SERIAL CONSOLE PORT MANAGER
3.3 System-Setup Ports
In order to ensure access to important command functions, Ports 1 and 2 are
designated as System-Setup Ports. System-Setup Ports always have access to
all
Serial
Console Port Manager commands.
Although any Serial Console Port Manager port can be granted access to all
commands, Ports 1 and 2 are the only ports that
always
have access to all command
functions, even when the Port Manager has been reset to the default state.
Supervisor Mode
cannot
be disabled at Ports 1 and 2.
Ports 1 and 2 provide a gateway through which the system administrator is
guaranteed access to all commands. Therefore, Ports 1 and 2 are always used for
communication during initial setup and configuration, or after the unit has been
re-initialized (reset) to default parameters.
NOTE
For more information on System-Setup Port capabilities, refer to
Section 5.2
.
3.4 Connecting Your PC to the Serial Console Port Manager
The Serial Console Port Manager can be controlled either (a) by a local PC that
communicates across a cable, or (b) through an external modem. For this
overview, assume we’re using a local PC running ProComm (or a similar
communications program) connected with a cable to Port 1; if you’ll be using a
modem link instead, see
Section 4.3
.
1. Attach a standard null-modem cable to your PC’s COM port. Make certain to
connect to the COM port used by your communications program.
2. Connect the other end of the cable to the Port Manager’s Port 1. For a
description of the port interface, please refer to the
Appendix
.
