Alternate Consoles
Description
The Model 90 provides two ways to use alternate consoles if the
graphics subsystem fails. Console commands can be entered
on a terminal connected to the printer/communications port,
communications/printer (RS232) port, or from either Ethernet
(standard, ThinWire) network port. The two alternate consoles
are described in the following sections.
Printer Port
Console
To access the printer/communications port, communications
/printer port console, verify that:
The baud rate of the terminal connected to the printer port is
set at 9600 baud.
The alternate console switch (S3) located on the front panel
is in the up position.
NOTE
The state of the alternate console switch is only read
at power up. Changing the switch setting when the
system is powering up has no effect until the system
box is powered down and then powered up again.
Network
Console
The system console can be accessed from the network. The
network console allows you to remotely troubleshoot the system or
provide a console when the other consoles are not available.
Some console tests and commands cause the network connection
to be terminated because the commands use the network device,
or they cause a connection timeout at the remote node.
To access the console you need:
The hardware Ethernet address of the VAXstation computer.
Access to a VMS operating system on the same Ethernet
segment as the VAXstation 4000 computer (the systems
cannot be separated by a bridge or router).
