Isolating System Problems
If you have completed all of the troubleshooting procedures up to this point and
the TLA application fails to display any modules in the System Window, you
may have a system problem. Check for the following:
H
Verify that all modules are properly installed.
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.
You can execute the internal resource manager program (ResMan32.exe) to
identify if any of the installed modules are being identified in the mainframe
slots. Table 4–6 lists some of the command line options for executing Res-
Man32.
