TLA721 Benchtop & TLA7XM Expansion Mainframe Service Manual
Table 6- 9: Failure symptoms and possible causes (Cont.)
Symptom
Possible causes and recommended action
Portable Mainframe will not power-
off with On/Standby switch.
The mainframe utilities may be set up to disable hard power-off. Check the setting of the
mainframe utilities (the mainframe utilities are located in the Windows Control Panel).
This is a Windows operating system problem. Try powering-off the mainframe using the
Windows shutdown procedure. If the mainframe still does not power-off, disconnect power cord
and reconnect after 10 seconds to reboot the mainframe.
Expansion Mainframe will not
power-off with On/Standby switch.
If the expansion mainframe was incorrectly shut down (for example, the power cord was
disconnected while the expansion mainframe was running) the expansion mainframe utility still
“thinks” that the expansion mainframe is on.
To correct this condition, press and hold the power switch for three to four seconds. The
expansion mainframe will power-down on its own. Power-off the benchtop mainframe. Power-on
the benchtop mainframe, the expansion mainframe will power-up normally.
Isolating System Problems
If you have looked at Table 6--9 and the Tektronix Logic Analyzer application
fails to display any modules in the System window, you may have a system
problem. Check for the following:
H
Verify that the module address switches are set correctly. Power off the
mainframe and remove the modules. Set the address switches to FF and
reinstall the modules.
H
Verify that the modules do not have the flash programming jumper installed
on the rear of the module. Power off the mainframe and remove the modules.
Remove the jumper and reinstall the modules.
H
Try placing a suspected module in a different slot to verify slot dependency
problems. For example, if you have a single module in slots 2 and 3, power
off the mainframe, move the module to slots 3 and 4, and try the tests again
If the module works in the new location, you have identified a faulty slot in
the mainframe.
H
Check for bent or broken pins on the backplane of the mainframe.
H
Faulty module. Replace the suspected faulty module with a known good
module, or contact your local Tektronix service center.
H
Incompatible module firmware and mainframe software versions. You may
have to update the system software and the module firmware so that they are
compatible Refer to the
Tektronix Logic Analyzer Family User Manual
for
updating the system software and module firmware.
H
Check for computer viruses.
