ComponentDescription

  • 2 x Outdoor Units
    • Supplied


  • 2 x Indoor power supply IDU-BS-G(60W)
    • Supplied


  • 2 x Power Cord
    • Supplied


  • 1 x Laptop
    • Not Supplied

In the lab and later on site perform connect the connections as devices as indicated below:

  • Connect laptop to the IDU port labeled as "IN" with an Ethernet cable.

  • Use another Ethernet cable to connect "GE0" port at the ODU to the IDU port labeled as "OUT".

  • Use power cord to connect the IDU to using AC mains.

titleFigure- Connection Scheme

Warning
titleCAUTION

Before supplying power to the Um models an external antenna or RF terminators with 50 Ohms resistance must be connected to both N-type connectors.

During laboratory testing, it is allowed to directly connect two devices with RF cables without antennas with the mandatory use of attenuators with attenuation of at least 40 dB for each polarization. Switching off/on the attenuators and RF cables should only be performed when the devices are in the off state.

In case the antenna, attenuator or terminator is connected to only one N-type connector do not switch on the device.

PLEASE NOTE THAT VIOLATION OF THE ABOVE REQUIREMENTS VOIDS THE WARRANTY.

After the physical connections are completed, perform settings of configure each unit as described below.

Units settings can be performed via:

...

Settings via web interface 
Anchor
Settings via web interface
Settings via web interface

Step 1

Access the unit to the default IP address 10.10.10.1 with mask 255.255.255.0 via web browser.

Make sure that the Ethernet port of the Laptop has an IP address assigned from the same

network class

subnetwork as the one for the unit (for example, set 10.10.10.50 with mask 255.255.255.0).

Step 2

Use any letters or numbers for initial authentication, for example:

  • User name: "login".
  • Password: "password".
Note
titleNOTE
After the initial login to the units, it is recommended to change the user and password to more secure permanent values

Make sure to set strong passwords before running the units in production.

Step 3
Enter

Log in to the

unit

Web GUI.

Initially the status of the radio link is DOWN like below.

Step 4

Upgrade the units to the

newest available

latest stable firmware version.

Note

For more details go to the section "Maintenance".


Step 5

Perform radio settings.

Go to the "Radio" section and set the following parameters:

  • Node Type (one unit must be set to Master and the other one to Slave).
  • Link ID.
  • Channel Width.
  • Frame period.
  • Max Distance.
  • Center Frequency.
  • Maximal Transmit Power
. Note
titleNOTE
Make sure that both units are configured with maximum Tx power
  • .

Note
titleNOTE

The detailed description for each radio setting can be found in the section "Radio".

Warning
titleCAUTION

 Please note that the following parameters must have the same values at each of the two units in the PtP link. Otherwise the wireless link

between them

won’t be established:

  • Center Frequency
  • Channel Width
  • Frame Period
  • Max Distance
  • Short Cyclic Prefix
  • Link ID
Step 6

Save the configuration, reboot both units and check if they link is up

after reboot

.

The link status should be UP and the radio statistics should indicate the capabilities and quality of the link.

Check the firmware version and upgrade the units to the

newest available

latest stable firmware version.

You can check firmware version via command:

Code Block

themeEmacs
xginfo version

Compare current version of the unit with version on official

of

a newer version is available

it is recommended to upgrade the firmware

we recommend upgrading.

In order to

synchronize

apply the

units settings, copy from one unit and paste to another the "Peer exported config" line shown in the

same settings to the another unit you should use the following command output "xg config -peer-exported"

Perform Initial Antenna Alignment

Step 1

Install both units on the pole and direct them at each other (more detailed information about units installation and antenna alignment is described in the section "Units Installing").

Step 2

Turn them on and make sure that the units subsystems are working properly. This can be done by LED indication.

Perform coarse alignment using built-in signal strength indicators.

Note
titleNOTE

 The The more indicators are on, the better wireless connection is established. The blinking indicator means an intermediate state. The more often the indicator blinks the higher level connection is established.

Step 4

Perform fine alignment using the "Alignment tool" available in the Web interface or "xginfo stat" output in the CLI. Try to  maximize CINR and RSSI readings. Please follow the detailed indications from section Antenna alignment for a proper antenna alignment.
