InfiLINK 2x2 / InfiMAN 2x2: Initial Link Configuration and Installation

03

PtP/PtMP link pre-configuration in the lab

Usually, before going into the field, it is recommended to pre-configure in the lab the InfiNet Wireless units to verify the link establishment. Therefore, let's take the units to be used for this course out of the package and place them on the table.


NOTE

  • A minimum set of requirements must be met during devices pre-configuration in the lab:
  • Make sure that devices are positioned in such a way so that they are not directed right at each other to prevent device damage.
  • In case of connectorized model configuration, it is recommended to connect the two devices in the link directly, with RF cables and RF attenuators with attenuation of at least 40 dB for each polarization (installation\deinstallation of the RF attenuators and RF cables should only be performed when the devices are switched off).
  • In case an external antenna or the other unit in the link is connected to only one N-type connector do not switch on the unit.

Settings via the web interface

We shall perform the settings mentioned below for each unit of the link:

Task 1

Let's access each unit to the default IP address 10.10.10.1 with mask 255.255.255.0 via a web browser. Before, make sure the Ethernet port of the Laptop has an IP address assigned from the same subnetwork as the one for the unit (e.g., set 10.10.10.10 with mask 255.255.255.0).


NOTE

We assume that each unit used in this setup has not been configured before and runs with the factory settings.


Task 2

Use any letters or numbers for the initial authentication on each unit:

  • User Name: e.g., login.
  • Password: e.g., password.
Task 3

After the first login, let's configure a distinctive name for each unit and set a custom username and password. Go to the Basic Settings section, then to System Settings and configure:

  • Device Name (e.g., Master/Slave).
  • User Name (e.g., admin).
  • Password (e.g., admin).

NOTE

At the next login, type "admin" for the User Name and Password (if these are the credentials set before) to access the unit in the privileged mode.


Task 4

Let's change the management IP of each unit. Go to the "Basic Settings" section, then to Network Settings and change the default IP address of the ‘svi’ interface which is a logical interface used for remote management access in MINT switching mode (MINT switching mode is enabled by default).

Task 5

Let's upgrade each unit to the latest stable firmware version. Go to the Maintenance section and click on the "Check Latest Release" button. In case a new software version is available, click on the "Upgrade Firmware" to initiate the firmware upgrade process.

Before, make sure the laptop which is connected to the unit has an Internet connection, too. Otherwise, the manual firmware upgrade process should be performed.

Task 6

Let's configure the minimum needed radio parameters to establish the link.

At the unit named Master at step #3 above, go to the "Basic Settings" section, then to "Link Settings" and set this unit with:

  • Type: Master.
  • Polling: On.
  • Tx Power: e.g., -10 dBm (set the minimum value in the range, as currently, we are in the lab, and we don't need high output power anymore).
  • Node Name: e.g., Master (it is the same as the value set at Device Name if this was saved before).
  • Channel Width: e.g., 40 MHz.
  • Frequency: e.g., 4900 MHz.
  • Greenfield: On.

The rest of parameters remain with the default values.

At the unit named Slave at step #3 above, go to the Basic Settings section, then to Link Settings and set this unit with:

  • Type: Slave.
  • Tx Power: e.g., 5 dBm (set the minimum value in the range, as currently, we are in the lab, and we don't need high output power anymore).
  • Node Name: e.g., Slave (it is the same as the value set at Device Name if this was saved before).
  • Channel Width: e.g., 40 MHz.
  • Frequency: e.g., 4900 MHz.
  • Greenfield: On.

The rest of parameters remain with the default values.

Task 7

Let's apply all settings described above for each unit and after login let's go to the Device Status section, and check the link establishment at Link Statistics:
