Device I/O

The reset button is located under the screw, shown in the image below.

Meaning of device LEDs

Signal level LEDs

The signal LEDs are updated at a ~4 second interval.

Ethernet port LEDs

1G ETH0 (PoE-In): The link light will turn on when a link is established, and the power light will turn on once the device is supplied with power. 

Powering your device

Input Power

The TNA-303L-65 can be powered via 38-57V Active or Passive PoE-In into the ETH0 port.

Device access for initial configuration

1. First, power on the device.  Plug the power cable attached to the included PoE adapter into the wall.  Next, plug one side of an ethernet cable into the adapter’s POE port, and the other into the device’s 1G ETH0 PoE-in port.
   
   
2. To get connectivity: 
   • Option 1 (wired): First, connect your laptop’s ethernet cable into the data port of the PoE adapter (1G). By default, DHCP client is enabled on the main management network bridge of the device. You will need to pull up the UI at the DHCP-assigned IP address. If your device cannot obtain an IP from an upstream DHCP server, it will fall back to 192.168.1.1, unless otherwise configured. The device will be accessible on the additional "alternative local IP" of 169.254.1.1 as well.
     
     
   • Option 2 (wireless): Insert a supported Mediatek MT7610U USB Wi-Fi dongle into the device's USB port. Once inserted, the 2.4GHz radio will come up with an SSID of tachyon-mgmt<last 3 octets of device's eth0 mac> and can be accessed with the passphrase 00000000. All clients will get a DHCP address within the 192.168.5.x range and the UI will be accessible at http://192.168.5.1.
     
     
3. Log in to your device's local web UI from your laptop or mobile web browser using the default credentials of root/admin.  Please change the default user credentials after you login for the first time.
   
   
4. Go to the configuration settings tab via the main nav menu on the left in order to configure your device. Please refer to the full web UI manual for details about each setting, or continue reading below about how to make a link.

Making a link

By default, the TNA-303L-65 is configured to operate in station mode with the SSID tachyon-ptmp, and configured to use the encryption key value of 'passphrase'.  

This means once you power up a TNA-303L-65 with-in range of a factory-reset TNA-301, they should link up without any additional configuration (default channel is 5), and immediately start passing traffic.

For minimal setup, it is recommended to change the SSID to a unique identifier and to set a unique encryption key.  

In order for the devices to link together, the SSID, channel width, and encryption type/key must all match. 

To do to this, login to the Web UI, navigate to the wireless->60 GHz radio settings, and input the new settings on both devices (and subsequent client radios).  

Click save to apply the changes.  If the channel width or operation mode has been changed, it will require the device to reboot to take effect.

Other notes:

1. You can see the status of the link between the AP (or PTP master) and client (or PTP slave) on the dashboard page of the Web UI, as well as perform a speedtest across the link.  
   
   
2. There is an aiming tool located under the Tools menu of the Web UI which will report RSSI much faster than the dashboard does. This is useful to optimize the signal once a station is connected.  
   
   
3. You can download the STEP file for a 3D printable physical aiming tool here, which attaches to the back of the unit.

How to select channel parameters

Please use the link calculator and corresponding guide to determine the optimal target distance and channel(s) to use for your installation.  Also keep in mind that the 60 GHz frequency requires LOS and is affected by rain fade as well as significant oxygen absorption in the lower frequencies.

You can read more about half channel support here. 

Troubleshooting your link

Please take the following steps to troubleshoot any wireless links that have sub-optimal performance:

1. Check to see if the devices are running the latest firmware.  The latest firmware can be found here.
   
   
2. Check to see if the devices are within the coverage areas of each other and have line of sight to each other.
   
   
3. Check to see if the link parameters in use are capable to create a link as estimated by the link calculator.
   
   
4. If the devices are connected but the connection quality is poor, it could be due to a destructive reflection on the path.  To solve this, try moving your TNA-303L-STA station up or down, or left/right in small increments.  Up/down movements are generally more helpful in these cases assuming the reflection is from the ground plane (e.g. the ground, nearby rooftops in the path, etc.).  Changing the channel may also resolve this issue since different frequencies will have different channel characteristics.

The TNA-303L-65 (as well as most other PTMP devices operating in the 60GHz band) use a single carrier PHY for transmitting data.  Single carrier PHYs are more susceptible to destructive reflections than some other methods such as OFDM.

I'm still having trouble with my link, what do I do next?

Please collect the troubleshooting files for both sides of the link you're trying to make, and send them to us at support@tachyon-networks.com, along with any other relevant info you might have about your install such as:

1. A detailed description of your issue.
2. Link distance and any other hardware involved in the link.
3. Your rain region and expected RSSI of the link, based on results from the link calculator
4. Wireless speed test results (assuming a link can be made)
5. How you are powering the devices.
6. What other accessories (cameras, other radios, etc) are connected to the device, and how they're powered.
7. Relevant environmental details, such as how far off the ground the AP and STA(s) are installed, if there are any metal structures nearby, large bodies of water, etc. 

You can find the link to download a device's troubleshooting file from the menu located under the gear/settings icon in the web UI, in the upper right corner (see below screenshot under the "Updating firmware" section).

Quick Setup FAQs 

Why does the MCS rates of my link seem lower than it should be given a solid RSSI? 

You will need to run traffic over your link in order the data rates to modulate to the higher values.

Why doesn't the speedtest cause a spike in traffic on the throughput graph? 

The speedtest only sends a very quick burst of packets, so won't have that much of an impact on the overall throughput graph results.

Updating firmware 

Firmware can be updated in two ways:

1. Via the web UI: Download the latest firmware from our support site, and upload it via the web UI:
2. Via the RESTful API: You can script firmware upgrades via the API. Reference the Tachyon Networks RESTful API specs article for more information.
   
   

All TNA-303x series devices have two bootbanks.  In the event that a firmware upgrade fails (power flicker, etc) and the device cannot boot up, it will revert back to the firmware flashed on the previous bootbank.

Resetting your device

You can reset your device to factory defaults 2 ways:

1. Reset button: Find a paperclip, or something similar, and use it to press and hold the physical reset button on the device for 20 seconds or more. This will not have any affect if the reset button is disabled in software.
   
   Important: Make sure that the unit is fully booted up (~5 mins) before attempting to reset the device via the reset button.
    
2. Via the web UI: Once you're logged in, click the gear icon in the upper right corner, as shown below, and you'll see the reset option:
