ALIF: Accessing an Endpoint (TX or RX) Directly


When an Endpoint is under the control of AIM, it is the AIM that manages its configuration and can upgrade its firmware. The web interface on the endpoint will only show you basic information such as its IP addresses and firmware version. No configuration is possible in this mode.

Reasons for making a direct connection to an Endpoint: -

The first step to connecting directly to an Infinity endpoint is to ensure its factory reset, an endpoint that is under AIM control can not be configured directly. This will revert the endpoint to its default IP addresses. The second step is to find a host computer with a network adapter that ideally supports 1Gbit network speeds.

The proceeding information will tell you the default IP addresses that are assigned to each network port, determine which ports are available by endpoint model and their network access speeds. This is followed by an example of how to connect using Windows 7. Whilst the setup procedure may differ on other operating systems, the process is essentially the same.

A new or factory reset endpoint are automatically assigned one of the following default IP addresses.

Models: ALIF4021T/R


You can only use the 1Gb Copper OR the SFP network ports. You can not use them simultaneously. If an SFP module is inserted, the unit will assume that you wish to use the port, even if the SFP module is not connected to a cable,

A new or factory reset endpoint are automatically assigned one of the following default IP addresses.

Model Port 1
Port 2
OR Port 3
Port 4
Transmitter(TX) OR
Receiver(RX) OR


Models: ALIF4001T/R


A new or factory reset endpoint are automatically assigned one of the following default IP addresses.

Available Network Ports


The management port is only available when using the endpoint in a point to point mode. For security, it is disabled if the endpoint is under AIM Control.

Not all Infinity Endpoints have the same network ports, the first generation only had a single network port. The table below shows the network port availability for each model variant.

Model RJ45 Port(s) SFP Port(s) Management Port
ALIF1000R & ALIF1000T 1 1
ALIF1002R & ALIF1002T 1 1
ALIF2000R, ALIF2000T & ALIF2002T 2 1
ALIF2020R & ALIF2020T 2 1
ALIF2112T 2 1
ALIF100T 1 0
ALIF101T 1 0
ALIF4021R & ALIF4021T 2 2


Network Speed

Each network port has different speed capabilities. When connecting to one of the ports, make sure your host computers network adapter supports the speeds shown.

Example Procedure using Windows 7

The following example will show you how to configure a Windows 7 PC to access an Infinity ALIF2000R,


You will need the following equipment:-

  • A host computer with a 1Gb network adapter
  • Windows 7 (or above)
  • A network cable


Connecting the network cable

  • Using either a regular straight through or cross-over network cable, connect it from the host computer to the System port on the Infinity Receiver.

Configuring the network adapter

  • Open Network Connections by selecting the Start button, and then selecting Control Panel. In the Search box, type adapter, and then, under Network and Sharing Center, select View network connections.

    Infinity EndpointDirectConnect1

  • Right-click the network adapter connection that you want to change, and then select Properties. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  • On the Networking tab, select either Internet Protocol Version 4 (TCP/IPv4) in the list and then select Properties.

    Infinity EndpointDirectConnect2

  • Before changing any of the settings on the Internet Protocol Version 4 (TCP/IPv4) Properties screen, if you are not familar with networking, make a note of the existing settings so that you can revert back to your previous configuration.
  • Changing the mode from Obtain an IP address automatically to Use the following IP address.
  • Enter an IP address in the 169.254.1.x network range. This must not be the same as the endpoints IP address. In the example picture below, I have used
  • Enter a Subnet Mask of
  • The gateway address is not required.

    Infinity EndpointDirectConnect3

  • Press the OK button to commit the change.
  • Open a web browser, in the address bar, type to open the web interface on the Infinity Receiver
  • The main web interface will open showing the System Configuration page.

    Infinity EndpointDirectConnect5

  • Now that you are connected to the endpoints web interface, you are able to perform a number of configuration functions such as firmware upgrades and network settings.
