LINK TECHNOLOGIES PowerLink AT2 Battery PoE

Hardware Overview

•  Power Button on Top
•  48v and 24v buttons on the front of the unit
•  LCD screen to tell you the current status
•  Light on top
•  Power Over Ethernet LAN Port
•  USB-C Charging system 2A
•  USB Power Out

Quick Start

• Power-On Powerlink AT2 Device
•  Press the voltage you need to power your CPE
•  Use a short CAT5 cable to go between the LAN port on the PowerLink AT2 and the CPE.
•  Connect to www.linktechs.net SSID
•  The IP address should come from CPE (if you are configured for DHCP on your wireless device), or you will need to statically configure it.
•  Connect to your CPE using web/inbox or installation application.

Normally there is no need to login to the PowerLink unless you wish to do some kind of special configuration, things like change VLANs, SSIDs, security etc. Most of the time the unit will be completely pass-through, and transparent bridging. Most manufacturing applications prefer this.

Hardware

Top Features

•  LAN Port
•  Reset Button
•  USB-C Power Input
• Power Button
•  LED Light
•  USB with Power Out

Front Buttons/LEDs
The Pwr led tells you if the router is powered on. The Battery light will blink if the unit is low on charge or charging, it will be solid if the unit is finished charging. WiFi blink, when client are associated Eth blink, when Ethernet is connected

Functions

Top Button
This is the button on the top of the unit, next to the LAN and Power In port.

•  One-click – Turn on Router and WiFi Turn on AT2
•  One-click – Turn off Router and WiFi
•  Fast Double click – Turn off AT2
•  Long click button – Turn on/off LED Light

24V / 48V Button
The 24v button is Yellow in color and the 48v button is Red. Be sure your device supports 48v and/or 24v before plugging them in. The PowerLink does not have a method to detect what voltage should be applied, therefore, it will apply the voltage you select. Look on the screen for the current-voltage output.

•  One-Click – Enable POE out with selected voltage and Enable WIFI
•  One-Click – Disable POE out and disable WIFI
•  One-Click at boot button – Show Test

Reset Button
The reset button is to either perform a firmware update or to factory reset the unit. This is typically one of the major troubleshooting steps that

• Pressed during startup – firmware update
•  Pressed for 30 seconds – factory reset.

Yellow Battery LED Indicator
This indicator tells you when the unit is charging, and when it is completed charging. It also will tell you when a low battery condition is enabled.

•  While charging = Blinking LED
•  End of Charge = LED ON
•  In discharging = LED ON
•  Low Battery = Blinking LED

Timeout
If the PoE out is on and the power is lower than 2W, the unit turns off after 2 minutes. If only WiFi is on, it turns off after 15 minutes. You can remove this timeout from the configuration.

Display
The LCD displays a number of items, the battery level, the Current PoE Voltage going out the POE Ethernet port, and the milli-amp draw, as well as an ethernet status Icon. It also can tell you if your configuration script was successfully completed or if it failed.

•  Battery level

•  PoE voltage

•  Ethernet Status ICON

•  switched off – router off
  – ethernet at 100 Full Duplex
  – Problems with an ethernet cable

•  unplug – Cable Not Plugged In

•  Power delivered

•  config did – When the script is successful

•  config failed – When the script fails

Default Configuration
To connect to the device and change options, you can connect via web browser via http://192.168.1.69 or SSH to the same IP address. The default
IP Address: 192.168.1.69
Username: root password: Geva

To Automate the Preparation of CPEs
On the Powerlink AT, through ssh connection:

• /root/CpConf.sh                                   daemon for CPE configuration
• /root/OnCpScript.sh                           executed on the CPE for its configuration
• /root/system.cfg                                 copied on the CPE for its configuration
• /root/icons.sh                                  daemon that controls icon on TFT

On HTML page of router - > System -> Startup -> Local Startup iperf -s&
/root/icons.sh &

/root/CpConf.sh &

•  Remove comment (#) on the last line, to enable auto CPE conf.
•  Customize OnCpScript.sh for your requirement.
•  Copy your CPE configuration file, system.cf g
• Examples work on the Ubiquiti AirOs CPE

Web Interface

You can access the web interface by browsing 192.168.1.69. The username is root and the password is either link techs or gets VA.

Status
The tight menu gives you the status page. This includes an overview, Firewall, routes, logs, processes, and graphing.
The Status page gives you Hardware, Firmware versions, and uptime.

The network section tells you what is in use and connected to the device.

Interface / Bridge
Under Network → Interfaces, you have the option to configure new interfaces and/or edit the existing ones. The default should be LAN, this is a brand bridge group.

By clicking edit, you can edit the LAN interface, this will bring up the following menu options:

Here, you have options to select what protocol you wish, this could be used on the ethernet or any other interface. The default option is static address, where the br-lan is statically configured.

Other options include; PPP, DHCP Client, or PPPoE. I would always recommend that you bring up the default interface statically as well as upon boot. NOTE, there is options here that can render the device not reachable, and then a factory reset would be the only option.

Under Physical Settings, you can tell that this interface is a bridge, enable STP and/or IGMP snooping, as well as select what interfaces you wish to bridge together. The image below is the default configuration.

DHCP-Server
Under Network → Interfaces, hit edit your interface and then you can go to DHCP Server. Here are your configurable options for DHCP Server.

Wireless
This section under status gives you the wireless access point, SSID, and encryption as well as the channel of radios0, this is the 2.4 GHz radio built into the PowerLink AT2. The radio1 would be if you have added the 5 GHz module into the unit.

Here you have options to disable the radio interface, as well as set your network mode, channel, and width. You also have the option to select auto channel if you prefer.

In advanced settings at the top, you can select the country you are operating in, therefore it will keep the power levels to the max your country supports. NOTE, if you have legacy 802.11b devices, you will need to check the box to allow 802.11b devices, else you can uncheck this. Please test to verify you are not using a legacy device.

Under General Setup, you have options for what mode you wish to operate in, Access Point being the most common. Other options include client, ad-hoc, Monitor, and various WDS modes.

Changing SSID
You will change your SSID by going to Network → Wireless → selecting edit on the radio you wish to modify, then it will be under General Setup. Here you have ESSID, this is your SSID that will appear, if you wish to hide it or change the network that this interface operates off of you can do it here.

Securing Wireless
Under Network → Wireless → Wireless Security, you have options to select what security mode you wish to operate in. WPA2-PSK is recommended. You will enter your network key under KEY

Isolating Clients
If you wish, you can click advanced settings under your wireless interface and select the check box to isolate clients.

VLANs
Under the Network → Switch, you have the ability to add VLANs to your configuration. What VLAN ID and what tag or untagged port it should come from.

Firewall

Change Password
To Change the PowerLink ATs default password, go to System → Administration. Here you can change the default password.

DHCP and DNS

Iperf3
Iperf3 is always running. You can run the following command:

Samba3 and USB flash key
USB flash memory FAT32 mounted in /mnt/usbkey Android and Linux shared as:
192.168.1.69/usbkey
Samba3 does not work with windows 10, but you can enable it. (Search in google)

Repository:
If you set the working gateway, repository work, and you can add the modules you need, for example, to enable
SAMA, GSM dongle, or other drives, the flash-free is about 1Mb.
