Cannot Connect to UltraNEXUS-HD Series Server

If you cannot connect to your UltraNEXUS-HD and/or you get a "socket timeout" message, the following are some things to try. This covers the UltraNEXUS-HD, UltraNEXUS-HD Blade, UltraNEXUS-HD X2 and X5, UltraNEXUS-HD FLEX, and UltraNEXUS-HD CAST.

If you are trying to connect remotely, for example,  from your home computer, check with your IT department for help with the remote connection. If on the same network, try these steps:

Use Passive FTP

  1. To use passive FTP in the WinLGX software, open WinLGX but don’t connect. Close the Site Manager window.
  2. Go to the tools menu and select Preferences.
  3. Check the box that says Use Passive FTP in the Preferences window and click OK at the bottom.
  4. Close WinLGX, reopen, and connect.

Check the Site Manager IP Address

Make sure the IP address listed in the WinLGX Site Manager window matches the IP address in the UltraNEXUS-HD.

  1. Open the Site Manager window by going to the Tools menu and selecting Site Manager.
  2. In that window, it should list the IP address for the UltraNEXUS-HD.
  3. To check what IP address the UltraNEXUS-HD is set to, from the front panel, press the up arrow until the IP address is displayed.
  4. If the addresses do not match, click the ADD button in the bottom left corner of the Site Manager window to add the UltraNEXUS-HD IP address.

CONNECT Button Greyed Out

If the Site Manager window's Connect button is greyed out (inactive), select the IP address listed in the Site Manager window.

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
    1. Power the unit off using the power switch on the back.
    2. Reseat the SD card from the front panel.
      1. Gently press it in, and it should pop out.
      2. Gently press it back in until it clicks.
    3. Power the unit back on with the power switch on the back.
  • Check that the ethernet port on the front of the UltraNEXUS-HD lights up when an ethernet cable is plugged into the port.

    • If they do NOT light up, the UltraNEXUS-HD may need to be repaired or replaced.
    • If the lights DO light up, the SD card may need to be replaced.
    • Contact LEIGHTRONIX Support.

Reboot the UltraNEXUS-HD

  1. Reboot the UltraNEXUS-HD by pressing and holding the Green check button on the front of the UltraNEXUS-HD for seven seconds.
  2. This will initiate a warm reset reboot.
  3. When the date and time reappear on the front display, wait another two minutes and then try to connect.

Check Network Cable Connections

  • Confirm that an ethernet cable is connected to ethernet port one on the front of the UltraNEXUS-HD.
  • Make sure the lights on that port are lit up.
  • Make sure the ethernet cable is connected securely at both ends.
  • Try a different ethernet cable.
  • Try a different port on the router/switch.
  • Make sure the router/switch is working.
  • Also, make sure the lights on the network port where the cable plugs into the network router or switch are lit up. If they are not, please consult with your IT department.

Check for Network Changes

  • Check with your IT department to see if any changes have been made to your network, especially if you get a "socket timeout" message.
  • If changes have been made, your IT department may need to provide you with a new IP address, subnet mask, and gateway for the UltraNEXUS-HD.

Check for IP Address Conflict

  • Make sure no other device is using the same IP address as the UltraNEXUS-HD.
  • Check with your IT department.

Check for USB Hard Drive Issues

Try disconnecting any USB hard drive units from the back of the UltraNEXUS-HD.

  1. There are two USB ports on the back of the UltraNEXUS-HD. Remove all USB cables or devices from those ports.
  2. Reboot the UltraNEXUS-HD, leaving those ports empty.
  3. When the UltraNEXUS-HD is back up,  attempt to connect to the unit.

If a connection is successful without the USB hard drives attached to the UltraNEXUS-HD, there is a problem with the USB hard drives. They may require maintenance or may need to be replaced. 

Try a Direct Connection

Try connecting a PC or Windows Laptop directly to the UltraNEXUS-HD, bypassing any network.

  • Use a single ethernet cable between the PC and the UltraNEXUS-HD.
  • The PC/Laptop will need to be set to a static IP address within the range of the UltraNEXUS-HD IP address (ask your IT department for help with this).

If a direct connection works, then the UltraNEXUS-HD is working correctly, and there is an issue with your network setup, check with your IT department.

If a direct connection fails, the UltraNEXUS-HD may need to be repaired or replaced.
