      UltraNEXUS-HD Won't Boot up, Power on, or the Front Display is Frozen

      Here are some items to check. This covers the UltraNEXUS-HD, UltraNEXUS-HD Blade, UltraNEXUS-HD X2 and X5, UltraNEXUS-HD FLEX, and UltraNEXUS-HD CAST.

      UltraNEXUS-HD Powered On

      Make sure the unit is powered on and running.
      • Check that the front panel display has the date and time and that the time is ticking and not frozen.
        • If the display is frozen, try turning the power off using the switch on the back of the unit, then power it back on.
      • If there is no display, make sure the power source is working and the power cord is good.
        • Verify that the power cord is connected securely to the back of the unit.

      Front Display Stays on Start-Up Message

      If the front display is stuck on the start-up message ("LEIGHTRONIX, INC") for more than 5 minutes, try the following:
      • Try reseating the SD card
        • Power the unit off using the power switch on the back.
        • Reseat the SD card from the front panel.
          • Gently press it in, and it should pop out.
          • Gently press it back in until it clicks.
        • Power the unit back on with the power switch on the back.
      • Confirm that the ethernet ports on the front of the UltraNEXUS-HD light up when an ethernet cable is plugged into the port.
        • The UltraNEXUS-HD may need to be repaired or replaced if they do not light up.
        • If the lights DO light up, the SD card may need to be replaced.
