CPU Card CPU Card User Screens and Settings
The CPU card has numerous settings that you must configure. The System Main Screen
displays the status of each CPU card (active or redundant), the type of card installed, and the
voice and host software versions currently installed on that card. The settings are described in
the next few sections of this chapter.
The bottom highlighted line of the above screen shows a series of actions you can perform in
this menu. To perform an action, press the letter key associated with the capital letter of the
desired action. For example, to save your card option settings after making them, press “
s
” to
invoke the
Save
command. Table 4-1 lists and describes these actions.

4.3.1.1 Changing Your Passwords
You may want to change your system access passwords frequently, in order to maintain
optimum security on your network. The best passwords are at least 6 and no more than 12
characters long, are not found in a dictionary, and contain both letters and numbers. Because
the system is case-sensitive for password entries, you can mix upper-case and lower-case
letters to provide more possible passwords.
The system provides three editable passwords. Each represents a different level of access that
allows an operator to perform certain tasks on the system after logging in.
To change a password, first log into the system under the
Manager
access level password,
then choose the CPU card from the System Main Screen. Then, in the CPU Card Main Screen
(

Figure 4-1), highlight the password you want to change, press the <Enter> key, type the new
password over the current one, and press <Enter> again. Finally, make sure the new password
appears as you want (remember that passwords are case-sensitive), and save your changes.
Action Function
Save Saves changes to settings.
Undo Returns all settings to the last saved state.
Refresh Updates certain time-related information fields that are not automatically
updated (i.e. performance and test data).
Prt Allows the user to print alarms to a remote device through the modem and/or
the DB-9 computer port on the Interface Card. Refer to the “Printing Alarms
Remotely” section later in this chapter.
tcp/Ip Allows the system to communicate with a Network Management System via
SNMP or TELNET. Information can be transmitted locally via the DB-9
connector on the Interface card or over a WAN link (either DS0 or FDL) to the
NMS. This card records statistics for a variety of network functions. Refer to
the “TCP/IP Network Management” section later in this chapter.
Main Returns you to the System Main Screen. If you made changes to any card
settings but did not save them yet, you will be prompted to save or lose those
changes before exiting.
