      Cannot Connect to NEXUS/UltraNEXUS?

      If you are unable to connect to your NEXUS/UltraNEXUS and/or you get a "socket timeout" message, here are some things to try.

      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. In the Preferences window, check the box that says Use Passive FTP, 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 NEXUS/UltraNEXUS.

      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 NEXUS/UltraNEXUS.
      3. To see what IP address the NEXUS/UltraNEXUS is set to, from it's 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 NEXUS/UltraNEXUS 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.

      NEXUS/UltraNEXUS Powered On

      Make sure the unit is powered on and running.

      • Check that the front panel display has the date and time and the time is ticking and not frozen. 
      • If display is frozen try unplugging the unit from power and then plug it back in and power it up.
      • If no display at all, make sure power source is working and the power cord is good. Make sure the power cord is connected securely to the back of the unit.

      Reboot the NEXUS/UltraNEXUS

      1. Reboot the NEXUS/UltraNEXUS by pressing and holding the UP and DOWN arrow buttons on the front of the NEXUS/UltraNEXUS at the same time for two 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 1 on the back of the NEXUS/UltraNEXUS.
      • Make sure the lights on that port are lit up.
      • Make sure the ethernet cable is connected 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 NEXUS/UltraNEXUS.

      Check for IP Address Conflict

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

      Check for USB Hard Drive Issues

      Try disconnecting any USB hard drive units from the back of the NEXUS/UltraNEXUS.

      1. There are four USB ports on the back of the NEXUS/UltraNEXUS. Remove any USB cables or devices from those ports.
      2. Reboot the NEXUS/UltraNEXUS, leaving those ports empty.
      3. When the NEXUS/UltraNEXUS is back up, connect to the unit.

      If a connection is successful without the USB hard drives attached to the NEXUS/UltraNEXUS, there is a problem with the USB hard drives. They may require maintenance or may need to be replaced. Search the knowledge base for "hard drive maintenance".

      Try a Direct Connection

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

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

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

      If a direct connection fails, the NEXUS/UltraNEXUS may need to be replaced.
