As a first step, locate the appliance in the store. RetaiNext store appliances generally have a RetailNext logo on the outside, which helps in quickly identifying them among other IT equipment in the store. If there isn't a logo, look for the machine in the store that has the HP logo and looks simliar to the below. The device will be located near your ISP router and near other "Tech Area Devices"
Ensure that the store appliance is powered on by confirming that the power LED is illuminated. If it isn't, try pressing the power button to turn on the appliance. If that doesn't work, check the power supply to the appliance.
Note that if the LED is blinking red and/or white, usually along with audible beeps, there is a hardware issue with the appliance and it will need to be repaired or replaced.
Ensure that the appliance has an ethernet cable connected to it and that the other side of the cable is connected properly to the switch Ensure that the LEDs next to the ethernet port on the appliance as well as the switch or router are active. If the LEDs aren't active, try replacing the ethernet cable.
