Table 6–6: Failure symptoms and possible causes (cont.)
Symptom Possible cause(s)
Modules not recognized
H
Module firmware incompatible with mainframe software version.
Refer to the TLA 700 Series Installation Manual for software
and module firmware update instructions.
H
TLA 700 system problem. Execute the internal resource
manager program to determine if the mainframe recognizes
any installed modules. Refer to instructions on page 6–32.
H
Module may not be not fully inserted, make sure the front of the
module is flush with front panel. Power off the benchtop chassis
and reseat the module.

Eliminate Other Problem Sources
This module is part of the TLA 700 Series Logic Analyzer, which comprises
modules and the benchtop chassis (and in this case, the benchtop controller). The
following procedures will help you eliminate the benchtop chassis and other
modules as possible sources of the failure(s) before you troubleshoot the
benchtop controller.
If you have available a known-good controller, perform the following procedure:
1. Remove the suspect benchtop controller from the benchtop chassis. The
benchtop controller is a VXIbus slot zero form factor device. First verify that
the benchtop controller is installed in slot zero and one (the benchtop
controller is a dual-wide module).
2. Install the known-good benchtop controller in slot zero.
3. Power-on the benchtop chassis and check for normal operation.
4. If the failure symptoms are still present with the known-good benchtop
controller installed, the problem is most likely in the benchtop chassis, not in
the benchtop controller. Refer to the Troubleshooting section in Chapter 6 of
your Benchtop Chassis Service Manual.
5. If your benchtop chassis operates normally with the known-good benchtop
controller installed, then the suspect benchtop controller needs to be serviced.
Refer to the Troubleshoot the Benchtop Controller Module on
page 6–27.
