Powering your device


Input Power


i  Important Notes

  • The input power should be 48VDC and a minimum of .5A (24W) is recommended.  
  • TNA-303X devices do support active PoE (802.3at, etc), unlike the TNA-301 and TNA-302

The TNA-303X can be powered via 38-57V Active PoE-In into the ETH0 port.


Output Power


The TNA-303X has the ability to send passive PoE out of the 1Gbps port to power another device using the input power provided to the TNA-303X.   These settings can be found under the Network/Ethernet PoE Out section of the Web UI.


The output voltage is the same as the input voltage and supports a maximum of .5A of current (24W total).


!   Warning: when using the PoE out feature on the TNA-303X, care should be taken to ensure there is adequate power supply to power both the TNA-303X and the secondary device.   The supplied PoE injector may not be adequate to power both devices and may result in unstable operation.

!   Warning: passive PoE out on the 1Gbps port can damage non-PoE devices.  Do not connect non-PoE devices to the 1Gbps port when PoE out is enabled.

Device access for initial configuration


i  You will need a modern web browser in order to access the device's Web UI to configure your device. 

  1. First, power on the device.  You can do this by using the DC input terminal or by using the included PoE adapter.  If using the PoE adapter, plug the power cable attached to the 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 2.5G ETH0 PoE-in port.

  2. Connect your laptop’s ethernet cable into either the data port of the PoE adapter (2.5G) or the ETH1 (1G) port on the device, in order to give your laptop or device connectivity.  By default, DHCP client is enabled on the main management network bridge of the device.  If your device cannot obtain an IP from an upstream DHCP server, it will fall back to 192.168.1.1, unless otherwise configured.

  3. Log in to your device's local web UI in your web browser at the DHCP-assigned IP, or the fallback IP previously mentioned, 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.

  5. Select an antenna kit (if using one) under the Wireless settings to ensure proper operation.


Making a link


By default, the TNA-303X 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-303X 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. The amount of aiming required to make a link will depend on the antenna kit attached to your TNA-303X.  You can download the STEP file for a 3D printable physical aiming tool here, which attaches to the antenna kit.

  4. If you're using an antenna kit in station or PTP modes, you may want to lock the radio to the boresight beam in order to keep the radio from beamforming and jumping to a different beam.  You can enable this under the wireless settings.


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-303X 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-303X (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.

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:
