Introduction
Overview of Main Features
Out-of-Band Remote Management
Out-of-band remote management uses a secondary communications channel, typically a
pair of dial-up modems, to connect to the management ports of remote equipment and to
control outlets that supply power to the remote equipment. With one USR4204 a single
channel can control up to four management ports and two power ports. The USR4204 allows
a Network Manager to select and control remote ports via a simple menu-driven interface.
Security
The USR4204 allows for one default Administrator and fifteen User accounts, and any User
can be granted Administrator privileges. Any Administrator can create, delete, or edit User
accounts, and has access to all USR4204 configuration menus. Any Administrator can also
assign access privileges for individual ports to each User. To deter unauthorized access, the
USR4204 is configured to lockout User or Administrator accounts and display a security
notification to Users and Administrators in the event of three consecutive failed attempts to
log-in as a User or Administrator.
