Problems Getting to Console Mode
Problems Getting to Console Mode
This section describes how to troubleshoot the system when you
power up the system, but the console terminal does not display
the power-up screen.
Table 4–6 Troubleshooting Problems Getting to Console Mode
Symptom Action
Power-up screen is not
displayed. Check power-up/diagnostic display on the operator
control panel. (Table 4–7) for a failure during self-tests.
Check that keyboard and monitor are properly
connected and powered on (‘‘Terminal Connections’’
section in Chapter 1).
If the power-up screen is not displayed, yet the system
enters console mode when you press the Return key,
check that the
console
environment variable is set
correctly. If you are using a VGA console terminal, the
variable should be set to ‘‘graphics.’’ If you are using a
serial terminal, the variable should be set to ‘‘serial.’’
If
console
is set to ‘‘serial,’’ the power-up screen is
routed to the COM1 serial communicaton port ( set
console
command section in the AlphaServer 2000
/2100 Firmware Reference Guide) and cannot be viewed
from the VGA monitor.
Try connecting a console terminal to the COM1 serial
communication port (‘‘Terminal Connections’’ section in
Chapter 1). If necessary use a 9-pin connector. Check
baud rate setting for console terminal and system.
The system baud rate setting is 9600. When using the
COM1 port, set the
console
environment variable to
‘‘serial.’’
