Date Code 20120126 Instruction Manual SEL-2032 Communications Processor
Section 3
Job Done Examples
Introduction
This section describes SEL-2032 Communications Processor operations and
user interface with examples that include a variety of common applications.
Each example assumes you have successfully performed Getting Started on
page 2.15, and that you have configured the SEL-2032 hardware by placing
jumpers according to the instructions in Jumper Settings on page 2.1. The
examples include an introduction to the problem or task, identification of the
problem, overview or definition of the solution, and the step-by-step
procedure you should follow to accomplish the solution with the SEL-2032.

examples are also available for plug-in protocol card applications.
See the instruction manual of each protocol card for examples of using the
card-specific protocols and operations.
Example 1: Connect to the Front Port and Change
Default Passwords
Introduction
This example demonstrates how to connect your PC or terminal to the front
port (Port F), establish serial I/O communications, and change the factory-
default password settings on the SEL-2032. You will need your SEL-2032, a
PC or terminal with a serial port, and an SEL C234A cable to connect the PC
or terminal to Port F on the front panel of the SEL-2032. If you are using a PC,
you will also need a terminal emulation program.
Using Strong
Passwords
It is important that you establish strong password protection to safeguard
against unauthorized persons setting or resetting your SEL-2032 and the
devices attached to it. Strong passwords consist of six characters, with at least
one special character or digit and mixed-case sensitivity, but do not form a
name, date, acronym, or word. Passwords formed in this manner are less
susceptible to password guessing and automated attacks. Examples of valid,
distinct strong passwords include:
Ot3579 A24.68 Ih2dcs 4u-Iwg Ic-4+
NOTE: Do not use characters that
you have selected as LMD prefix
characters. See LMD Distributed Port
Switch Protocol on page 9.65 for a
description of LMD prefixes.
Used properly, passwords provide good protection against unauthorized
access. Make sure you choose strong passwords and record them in a secure
location. If your passwords are forgotten or lost, you will need to install the
main board password jumper in order to disable password protection long
enough to view them with the PAS command.
The SEL-2032 ships with factory-default passwords for Access Levels 1, 2,
and C. These passwords are shown in Tab le 3.1.
