Running Power-Up Self-Tests
The system automatically runs a power-up self-test when you
turn on the system power. The monitor and diagnostic LEDs
report any errors the power-up self-test detects. To find the
corrective action for any error codes the power-up self-test
reports, refer to Chapter 4.
You can specify a quick or a thorough power-up self-test script
to run when the system powers up.
The quick test script is a limited script that minimizes the
time until the system boots.
The thorough script runs an extensive check of system
hardware. The thorough power-up self-test script is most
useful for field service troubleshooting.
To select a power-up self-test script, use the setenv command
to set the testaction environment variable. Type setenv
testaction
(
q
|
t
) and press Return.
Specify q to select the quick test.
Specify t to select the thorough test.
