Running the Console Program: Invoking Console Mode
From the
Auxiliary Serial
Port One way to access your system from a remote site is through
a device at the remote site that is connected to your system’s
auxiliary serial port on the I/O module at the rear of the system.
When your system is running in operating system mode, you can
access console mode from this remote access device as follows:
1. Set host to your system from the remote access device.
2. Shut down the operating system or:
If the tta1_halts environment variable on your system is set
to 2, press Ctrl/P on the remote access device keyboard.
For information about setting the tta1_halts environment
variable, refer to Enabling Halt Key Functions (tta0_halts and
tta1_halts) in Chapter 4.
From Across
the Ethernet Another way to access your system from a remote site is through
the Ethernet. You can connect to your DEC 4000 AXP system
from any device that is on the same Ethernet segment, or local
area network.
Accessing your system from across the Ethernet differs
depending on whether your system is in console or operating
system mode.
In Operating System Mode
If your system is in operating system mode, access console mode
from this remote device as follows:
1. Set host to your system using the protocol appropriate to
your network device, possibly DECnet or MOP. Refer to your
operating system documentation for information about the
appropriate protocol for your system.
2. Shut down the operating system. Refer to your operating
system documentation for instructions.
As the operating system shuts down, you will lose the
connection to your system.
3. Under the OpenVMS AXP operating system, reconnect to
your system using the instructions that follow.
