5.3.4. Callback Security
The Callback function provides an additional layer of security when users attempt
to access command mode via modem. When this function is properly congured,
modem users will not be granted immediate access to command mode upon entering
a valid password; instead, the unit will disconnect, and dial a user-dened number
before allowing access via that number. If desired, users may also be required to re-
enter the password after the Outlet Managed PDU dials back.
In order for Callback Security to function properly, you must rst enable and
congure the feature via the System Parameters menu as described in this section,
and then dene a callback number for each desired user account as described in
Section 5.5. To access the Callback Security menu via the Text Interface, type
/F and press [Enter] and then select the Callback Security option. To access the
Callback Security menu via the Web Browser Interface, place the cursor over the
General Parameters link, wait for the yout menu to appear, and then Click on the
"Callback Security" link.
In both the Text Interface and Web Browser Interface, the Callback Security Menu
offers the following options:
• Callback Enable: This prompt offers ve different conguration options for
the Callback Security feature: (Default = On - Callback (Without
Password Prompt.)

Off: All Callback Security is disabled.

On - Callback (Without Password Prompt): Callbacks will be performed
for user accounts that include a Callback Number, and the login prompt will
not be displayed when the user’s modem answers. If the account does not
include a Callback Number, that user will be granted immediate access.

On - Callback (With Password Prompt): Callbacks will be performed for
user accounts that include a Callback Number, and the login prompt will be
displayed when the user’s modem answers (accounts that include a Callback
Number will be required to re-enter their username/password when their
modem answers.) If the account does not include a Callback Number, then
that user will be granted immediate access.

On - Callback ONLY (Without Password Prompt): Callbacks will
be performed for user accounts that include a Callback Number, and the
username/password prompt will not be displayed when the user’s modem
answers. Accounts that do not include a Callback Number will not be able to
access command mode via modem.
