This indicates the line is not sending data.  When you perform a dot test and you notice that several lines are down, you'll need to check the turbine collectors inside the unit to ensure they are properly connected and not compromised.  ![v4 all line down](https://support.beerboard.com/hs-fs/hubfs/Training%20Department/Stills/BevBox/v4/v4%20all%20line%20down.jpg?width=688&height=387&name=v4%20all%20line%20down.jpg) To do this, use a small Phillips screwdriver and unscrew the four screws around the turbine collector (shown below). The wires near the ethernet port (red and black) must all be securely attached. If they are not, secure them and check the dots for connection confirmation. ![MicrosoftTeams-image (14)](https://support.beerboard.com/hs-fs/hubfs/Training%20Department/Stills/BevBox/v4/MicrosoftTeams-image%20(14).png?width=688&height=361&name=MicrosoftTeams-image%20(14).png) ![MicrosoftTeams-image (15)](https://support.beerboard.com/hs-fs/hubfs/Training%20Department/Stills/BevBox/v4/MicrosoftTeams-image%20(15).png?width=688&height=466&name=MicrosoftTeams-image%20(15).png) > There is a small led light that blinks indicating connection between the BevBox and turbine collector but that does not necessarily mean there is a *good* connection. ![MicrosoftTeams-image (13)](https://support.beerboard.com/hs-fs/hubfs/Training%20Department/Stills/BevBox/v4/MicrosoftTeams-image%20(13).png?width=688&height=654&name=MicrosoftTeams-image%20(13).png) If they are secure and the LED light indicates a connection between the BevBox and turbine collector, but the dots are still down, [contact support](https://share.hsforms.com/1b6jKgzmvTI-oms75xoTasw3vlv9).      - [Bars and Restaurants](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#main-content) - [SmartBar](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#smartbar) - [Product Management](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#product-management) - [Yield Management](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#yield-management) - [BeerBoard TV](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#beerboard-tv) - [SmartBar Mobile App](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#smartbar-mobile-app) - [BeerBoard P@Y](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#beerboard-py) - [SmartMenus](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#smartmenus) - [SmartOrders](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#smartorders) - [Integrations Setup](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#integrations-setup) - [New SmartBar](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#new-smartbar) - [BevBox](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#bevbox) - [Beer Tour](https://support.beerboard.com/knowledge/bars-and-restaurants?hsLang=en#beer-tour) - [General FAQs](https://support.beerboard.com/knowledge/general-faqs?hsLang=en#main-content) - [SmartBar](https://support.beerboard.com/knowledge/general-faqs?hsLang=en#smartbar) - [SmartOrders](https://support.beerboard.com/knowledge/general-faqs?hsLang=en#smartorders) - [Claim Your Brand](https://support.beerboard.com/knowledge/claim-your-brand?hsLang=en#main-content) - [Distributors, Wholesalers, and Suppliers](https://support.beerboard.com/knowledge/claim-your-brand?hsLang=en#distributors-wholesalers-and-suppliers) - [Claim Your Brand FAQs](https://support.beerboard.com/knowledge/claim-your-brand?hsLang=en#claim-your-brand-faqs) - [Suppliers, Distributors, and Wholesalers](https://support.beerboard.com/knowledge/suppliers-distributors-and-wholesalers?hsLang=en#main-content) - [SmartOrders](https://support.beerboard.com/knowledge/suppliers-distributors-and-wholesalers?hsLang=en#smartorders) - [Insights](https://support.beerboard.com/knowledge/suppliers-distributors-and-wholesalers?hsLang=en#insights) - [General FAQ](https://support.beerboard.com/knowledge/suppliers-distributors-and-wholesalers?hsLang=en#general-faq) - [BeerBoard P@Y](https://support.beerboard.com/knowledge/suppliers-distributors-and-wholesalers?hsLang=en#beerboard-py) [![Chill listening crop-3](https://support.beerboard.com/hs-fs/hubfs/BeerBoard%20Logo-2.png?width=111&height=44&name=BeerBoard%20Logo-2.png "Chill listening crop-3")](https://www.beerboard.com/) 225 W Jefferson St, Syracuse, NY 13202 Copyright © 2025, BeerBoard
