Console
Subsystem On AlphaServer systems, underlying control of the system
platform hardware is provided by a console subsystem. The
console subsystem contains firmware code (software code
embedded in the hardware) that offers service functions such
as initializing and testing the hardware and bootstrapping
the system software. Because the AlphaServer 2000 supports
multiple operating systems, the server has two different
versions of console firmware. They are explained in detail in the
AlphaServer 2000/2100 Firmware Reference Guide.
Console
Terminal A console terminal is required for your system. You can
connect either a VGA monitor or a Digital VT-series terminal or
equivalent. The console terminal is used to configure the system
and boot the operating system. From the console terminal, you
can issue commands to the system while the operating system is
not running.
Console Mode
Console mode is the state in which the system and the console
terminal operate under the control of the console firmware rather
than the operating system. When you issue commands from the
console terminal and firmware is executing, you are in console
mode.
On DEC OSF/1 and OpenVMS systems, the console mode prompt
is
P00>>> . You can use control characters and supported keys to
enter console commands at the console mode prompt.
On Microsoft Windows NT systems, a menu interface is used in
console mode.
Invoking
Console Mode Invoke console mode by shutting down the operating system
according to the operating system shutdown procedure described
in your operating system documentation.
Pressing the Halt button on the operator control panel invokes
console mode if you are running DEC OSF/1 or OpenVMS.
However, invoke console mode with the Halt button only if you
are unable to shut down the DEC OSF/1 or OpenVMS operating
system using the proper software shutdown procedure. Pressing
