TLA Startup Sequence
The following information is intended to provide troubleshooting hints in case
the logic analyzer fails to complete the startup sequence. You may want to refer
to Figure 6--30 on page 6--66 while reading the following paragraphs.
At power on, the mainframe software starts the mainframe and module kernel
tests. If the mainframe passes the kernel tests, it attempts to boot the Windows
operating system. If the mainframe fails the kernel tests, it displays the error
code(s), beeps, and terminates the startup sequence.
The Windows operating system starts the resource manager. The resource
manager performs the following tasks:
H
Mainframe power-on self tests.
H
Verifies the power-on self test status.
H
Inhibits any failed modules.
H
Records the power-on self test failures.
H
Determines the logic analyzer configuration.
H
Executes the system controller power-on diagnostics.
After completing all of the above tasks, the logic analyzer starts the Tektronix
Logic Analyzer application which performs the following tasks:
H
Power-on diagnostics on all installed modules.
H
Power-on diagnostics on the logic analyzer system.
H
Records the Pass/Fail status in the Calibration and Diagnostics property
sheet.
