Console language
Used by the system operator at the console terminal to communicate with
the primary processor; provides the interface to diagnostics. The console
language uses options, environment variables, and arguments.
Options modify the action of the command in some way, or give details of
how the command is to operate; they appear in the form -xxx and are pre-
ceded by a space.
Environment variables determine the environment; some are set in manu-
facturing and set up a default environment. Most environment variables
are defined with the set command. See also Environment variables.
Console mode
A mode of operation where the processor is not running the operating sys-
tem but allows a console terminal operator to communicate with nodes on
the LSB bus and I/O bus adapters and devices.
Console program
The code that the boot processor executes during console mode. Each proc-
essor has a copy of this code in flash ROMs. After a boot processor has
been determined, that processor begins console initialization. The console
code is then loaded into memory.
Control panel
Consists of a keyswitch to control the state of the system and three status
LEDs.
CPU module
The KN7AA processor is the CPU module used in DEC 7000 systems. The
KA7AA processor is the CPU module used in VAX 7000 systems.
Device
From the console perspective, "device" can be used to refer to a physical de-
vice, a block of memory, or a set of registers. The console commands oper-
ate on byte streams, so any of these can be expressed as a byte stream.
Each physical device in a system has a unique mnemonic assigned by the
console program, which is displayed as part of the show configuration,
show device, and show network commands.
DEMFA
XMI adapter to the FDDI (Fiber Distributed Data Interface).
