Security
To control access to user interface functions, the Wide Bank 28 DS3 Multiplexer supports a
multiple-level user security system. Basic security, which allows users to be assigned access levels
and passwords, is supported by all Wide Banks. Enhanced security, available as the “Security
Upgrade” option, provides additional security features, including the ability to disable user
interfaces.
Basic Security
Basic security allows CLI users to be assigned access levels based on their requirements. The
access level determines which commands are available to the user. The basic security user
access levels are:
 admin – The admin user has access to all commands and has the sole authority to grant
others access to the system by adding and deleting user names and passwords. There can
be only one admin user within the system.
 rw (read/write) – An rw user has access to all commands except those for adding users,
deleting users, and setting user levels. The rw users are typically responsible for the day-
to-day operation of the system.
 ro (read only) – An ro user is limited to commands that display status and reports. The
ro access level permits technicians to monitor system operation and performance, but
prevents them from altering settings.
NOTE: In previous releases of the Wide Bank, the security access levels were Level 1,
Level 2, and Level 3. These levels correspond to admin, rw, and ro, respectively. If you
are upgrading firmware in a Wide Bank that supports the numerical access levels, the
Level 1 user is automatically converted to admin; Level 2 users are converted to rw; and
Level 3 users are converted to ro.
