• Check the internet connection to ensure it it functioning.
  • If attempting to access a specific website via the Internet, check to see if another website can be accessed through the internet browser.
  • If attempting to PING another IP address on the network, check to see whether that IP address can be accessed from another client.
  • Check the switch or router to ensure it is working - check the network ports to ensure they are working.
  • If network access is controlled by a central MAC address database, ensure that the correct MAC address of the device in question is included in the database.
  • If there has been a recent power outage, check whether devices (servers, switches, routers etc) have been probably reset or turned on.

Hard wired Ethernet connections:

  • If using Static IP:  ensure that there are no duplicate IPs on the network.
  • If using DHCP:  check the network port by connecting a portable notebook computer at the same network jack, or;
  • Check the system at another station to ensure it is not a network port problem.
  • Check the CAT5e / CAT6 network cable.
  • If using PoE:
    • Make sure the network cables are firmly connected from the PoE switch to the internal PoE splitter and/or PoE injector.
    • Make sure the network patch cable is firmly connected on the computer from the POE Out port of the internal PoE splitter to the LAN port of the motherboard.
    • Check that overall power capacity of the PoE switch has not been met.
    • If using a POE switch, confirm that the port is properly configured to deliver sufficient power to the system.
    • If using a POE injector, confirm all cables are properly connected, and that the injector can deliver sufficient power to the system.

Wireless connections:

  • Check to see if external wireless antenna is connected and threaded properly into the connector.
  • Try swapping an antenna from a working device.
  • Check that the wireless access point is online and accessible through other wireless clients.
  • Ensure that the correct SSID / Passphrase is entered in the wireless settings on the thin client.
  • If using a Windows 7 device:
    • Verify or update wireless configuration on the client
    • Commit changes to the system using XPe's Enhanced Write Filter Manager (EWF) and reboot the system.


Models affected: TL7200, TL7400, TL7600, TL8400

The touch screen is either damaged, or the internal hardware is likely defective.

To run an initial check to your integrated touch thin client of whether the repair may be an in-warranty or out-of-warranty repair, check for cuts, faded areas or cracks across the screen, or damage to the system's plastic housing.  Any physical damage voids the system warranty.


There are several possible issues that can be checked:

  • Is internet service working (check with your internet provider)?
  • Is the wireless router working (powered on, ports working)?
  • Is the system within a reasonable distance of the wireless router?
  • Is software configured correctly? (network settings in OS, sw, drivers, router, wireless band [a/b/g/n/ac], passphrase)?
  • Is the wireless card properly connected and working?
  • Is your antenna properly connected (internal or external)?
  • Is the motherboard working properly?


  • Thinlabs PoE Computers can be powered by a POE 802.3at+ switch or midspan power injector.
  • A POE 802.3AT+ switch / injector can supply 30W or higher power per port.  
  • The device can be powered up to 100 meters (330 feet) using a CAT5e / CAT6 Ethernet cable.
  • Switches must be properly configured to provide the necessary power to a port. 
  • Check the peak capacity for an entire switch, which may be less than if all channels are plugged in.  


Configure your Cisco switch so that it properly works with Thinlabs Power over Ethernet (PoE) Computers (including, but not limited to,TL2530P, TL2640P, TL7600P, TL8510P, TL8610P models)..

Detailed Instructions

      Command or Action Purpose
    1 enable 

    Switch> enable

    Enables privileged EXEC mode - enter your password if prompted.


    2 configure terminal 

    Switch# configure terminal 

    Enters global configuration mode.

    3 interface interface-id 

    Switch(config)# interface gigabitethernet2/0/1 

    Specifies the physical port to be configured, and enters interface configuration mode.

    4 power inline {auto [max max-wattage] | never |static [max max-wattage]} 

    Switch(config-if)# power inline auto 

    Configures the PoE mode on the port.  Keywords and meanings:


      auto - Enables powered-device detection; if enough power is available, automatically allocates power to the PoE port after device detection (default setting).


      max max-wattage - limits the power allowed on the port; if no value is specified, the maximum is allowed.


      max max-wattage - limits the power allowed on the port; range is 4000 to 30000 mW; if no value is specified, the maximum is allowed.


      never - disables device detection, and disable power to the port.


    If a port has a Cisco powered device connected to it, do not use the power inline never command to configure the port. A false link-up can occur, placing the port into the error-disabled state.


      static - Enables powered-device detection; pre-allocate (reserve) power for a port before the switch discovers the powered device; the switch reserves power for this port even when no device is connected and guarantees that power will be provided upon device detection.

    The switch allocates power to a port configured in static mode before it allocates power to a port configured in auto mode.

    5 end 

    Switch(config-if)# end

    Returns to privileged EXEC mode.

    6 show power inline [interface-id | module switch-number] 

    Switch# show power inline 

    Displays PoE status for a switch or a switch stack, for the specified interface, or for a specified stack member.

    The module switch-number keywords are supported only on stacking-capable switches.

    7 copy running-config startup-config 

    Switch# copy running-config startup-config

    (Optional) saves your entries in the configuration file.
