Turning the System On
Checking the
Power-Up
Displays
After you power up the system, check the status of three
diagnostic indicators: the power-up/diagnostic display on the
operator control panel, the system startup screen display, and
the console prompt (DEC OSF/1 or OpenVMS systems) or Boot
menu (Microsoft Windows NT systems).
If any of the diagnostic indicators do not appear as described,
refer to Chapter 4 for help.
Operator Control Panel Power-Up/Diagnostic Display
The power-up/diagnostic display located on the operator control
panel on the front of the system displays the results of system
self-tests during power-up.
As self-tests begin, the power-up/diagnostic display shows the
following message for several seconds:
starting console
When the system has completed self-tests, the message
Model
x/xxx is displayed, where x represents the CPU variant and xxx
represents the system model number—for example, Model 4/200 .
You can customize this message for your system by changing the
value of the ocp_text environment variable. Refer to the section
on the
set ocp_text command in the AlphaServer 2000/2100
Firmware Reference Guide.
Table 4–7 describes how to interpret messages on the power-up
display.
Note
AlphaServer 2000 systems offer high-availability ‘‘CPU
failover’’ functionality. On multiprocessor systems, the
failover feature allows the system to power up and boot
the operating system even if one CPU has failed. The
CPU STATUS message described in Table 4–7 indicates
the status of each CPU. For more information on CPU
failover, see Chapter 4.
