Some steps include a link to more detailed instructions. 1. [Inspect the terminal](#inspection). 2. Open the cover on the back of the terminal, connect the dongle cable, and close the cover. 3. Turn on the terminal by connecting it to a power source. During startup the display turns on and off a few times. 4. Select **Configure network**. Then [connect the terminal to your network](#connect-to-network). 5. Select **Board the terminal**, select your store, and select **Confirm**. Boarding can take up to 30 minutes. If **Board the terminal** doesn't show, wait until the next synchronization with the Adyen platform (on average three hours) and try again. 6. [Test the connection with the Adyen platform](#test-psp-connection). 7. [Test the connection with your POS system](#test-cash-register-connection). When you have completed these steps, you are ready to process payments! ## Inspect the terminal Because payment terminals process sensitive card data, you must verify that the terminal you received is the correct one, supplied by Adyen, and has not been tampered with. 1. Verify that the shipping box containing the terminal has not been opened and that the tamper-evident security packing tape is intact. 2. If you have access to the Adyen [Customer Area](https://ca-live.adyen.com/), log in and under **In-person payments** > **Orders and returns** find the order for your terminal. Then: * Verify that the **serial number** (S/N) on the box is the same as in the Customer Area. * Using the **track & trace** link, track the order with the carrier to verify that they confirm having delivered the payment terminal. 3. Open the box, take the terminal out of the box, and verify that the **serial number** (S/N) on the terminal is the same as the serial number on the box. 4. Inspect the terminal for tampering. Check for missing screws, additional wires or labels, holes in the device, and anything inserted in or attached to any part of the terminal. If any of the above checks fails, contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) immediately. ## Connect to your network Connect your terminal to the internet so that it can communicate with the Adyen payments platform. Follow the instructions for the network connection you want to use: [Ethernet LAN](#connect-wired) or [Wi-Fi](#connect-wi-fi). ### Connect to Ethernet LAN * Connect an Ethernet cable to the Ethernet (LAN) port on the dongle.\ That is the port marked with **ETH** or this symbol: ![](/images/a/1/0/1/d/a101dc89519f0df8636ba5c49ba9f5ffd7f70696-ethernet-icon.png) Connecting the wrong type of cable to the Ethernet port or connecting the Ethernet cable to the wrong port (for example, the RS232 port) may severely damage the terminal. ### Connect to Wi-Fi 1. On the terminal display, select **Configure network**. 2. Select **Wi-Fi**. 3. Turn on the **Wi-Fi** toggle switch. 4. Select the **+** icon to add a network. The terminal scans for Wi-Fi networks. 5. Choose the desired network from the list and enter the Wi-Fi password, or select **Add manually** and enter the name (SSID) of the Wi-Fi network and the Wi-Fi password. 6. Select the check mark to confirm.\ The terminal sets the network as default automatically, and connects to it.\ You'll now see a Wi-Fi icon at the top of the display. #### After the terminal is boarded If you need to change Wi-Fi usage after the terminal is boarded: 1. Select **Settings** > **Network**. 2. Enter your [passcode](/point-of-sale/menu-access?tab=manage_passcodes_in_the_customer_area_1#manage-passcodes). 3. Select **Wi-Fi**. You can now: * Turn Wi-Fi on or off using the **Wi-Fi** toggle switch. * [Change IP settings](/point-of-sale/design-your-integration/network-and-connectivity/network-configuration#configuring-the-terminal-IP-address). * Add another network as described above. ## Test the payments platform connection Payments are processed on the Adyen payments platform. To test the connection with that platform: 1. Select **Settings** > **Diagnostics** > **PSP connection**. 2. Check if the **Status** is **Successful**.\ You can also **View results** and check if all items have a green check mark ![-white\_check\_mark-](/user/data/smileys/emoji/white_check_mark.png "-white_check_mark-").\ Do not worry if **Receiving data** has a red cross ![-x-](/user/data/smileys/emoji/x.png "-x-") and the result is **No Error**; the terminal successfully connected with our platform. ## Test the POS system connection To test the connection with your POS system: 1. Select **Settings** > **Diagnostics** > **Terminal API**. 2. Check if the **Status** is **Successful**.\ You can also **View results** and check if all items have a green check mark ![-white\_check\_mark-](/user/data/smileys/emoji/white_check_mark.png "-white_check_mark-"). 3. Select the **Cancel** button to go back to **Diagnostics**, and select **Endpoints**.\ The terminal runs tests on four URLs and then shows a final screen. 4. Check if the **Status** is **Successful** or select **View results** to check whether all four URLs in the final screen have a green check mark ![-white\_check\_mark-](/user/data/smileys/emoji/white_check_mark.png "-white_check_mark-"). ## Turn on/off If you turn on the payment terminal for the first time or after it was off for a long time, it may make a maintenance call to synchronize the configuration and update the software. This can take 10 to 20 minutes. #### Turn on the terminal: * Connect the terminal to a power supply.\ During startup the display turns on and off a few times. #### Reboot the terminal: 1. Go to **Settings** and select **Power**. 2. Enter your [passcode](/point-of-sale/menu-access?tab=manage_passcodes_in_the_customer_area_1#manage-passcodes). 3. Select **Restart** and confirm. #### Turn off the terminal: * Disconnect the terminal from the power supply. ## Payment terminal menus Your payment terminals have a menu with options related to payments, and a menu with options related to configuration. The access to some menu options is protected by passcodes. | Menu/Button | Description | Passcode | | ------------------------------------------------------------------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | ![](/user/pages/reuse/terminal-manuals/admin-menu-verifone/menu-settings.svg?decoding=auto\&fetchpriority=auto) **Settings** | * **Device info**: view information about the payment terminal, like the serial number, configuration version, and store details.
