1.1.1 Power-Up Test Codes

The power-up test codes indicate no error, soft errors, status information,

or hard (fatal) error information. Any errors found by power-up tests are

listed in the power-up tests summary. These errors, as well as the status

of all devices installed in the system, are then stored in the conﬁguration

table (T 50). Refer to Example 1–3 for an example of the conﬁguration

table.

Table 1–1 lists the test numbers and the devices that are tested during

that particular test. To look at the status of a device, display the

conﬁguration table.

>>> TEST 50

The conﬁguration table lists every device in the system and also lists

the results of the power-up tests and self-test. The conﬁguration table

is updated each time a self-test is run (mouse status is not updated).

Remember that the conﬁguration table contains the results of the power-

up tests and self-test, and not the results of the system exerciser.
