FAQ - MetroLinq - How do I download the Troubleshooting Logs?

Upon contacting support for assistance, you may be asked to retrieve the troubleshooting logs. These files contain the configuration, link, and log information often needed to discover the root cause of a problem. Below are the steps to retrieving these files. From the web GUI 1. Navigate to "System". 2. Select "Maintenance". 3. Click on the "Troubleshooting Log" button to download the files.

Click on the "Live Actions" drop-down menu. 4. Select "Fetch troubleshooting File". 5. Once the troubleshooting file task has been started, navigate to "Maintenance" in the Device Menu. 6. Click on "Download file".

FAQ - MetroLinq - Does MetroLinq support VLAN?

Yes, MetroLinq will allow VLAN traffic to pass through, and the MetroLinq also has a Management VLAN option that can be enabled in the Network -> Internet Settings. Note that the MTU size must be increased accordingly.

FAQ - MetroLinq - Does MetroLinq require Line-Of-Sight between devices?

Yes, MetroLinq requires Line-Of-Sight for the link to work properly.

FAQ - MetroLinq- Can I reset my Metrolinq to factory defaults via SSH?

Yes, you can reset your MetroLinq to factory defaults via the SSH by: 1. SSH into the device with your administrator user name and password (default pair is "root", "admin123" respectively). 2. Use the command "reset_to_defaults.sh -y" to reset your device.

FAQ - MetroLinq - What are the channel bandwidths supported by the MetroLinq's 60 GHz and 5 GHz radios?

For the 60 GHz radio, we support 2000MHz channels. For the 5 GHz radio, we support 20, 40, and 80 MHz channels.

FAQ - MetroLinq - What are the antenna beam-widths for the MetroLinq product line?

The antenna Beamwidths are: - 1 degree(s) for ML-60-35-XX - 3 degree(s) for ML-60-19-XX - 30 degree(s) for ML-60-30-18-XX -120 degree(s) for ML- 2.5G 60-BF-18

FAQ - MetroLinq- Do I need the aiming scope for my MetroLinq?

While not required, the MetroLinq Alignment Scope, ICC-SCOPE-9X50, significantly lessens the challenge of antenna alignment by providing accuracy during deployments, installations, and ongoing operations. Initial antenna position is critical during MetroLinq deployments and upgrades alike. The MetroLinq Alignment Scope saves time and money by helping to eliminate costly site re-visits and re-climbs, and is therefore highly recommended, especially for longer links.

FAQ - MetroLinq- What is the Fresnel Zone for the 60 GHz MetroLinq radio?

The Fresnel Zone represents a series of regions in which surfaces will cause a reflected wave, phase shifted by some amount, to constructively or destructively interfere with the desired Line-Of-Sight (LOS) signal at the receiver. These concentric ellipsoidal regions (F1, F2, F3, etc) of radius R -- the first (F1) having the smallest R -- are centered on the direct transmission path between two radios (Figure 1). The total phase difference between the line of sight signal and the reflected signal is determined by factors such as the shape and properties of the obstruction as well as the polarization of the incident wave. Additionally, obstructions can cause diffraction and other undesirable effects. The higher the Fresnel Zone number, the larger R is, the farther a reflected signal travels before interfering, and therefore the weaker its effect is. We are thus mostly concerned about F1. If a significant portion of F1 is obstructed, the signal at the receiving antenna can be greatly attenuated. A general rule of thumb is that to avoid the significant signal blockage, diffraction or multi-path attenuation (for your link to behave as LOS), you need at least 60% of F1 clear of obstructions, where "60% of F1" is defined as a narrower ellipsoid with a radius that is 60% of the radius of F1.

FAQ - MetroLinq - What SNMP versions are supported?

SMNP v1 and v2.

FAQ - MetroLinq- What is the temperature range for MetroLinq radios?

Between -40 °C to +70 °C.

FAQ - MetroLinq - What is the maximum transmit power?

The absolute maximum values are 14 dBm (25mW) @ 60 GHz and 28 dBm (630mW) @ 5 GHz, but the transmit power available to a particular user may be governed by his/her country's regulations.

FAQ - MetroLinq- Can I use the second GE port of the ML for traffic purposes?

The second Ethernet port is bridged to the 60 GHz interface, but not the other Ethernet port. You can therefore pass traffic over the link, but you will not be able to see devices connected to the Eth0.

FAQ - MetroLinq- Can I use any ML device as a STA in a PTMP setup?

Yes. Typically the client devices for the PtMP scenarios are the models ML-60-35 and ML-60-19.

FAQ - MetroLinq - What is the maximum cable distance between the PoE injector and the MetroLinq?

The maximum recommended distance is 100 m using Cat 5e.

FAQ - MetroLinq- What separation distance I have to give to my MetroLinq radios installed on the same pole?

We recommend a separation of 0.5m/1.6ft.
