Starting and Testing
3.1 Turning On Your Workstation
• The system unit and the monitor run their power-up self-tests.
3.2 Using the Power-Up Self-Test
The power-up self-test verifies that the system is working correctly. It begins
automatically when you turn on your workstation. As the system performs
the test, you’ll see flickering text in the lower-left corner of the screen. This
flickering stops when the self-test is complete. If the test was successful, you’ll
see one of two console prompts on your screen:
•
>>
When this prompt is displayed, anyone can enter console commands.
•
R >
When this prompt appears, full console use is restricted to users who
know the password.
If you don’t know the password, you can use only two console commands: the
boot command (type boot and press Return) and the password command (type
passwd and press Return). If the software has been installed on your hard
disk or another storage drive, and if the boot path is correctly set the boot
command will start up the workstation software. (See Section 12.3.2.1.)
If your system fails to turn on, or if the self-test is unsuccessful, see Chapter 13
for instructions.
3.3 Using the System Self-Test
The system self-test, like the power-up self-test, checks to see that the system
is functioning correctly. It’s a more thorough test than the power-up self-test.
Caution
Before running the system self-test, make sure that your workstation
is either connected to a network or has a loopback connector in the
Ethernet connector on the back panel. Otherwise the test will fail.
See Chapter 5 of this guide for more information about Ethernet
connections.
Run the system self-test by following these steps:
1. Turn on your workstation and wait until the power-up self-test is complete.
2. When you see the console prompt (>>), type
test and press Return.
