7.6 Hardware trouble shooting
7.6.1 Internal and external LANs
7.6.1.1 No Ethernet connection between the unit
and the workstation
• See if the problem can be resolved by restarting
the X-ray unit and the workstation.
• Check for problems in the workstation.
• Check for problems in network cables.
Try to set up a connection between the X-ray unit
and the workstation using the s2terminal.
If a connection is established, check the
installation and configuration of the image
acquisition driver software.
Try to set up a connection between the X-ray unit
and another PC (for example service
laptop) using the s2terminal. If a connection can
be established the problem is with the
workstation.
Check that the “link” light, normally located next
to the workstation’s network connector, is on
when the cable is attached. If it is not on, the
network card may be faulty. Check if the light is
on when the service laptop is connected, this
confirms whether the network card is faulty or
not.
Replace the network cable between the X-ray
unit and the workstation with an Ethernet cable
(CAT5e or CAT6) known to be working.
If a connection is established, replace the original
cable.
Connect the known to be working Ethernet cable
between the workstation and connector JB004 in
the upper part of the column. If a connection is
established, replace the energy chain cables lo-
cated behind the column.
Connect the known to be working Ethernet cable
between the workstation and connector J3220
on the R3220 Main CPU board. If a connection is
established, replace the whole main cabling in
the rotating unit.
