6.4 Troubleshooting
6.4.1 System Engineer Installation or running problems
1.
Verify that Microsoft .NET Framework version 3.5 or 4.0 is
correctly installed.
Warning
: the complete .NET Framework is
necessary (don’t install only "profile client" or "SDK" versions).
2.
Verify if Microsoft .NET Framework version 1.1 or 2.0 are not
installed on your computer. If it is the case, it is advised to
uninstall with Microsoft .NET Framework removal tool, and
then to reinstall .NET Framework 3.5 or 4.0.
Warning
:
uninstalling these former versions can prevent some of your
software to work correctly, if they use it.
3.
Before installing a new System Engineer version, it is strongly
advised to uninstall all previous versions.
4.
Try to uninstall and reinstall System Engineer.
6.4.2 Connection problems
If System Engineer cannot connect to the device:
•
Verify that the RJ45 cable is plugged, that all the devices are powered on, and that the
RJ45 ports LEDs (yellow and green) are blinking.
Solution
Verify all cables, RJ45 can be rather fragile.
•
Check that the Firewall in the computer will allow System Engineer access to the
network.
•
Wait 10 minutes (for the computer to acquire the correct IP address) and try again.
•
Check that the Current IP address in the device is compatible with the IP address of the
computer. Generally, the leftmost two sets of 3 digits should be the same.
•
Always switch on any DHCP server before connecting either the computer or amplifier
to the network.
•
Verify that your System Engineer version is recent enough to use the T-44 (V6.16 or
more).
Solution
Install the latest System Engineer version
•
Verify that "Ethernet" network appears in the System Engineer left panel, in Network
view.
Solution
"Network"→
"Add Ne
tworks"→select "Ethernet"→
"Add"
•
Do not forget to click on the co
nnection button or on "Network"→
"Connexion"
•
If the T-44/48 is directly plugged to the computer RJ45 port, and everything is in
automatic mode, wait 2 minutes before trying to connect again. (Windows has to stop
looking for a DHCP server, and then the T-44/48 has to choose an address. The
Online
LED has to stop blinking)
