DC power input for JetNet 5428G-2DC. The front power switch can switch off all the
power input at the same time.
JetNet 5428G-AC AC Power Input
Connect the attached power cord to the AC power input connector, the available AC
power input is range from 90-264VAC.

8
JetNet 5428G-2DC DC Power Input
The suggested power input is 24/48DC, the available range is from
18-75VDC.
Follow below steps to wire JetNet 5428G-2DC redundant DC power
inputs.
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. DC1 and DC2 support polarity reverse protection functions.
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 would not damage
the switch. Incorrect wiring can not power on the switch.
2.3 Wiring Digital Output
JetNet 5428G-AC provides 1 digital output, also known as Relay Output. The relay
contacts are energized (open) for normal operation and will close for fault conditions. The
fault conditions include power failure, Ethernet port link break or other pre-defined events
which can be configured in JetNet 5428G UI.
2.4 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.

9
For AC input, the 3pin 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.
2.5 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.
Straight-through Cabling Schematic
Cross-over Cabling Schematic
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:

2.6 Wiring Fiber Ports
Small Form-factor Pluggable (SFP)
The SFP ports accept standard Gigabit MINI GBIC SFP transceiver. But, to ensure

10
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 not certificated by Korenix. The certificated SFP transceiver includes 100Base-FX
single/multi mode, 100/Gigabit BIDI/WDM, 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. The SPF cage is 2x1 design, check the
direction/angle of the fiber transceiver and fiber cable when
inserted.
Below figure is the SFP plug-in and SFP Fiber Cable Plug-in Example.
Note: This is a Class 1 Laser/LED product. Don’t stare at the Laser/LED Beam.
2.7 Wiring Gigabit Combo Ports
JetNet 5428G series includes 4 RJ-45 Gigabit Ethernet ports. The speed of the gigabit
Ethernet port supports 100Base-TX and 1000Base-TX. JetNet 5428G equips 4 Gigabit
SFP ports combo with Gigabit Ethernet RJ-45 ports. The speed of the SFP port
supports 100MB and 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.)
While the SFP transceiver is plugged, the Fiber port has higher priority than copper
port and moved to the Fiber mode automatically.
2.8 Wiring RS-232 Console Cable
Korenix JetNet 5428G attaches one RS-232 RJ-45 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

11
buy a new one. The Pin assignment spec is listed in the appendix.
2.9 Rack Mounting Installation
The Rack Mount Kit is attached inside the package.
2.9.1 Attach the brackets to the device by using the screws provided in the
Rack Mount kit.
(The picture is JetNet 5628G, the mounting method is the same.)
2.9.2 Mount the device in the 19’rack by using four rack-mounting screws
provided by the rack manufacturer.
(The picture is JetNet 5628G, the mounting method is the same.)
When installing multiple switches, mount them in the rack one below the other.
It’s requested to reserve 0.5U-1U free space for multiple switches
installing in high temperature environment. This is important to disperse
the heat generated by the switch.
Notice when installing:
Temperature: Check if the rack environment temperature conforms to the specified
operating temperature range.
Mechanical Loading: Do no place any equipment on top of the switch. In high
vibration environment, additional rack mounting protection is necessary, like the flat board
under/above the switch.
Grounding: Rack-mounted equipment should be properly grounded.

3 Preparation for Management
JetNet 5428G Rackmount Managed Switch provides both in-band and out-band
configuration methods. You can configure the switch via RS232 console cable if you
don’t attach your admin PC to your network, or if you lose network connection to your
JetNet 5428G. This is so-called out-band management. It wouldn’t be affected by
network performance.
The in-band management means you can remotely manage the switch via the network.
You can choose Telnet or Web-based management. You just need to know the device’s
IP address and you can remotely connect to its embedded HTTP web pages or Telnet
console.
Following topics are covered in this chapter:
3.1 Preparation for Serial Console

web-browser such as Microsoft Internet Explorer, or Mozila, to configure and interrogate
the switch from anywhere on the network.
Before you attempt to use the embedded web interface to manage switch operation,
verify that your JetNet 5428G Series Rackmount Ethernet Switch is properly installed on
your network and that every PC on this network can access the switch via the web
browser.
1. Verify that your network interface card (NIC) is operational, and that your operating
system supports TCP/IP protocol.
2. Wire DC power to the switch and connect your switch to your computer.
3. Make sure that the switch default IP address is 192.168.10.1.
4. Change your computer IP address to 192.168.10.2 or other IP address which is
located in the 192.168.10.x (Network Mask: 255.255.255.0) subnet.
5. Switch to DOS command mode and ping 192.168.10.1 to verify a normal response
time.
Launch the web browser and Login.
6. Launch the web browser (Internet Explorer or Mozila Firefox) on the PC.
7. Type http://192.168.10.1 (or the IP address of the switch). And then press Enter.
8. The login screen will appear next.
9. Key in user name and the password. Default user name and password are both
admin.
Click on Enter or OK. Welcome page of the web-based management interface will then
appear.

15
Once you enter the web-based management interface, you can freely change the
JetNet’s IP address to fit your network environment.
Note 1: IE 5.0 or later versions do not allow Java applets to open sockets by default.
Users have to directly modify the browser settings to selectively enable Java applets to
use network ports.
Note 2: The Web UI connection session of JetNet 5428G will be logged out
automatically if you don’t give any input after 30 seconds. After logged out, you should
re-login and key in correct user name and password again.
3.2.2 Secured Web Interface
Korenix web management page also provides secured management HTTPS login. All
the configuration commands will be secured and will be hard for the hackers to sniff the
login password and configuration commands.
Launch the web browser and Login.
1. Launch the web browser (Internet Explorer or Mozila Firefox) on the PC.
2. Type https://192.168.10.1 (or the IP address of the switch). And then press Enter.
3. The popup screen will appear and request you to trust the secured HTTPS
connection distributed by JetNet 5428G first. Press Yes to trust it.

16
4. The login screen will appear next.
5. Key in the user name and the password. The default user name and password is

2. Type the Telnet 192.168.10.1 (or the IP address of the switch). And then press
Enter
3.3.2 SSH (Secure Shell)
Korenix JetNet 5428G also support SSH console. You can remotely connect to the
switch by command line interface. The SSH connection can secure all the configuration
commands you sent to the switch.
SSH is a client/server architecture while JetNet 5428G is the SSH server. When you
want to make SSH connection with the switch, you should download the SSH client tool
first.
SSH Client
There are many free, sharewares, trials or charged SSH clients you can find on the
internet. Fox example, PuTTY is a free and popular Telnet/SSH client. We’ll use this
