ISO Installation Guide


The aim of this guide is to provide assistance with the installation of jetNEXUS ALB-X appliance on your own hardware.

Download and create CD-ROM

Please download the latest ISO package from our FTP site here or our dropbox here

You can use your default CD burner application to burn the ISO image to a CD-ROM.

Note the hard disk will be completely wiped and reformatted as part of the install process.

CPU 2 Core 4 Core 12 Core
Memory 2GB 4GB 8GB
Disk Space 80GB (SDA) 120GB SSD (SDA) 120GB SSD (SDA)
Network Ports 2 Intel/Broadcom 2-4 Intel/Broadcom 2-8 Intel/Broadcom


Boot your server hardware from the newly created CD-ROM

The server will boot to the edgeNEXUS install screen


Type “jetnexus” and hit enter as per the on screen instructions.


The install process will start, giving you time for a coffee break.


You should then see and status bar indicating progress


Once the CD-ROM is ejected, the server hardware will reboot.

Congratulations you now have a jetNEXUS ALB-X load balancer.

Please refer Basic Configuration to assign an IP Address and log on to the GUI.

Basic Configuration

First Boot

Please ensure you have plugged in a live ethernet cable into eth0. On first boot the jetNEXUS ALB-X will try and obtain an IP address using DHCP. If there is no DHCP server present it will boot with it’s default IP address of On subsequent boots DHCP is disabled.

You now have three ways to setup your jetNEXUS ALB-X. The simplest way to initially configure your jetNEXUS ALB-X is via the edgeNEXUS Discovery Application.

edgeNEXUS Discovery Application

You can obtain the edgeNEXUS Discovery Application from here

edgeNEXUS Discovery is designed to make the initial configuration of the jetNEXUS ALB-X easy. The application can be installed onto a desktop and will scan the local network for edgeNEXUS devices. Please ensure the jetNEXUS ALB-X and the computer that is running jnDiscovery are on the same network. Once found, essential information such as an initial management IP address can be easily assigned.

How to use edgeNEXUS Discovery

Copy the edgeNEXUS application onto your desktop and run the installation. After the installation is complete double click on the Discover Icon to launch the edgeNEXUS discovery application.


The edgeNEXUS Accelerating Load Balancer Discovery will then open, showing you a list of edgeNEXUS appliances in your network.

Right click on the on device you would like to configure and select “configure”.


A message box like the following below will then pop up. Note this ALB-X has not been able to find a DHCP serer so has assigned the default IP Address of


You will be prompted for the following information:

IP Address:

The management IP address of the jetNEXUS ALB-X.

Network Mask:

The Network Mask of the jetNEXUS ALB-X management IP

Configuration Port:

The Configuration Port of the secure Graphical User Interface (GUI)


The Default Gateway. This is needed to gain access from browsers not on the local subnet.

Server Ref:

A name to identify the jetNEXUS ALB-X

In this example we have configured the following details:


Once you click on the Apply button you will be prompted for the password:


The default password is: jetnexus

Your Configured device with the new IP,Subnet and ServerRef will now show in the discovery screen.


Double click on the ALB you would like to configure and it will load the web admin in a browser:


Please ignore the warning and click “Continue to this website”. This will take you to the GUI for further configuration.

Command Line

Login Details

Default username= admin
Default password = jetnexus

First Boot – Manual Network Details

Upon first boot you will have a 10s opportunity to interupt automatic assignment of IP details via DHCP
To interupt click into the console and press any key
You can then enter the following details manaully
IP Address
Subnet Mask
DNS Server


First Boot – DHCP successful

If you do not interrupt when prompted then your jetNEUXS ALB-X willl then try to conntact a DHCP server to assign it’s network details
If contact is successful then your machine will be assign the following details
IP Address
Subnet Mask
Default Gateway
DNS Sever
These changes will survice after reboot and dont need to be configured again on the GUI

First Boot – DHCP Fails

If you do not have a DHCP server or the connection fails then the IP Adress will be assigned
The IP address will increase by 1 untill a free address is found
If is already assigned to the network then it will assign and so on

Change the Management IP Address


Change the Subnet Mask for eth0


Assign a Default Gateway


Check the Default Gateway has been added


You should now be able to access the Graphical User Interface (GUI)

Default GUI address = https://
Default Secure port = 443
Default Username = admin
Default Password = jetnexus
