Owner`s manual

Following power-up and system reset, the system performs testing and
displays the results on the console terminal. As testing begins, the red
Fault light on the control panel lights (see Section 3.5).
Most of the modules in the XMI card cage have on-board ROM used for
testing. The first indication that testing has begun on (Models 400 and
higher only) is the printing of a line of numbers, which is the first line of
the self-test display (see in Figure 6–1). This line, called the progress
trace, is generated by a processor module in slot 1 of the XMI card cage.

Each number displayed reflects the successful completion of tests run by
this processor. For Models 300 and 200 the start of self-test is indicated by
the NODE # line in the self-test display.
All modules have yellow LEDs on the outer edge of the module that light
when the module passes self-test. The LEDs on the modules can be viewed
from the front of the cabinet when the cabinet door is open. If a module
fails self-test, its yellow LED does not light.
This first round of testing completes, and the results are shown on the STF
line. The boot processor is then determined. This processor then generates
the results of testing to this point . The testing takes 10 to 15 seconds.
Next, the processors run additional tests using the memory modules. In this
extended testing the processor that had been designated as boot processor
could fail, so the boot processor is again determined. Results are displayed
on the ETF line .
The status of the boot processor and secondary processors is then displayed
on the second BPD line .
The boot processor next configures memory and displays the configuration.
At this point if any memory had a noncorrectable error, all memory
addresses for that module are tested, so there could be a delay before the
console prompt appears.
Note that it is the boot processor determined at that displays the lines
after the first BPD line. The final line before the prompt is from the boot
processor’s EEPROM.
Each line of the self-test display is described in detail in the following
sections of this chapter.

If your system has a T2019 power regulator in the XMI card cage, the progress trace line
is not displayed.
