Testing System Components
Testing a Single
Component
To test a particular device or component in your system, follow
these steps:
1.
Use Table 5–2 to find the number or mnemonic for the device
or component you want to test.
2.
Before halting or turning off your system, see the operating
system documentation for shutdown procedures. If your
system is part of a networked work group, do not turn off,
halt, or restart the system without notifying work group
members.
3.
Put the system in console mode (>>>) by pressing the halt
button behind the door on the front of the system unit.
4.
Enter TEST followed by a space and either the number or
mnemonic of the device or component to be tested; then press
the Return key.
Example
For example, to test nonvolatile random access memory (RAM),
enter:
>>> TEST NVR
Return
or
>>> TEST 1
Return
At first, the system displays an unfilled status bar. As the test
runs, the status bar fills. When the test is successful, the status
bar fills completely and the console prompt displays.
