Console Terminals; Serial Port Connectors; Network Connection - HPE AlphaServer 300 User Manual

Console Terminals

The AlphaServer 300 system supports two types of console terminals, a graphics terminal
and a serial terminal. 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 when
the operating system is not running. If you are using the Windows NT operating system, a
graphics terminal is required. If you are using either OpenVMS or Digital UNIX, the
terminal may be graphics or serial.
•
The graphics terminal attaches to the graphics adapter card on the back of the system.
(This terminal is shown on the right side of Figure 2-4.) The "console" environment
variable should be set to "graphics."
•
The serial terminal attaches to the COM1 port on the back of the system. (This
terminal is shown at the bottom of Figure 2-4.) The "console" environment variable
should be set to "serial."
See Chapter 3, Console Commands, for more information on environment
variables.

Serial Port Connectors

The serial port connectors consist of two 9-pin D-subminiature connectors.
The baud rates supported by the system's serial ports are 50, 75, 110, 134.5, 150, 300, 600,
1200, 1800, 2000, 2400, 3600, 4800, 7200, 9600, 19200, 38400, and 57600 (56000 with
approximately 3% error), and 115200.
Refer to your operating system documentation to confirm which baud rates
are supported by your operating system.

Network Connection

Connect your network interface cable to the appropriate port on your network module. If
you are using the Digital UNIX or OpenVMS operating systems, the ThinWire port is
selected by default. You can change to the twisted-pair port by entering the following
SRM console command:
>>>set ewa0_mode twisted (See Chapter 3, Console Commands.)
