.. index:: single: Troubleshooting Troubleshooting ===================== Before you go to field or in case of problems, you should check the system in detail. .. index:: single: Troubleshooting; System Check ADU-08e ---------- **Please download the instructions and the pdf from this folder** `JobLists `_ |br| **Execute the joblist and compare with the graphs inside the pdf.** Short Circuit In Cable ------------------------ If the cable (E or H, in this example E) has a short circuit the ADU. The short circuit will cause the ADU switch the power in the cable on and on again (with 30Hz) as you can see. .. image:: /media/troubleshooting/short_circuit_in_e_cable.png :width: 80% :align: center GPS ----- GPS board failure ^^^^^^^^^^^^^^^^^^^^^ When the GPS board fails the **front panel of the ADU-08e does not work**. |br| The operating system may work and the system may start and you hear the relais switching. You may login via ssh. In case that the GPS board is broken, following will appear: the boards will boot independently - and you hear the relays switching. |br| You can connect to the samba server: .. image:: /media/troubleshooting/GPS/Samba.png :width: 50% :align: center If **NOT** press new session in the web interface (but "call target") you see "ADU-0", 0V for battery, date 1970-01-01 and no satellites: .. image:: /media/troubleshooting/GPS/Web_CallTarget.png :width: 50% :align: center If press "new session" the web interface is dead: .. image:: /media/troubleshooting/GPS/Web_NewSession.png :width: 50% :align: center The GPS board must be replaced. Database failure ------------------ A database failure can be forced by unexpected shut off (pull battery cable) or a corrupted SSD card. |br| The **front panel will work**. But the web interface shows no data like above (ADU serial 0, = V, no satellites). In the field: ^^^^^^^^^^^^^^^^ * login via ssh * go to .... * Re-install database *“mysql -u root -p mcpdb < ./mcpdbRepair.sql”* ; password is !dgrtv255 * optional download from here :download:`mcpdbRepair.zip `, unzip and copy to /mtdata/data (that you do with your file explorer in case); *cd /mtdata/data* ; and do the step above * Reboot adu *“/home/Scripts/rebootSystem.sh”* **HENCE** that if the reason was a SSD starting to die, you will loose your data quite soon and all was for nothing. In the lab: ^^^^^^^^^^^^^^^ Exchange the system SSD card. :ref:`Open the Box `. to continue. |br| Exchange the system card; make sure thatthe card will not move out later (tape it, fix it). |br| Run the system update to ensure to have the latest version. .. _connecting_to_adu_troubleshooting: Connecting to ADU ---------------------- General ^^^^^^^^^^^^ Also the https of the ADU has a self-signed certificate. You must accept that (add an exception). |br| The network address is always in the range 192.168.xxx.yyy which is a private (non Internet) address. WiFi ^^^^^ The WiFi of the ADU is configured as *access point*. Attention: some phones or tablets want to switch back to another access point because the "don't see" the Internet behind the ADU. Cable ^^^^^^^^^ **If the ADU has 192.168.0.230 NEVER set your laptop to the same address! Take 192.168.0.10 for example** Linux ^^^^^^^ Linux user can add a second network. They can work in a DHCP in case your supervisor gives you always the same DHCP *and* static network at the same time. .. image:: /media/troubleshooting/linux_multi_network.png :width: 50% :align: center .. index:: single: IP Address; Windows Windows ^^^^^^^^^ In order to connect the ADU by cable network it is required to set the network setting in your Windows computer accordingly. In order to achieve this click on Windows settings. You will see this screen: |br| .. image:: /media/troubleshooting/windows_cable_con/1_windows_settings.png :width: 50% :align: center Click on Network and Internet and you will see this: .. image:: /media/troubleshooting/windows_cable_con/2_network_status.png :width: 50% :align: center Now click on Change adapter options and you will see a screen similar to this: .. image:: /media/troubleshooting/windows_cable_con/3_network_connections.png :width: 50% :align: center Now right-click on the Ethernet adapter you use. A screen like this will open: .. image:: /media/troubleshooting/windows_cable_con/4_network_ethernet.png :width: 50% :align: center Click on Properties and a screen like this will be shown: .. image:: /media/troubleshooting/windows_cable_con/5_ethernet_properties.png :width: 25% :align: center Now you need to double-click on Internet protocol Version 4 (TCP/IPv4). A screen like this will be shown: .. image:: /media/troubleshooting/windows_cable_con/6_tcp_ip_v4.png :width: 25% :align: center What has to be done now is to enter the address range which is used by the ADU. .. image:: /media/troubleshooting/windows_cable_con/7_tcp_ip_v4_properties.png :width: 25% :align: center You also enter a sub-net mask which is always 255.255.255.0 - which normally is filled in automatically. Strange behaviour on laptops in domains: .. image:: /media/troubleshooting/windows_cable_con/blocked_domain_mount.jpg :width: 25% :align: center 1.) login as local administrator (not any domain network) |br| 2.) log in to adu via web interface |br| 3.) afterwards it works even with a domian account. |br| This mostly the domain blocking for mounting devices seems to unlocked. .. index:: single: WiFi For WiFi the access is more easy. Confirm that you don't want to switch back, in case Windows can't see the Internet and suggests to sear for another access point. *Strange* things will happen in LAN when you manually configure IP addresses which are already in use. It may be that you reach the system or ing the system - but the network drives can not ne mounted. .. raw:: html

In worst case the system motherboard we be destroyed. Therefore a replacement will be done by us. The repair and shipping back to you will be free of charge - shipping to us us has to be born by the user. In case you have a skilled electronics engineer you may try yourself. It take 6 minutes. We send a package containing - a - a - a to you. Play the video or download :download:`voltage_regulator_replacement.mp4 ` and decide. |br| For making the video we removed the aluminum casing containing the ADB boards for better visibility; you need to do that. After finishing check the **orientation** of .... otherwise the ADU dies immediately. .. image:: /media/troubleshooting/vr/orientation.jpg :width: 50% :align: center
