network devices. When the lower industrial switches are
aggregated to the JetNet 5428G, the 24+4G design allows connecting up to 12
100M rings plus 2 Gigabit rings. Each of the ring has its own ring redundancy
protection. This is a unique and Korenix patent protected ring technology.
JetNet 5428G is designed as a fan-less rackmount switch with low power consumption and
wide operating temperature. JetNet 5428G-DC, the DC input model, allows 24V (12-48V)
DC input. JetNet 5428G supports Jumbo frame featuring up to 9,216 bytes packet size

2.3 Panel Layout
The front panel includes RS-232 Console Port, System & Port LEDs, Fast Ethernet Port
Interfaces and Gigabit Combo Port Interfaces.
The console port chooses RS-232 DB-9 types. The pin arrangement is “Pin2: TxD, Pin3:
RxD, Pin5:GND”. Korenix attached the console cable within the shipped box.
In the Rear panel, there are 2 types power input connector applied to JetNet 5428G and
JetNet 5428G-DC.
JetNet 5428G/5428G-2G-2FX chooses standard AC plug as power input socket.
JetNet 5428G-DC chooses 4-pin terminal block as power input socket. Follow the V+, V-
indication in the rear panel to screw the power source.

operating temperature range. Do not
place any equipment on top of the
switch and please properly grounded.

Note 1: It is a good practice to turn off input and load power, and to unplug power terminal
block before making wire connections. Otherwise, your screwdriver blade can inadvertently
short your terminal connections to the grounded enclosure.
Note 2: The range of the suitable DC electric wire is from 12 to 24 AWG.
Note 3: Please follow the V+ and V- indicator to wire. Incorrect wiring can not power on the
switch.
1. Insert positive and negative wires into V+ and V- contacts
respectively of the terminal block connector
2. Tighten the wire-clamp screws to prevent DC wires from being
loosened.
3.Power 1 and Power 2 support power redundancy, one of it
failed, the other recovered.
4.Positive and negative power system inputs are both accepted,
but Power 1 and Power 2 must apply the same mode.
4. Power the unit and connect to network Cable
4.1 Wiring Power Inputs
JetNet 5428G AC Power Input: Connect the attached power cord to the AC power input
connector, the available AC power input is range from 90-264VAC.
JetNet 5428G-DC DC Power Input: The suggested power input is 24VDC, the available
range is from 12-48VDC.
Follow below steps to wire JetNet 5428G redundant DC power inputs.
4.2 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 5428G with Earth Ground.
For AC input, the 3 pin include V+, V- and GND. The GND pin must be connected to the
earth ground.
For DC input, loosen the earth ground screw by screw drive; then tighten the screw after
earth ground wire is connected.

4.3 Wiring Fast Ethernet Ports
JetNet 5428G includes 24 RJ-45 Fast Ethernet ports. The fast Ethernet ports support
10Base-T and 100Base-TX, full or half duplex modes. All the fast Ethernet ports will auto-
detect the signal from connected devices to negotiate the link speed and duplex mode.
Auto MDI/MDIX allows users to connect another switch, hub or workstation without
changing straight through or crossover cables.
Note that crossover cables simply cross-connect the transmit lines at each end to the
received lines at the opposite end.
Connect one side of an Ethernet cable into any switch port and connect the other side to
your attached device. The 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).
The wiring cable types are as below.
10Base-T: 2-pair UTP/STP Cat. 3, 4, 5 cable, EIA/TIA-568 100-ohm (100m)
100 Base-TX: 2-pair UTP/STP Cat. 5 cable, EIA/TIA-568 100-ohm (100m)
1000 Base-TX: 4-pair UTP/STP Cat. 5 cable, EIA/TIA-568 100-ohm (100m)
Note that 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:

4.4 Wiring Fiber Ports
Small Form-factor Pluggable (SFP)
The SFP ports accept standard Gigabit MINI GBIC SFP transceiver. But, to ensure
system reliability, Korenix recommends using the Korenix certificated Gigabit SFP
Transceiver. The web UI will show Unknown vendor type when choosing the SFP which is

4.5 Wiring Gigabit Combo Ports
JetNet 5428G series includes 4 RJ-45 Gigabit Ethernet ports. The speed of the gigabit
Ethernet port supports 10Base-T, 100Base-TX and 1000Base-TX. JetNet 5428G/5428G-
DC equips 4 Gigabit SFP ports combo with Gigabit Ethernet RJ-45 ports. The speed
of the SFP port supports 1000Full Duplex. The available gigabit SFP supports Gigabit
Single-mode, Multi-mode, BIDI/WDM single-mode SFP transceivers. (The 100Base-FX is
not supported in gigabit combo ports.)

4.6 Wiring RS-232 Console Cable
Korenix JetNet 5428G attaches one RS-232 DB-9 to DB-9 cable in the box. Connect the
DB-9 connector to the COM port of your PC, open Terminal tool and set up serial settings
to 9600, N,8,1. (Baud Rate: 9600 / Parity: None / Data Bit: 8 / Stop Bit: 1) Then you can
access CLI interface by console cable.
Note: If you lost the cable, please contact with your sales or follow the pin assignment to
buy a new one. The Pin assignment spec is listed in the appendix.
1.1 Go to Start -> Program -> Accessories -> Communication -> Hyper Terminal
1.2 Give a name to the new console connection.
1.3 Choose the COM name, and select the correct serial settings. The serial settings of
the JetNet 5428G are as below:
Baud Rate: 9600 / Parity: None / Data Bit: 8 / Stop Bit: 1
