Chapter 1: Basic Switch Parameters
30 Section I: Basic Operations
Changing the Manager and Operator Passwords
There are two levels of management access on the AT-9400 Switch:
manager and operator. When you log in as a manager, you can view and
configure all of a switch’s operating parameters. When you log in as an
operator, you can only view the operating parameters; you cannot change
any values.
You log in as a manager or an operator by entering the appropriate
username and password when you start an AT-S63 management session.
The default password for manager access is “friend.” The default
password for operator access is “operator.” Passwords are case sensitive.
To change the manager or operator password, perform the following
procedure:
1. From the home page, select Configuration.
The System page is displayed with the General tab selected by
default, as shown in Figure 1 on page 28.
2. In the Passwords section, enter the new values. The parameters are
described below.
Manager Password
Confirm Manager Password
You use these parameters to change the manager’s login password for
the switch. The password can be from 0 to 16 characters in length.
The same password is used for both local and remote management
sessions. To create a new password, enter the new password into both
fields. The default password is “friend.” The password is case
sensitive.
Caution
Do not use spaces or special characters, such as asterisks (*) and
exclamation points (!), in a password if you are managing the switch
from a web browser. Many web browsers cannot handle special
characters in passwords.
Operator Password
Confirm Operator Password
Use these parameters to change the operator’s login password for the
switch. The password can be from 0 to 16 characters in length. The
same password is used for both local and remote management
sessions. To create a new password, enter the new password into both
fields. The default password for operator is “operator.” The password is
case sensitive.
