4.3.2 Logging Into the System
The first step in starting an operator session is to log into the system. You must enter a
password that allows you to perform the required tasks on the system. The initial (default)
login passwords correspond to four different access levels, each allowing you to perform
certain tasks. Table 4-1 lists the default passwords and describes the access levels.
The “Superuser” password is the highest level of access, followed by “Manager”, “Operator”,
and “Viewer” in sequence. Each level allows you to also perform all operations available to
the other levels below it. For example, if you log in under the “Operator” password, you can
configure the system and perform diagnostic tests, or you can simply view the current system
status and configuration data, which are the only tasks permitted under the “Viewer”
password.
All passwords are case-sensitive for maximum security. For example, the system handles
TechMan
,
TECHMAN
, and
Techman
as three different passwords.
You can change your Manager, Operator, and Viewer passwords at any time. See your system
administrator to change your password or access levels.
Table 4-1. Default Passwords and Access Level
To log into the system from a local terminal, proceed as follows. To log in from a remote PC
refer to details later in this reference manual.
1. Press <Enter>. The Login Screen depicted in Figure 4-6 should appear. If not, press
<Enter> repeatedly until it does.
2. If the Login Screen does not appear after you press <Enter> several times, check your
terminal settings (they should be 9.6 kbps, eight data bits, no parity, and one stop bit).
