BehaviorMeaning All signal LEDs are offThe device is currently operating in AP mode, or the device is powered off. The first LED is on & slowly blinkingThe device is in station mode and is currently scanning. All three LEDs are on & fast blinking The device is currently updating its modem firmware. This only happens at boot after a firmware upgrade. The first LED is on and not blinking The device is in station mode and currently connected to an AP with low signal strength. The first two LEDs are on, not blinking The device is in station mode and currently connected to an AP with medium signal strength. All three LEDs are on, not blinking The device is in station mode and currently connected to an AP with high signal strength. Ethernet port LEDs 2.5G ETH0: 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. 1G ETH1: The link light will turn on and blink when a link is established, and the PoE out light will turn on when PoE out is enabled in software. Powering your device Input Power i The input power should be 48VDC and a minimum of .5A (24W) is recommended. The TNA-30x can be powered two ways, either via: 1. The Power over Ethernet (PoE) port or via 2. The DC input terminal. 10/20/22, 10:43 AMTNA-30x Operating Manual : Support & Learning Portal https://tachyon-networks.freshdesk.com/support/solutions/articles/67000670226-tna-30x-operating-manual3/8 Both powering methods should not be used at the same time. The input power should be 48VDC in both cases and a minimum of .5A (24W) is recommended. Although not recommended, a lower input voltage may be used (as low as 24VDC). However, there are two main limitations when using a lower input voltage: The cable run should be as short as possible and the use of larger gauge cable such as CAT6+ is highly recommended. On longer cable runs, the voltage drop will be higher due to the higher current needed to meet the needs of the radio. The PoE out is current-limited to .5A. At 24VDC, this is insufficient power for a second TNA-30x. Output Power The TNA-30x has the ability to send passive PoE out of the 1Gbps port to power another device using the input power provided to the TNA-30x. 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-30x, care should be taken to ensure there is adequate power supply to power both the TNA-30x 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. 10/20/22, 10:43 AMTNA-30x Operating Manual : Support & Learning Portal https://tachyon-networks.freshdesk.com/support/solutions/articles/67000670226-tna-30x-operating-manual4/8 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 (https://tachyon-networks.freshdesk.com/support/solutions/articles/67000659775-tna-30x- web-ui-manual-v1-10-3-) for details about each setting, or continue reading below about how to make a link. Making a link By default, the TNA-301 is configured to operate in AP mode with the SSID tachyon-ptmp, and the TNA-302 is configured to operate in station mode with the same SSID. This mea…
