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 configured, 

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-defined 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 first enable and 

configure the feature via the System Parameters menu as described in this section, 

and then define 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 flyout 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 five different configuration 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.
