11. When power is applied, the LC board will perform a set of self-test diagnostics.
Figure 3-2 illustrates the diagnostic LEDs on the LC Electronics module. Refer
to
Table 2-9 for LED descriptions.
12. Observe the following LED indications:
— Each of the set of eight LEDs (1 - 8) will be individually lit and then turned
off in sequence starting with LED 1. When this test is completed, all LEDs
(except P and C) should be off.
— The 640 Kbytes of user RAM will be tested. The amount tested will be
displayed on the external personal computer. If the test encounters an error,
LED 1 will be lit and an error message will be written to the external
personal computer.
— The LC will now enter its bootstrap routine. If the LC is configured to boot
from the externaldisk, and it cannot communicate with the externalpersonal
computer, LED2 will be lit. If this occurs, check the cabling.
If no errors occur, when the LC has completed its start-up routine, only LEDs P
(Power OK) and C (Communication OK) will be lit.
13. After the LC card has been booted from the external PC, format Drive B as a
system disk by entering the following command:
