Managing local accounts
The DSR web server provides local and login security through Administrator-defined user
accounts. By selecting Local Accounts on the side menu bar, Administrators may add and delete
users, define user preemption and access levels and change passwords.
User access levels
Accounts have two access levels: user and Administrator. Most switch management tasks can only
be performed by persons with Administrator level access.
Preemption levels
The preemption level of users determine whether they may disconnect another user’s serial or
video (KVM) session with a target device.
DSR web server Administrators may specify the preemption level for user accounts when an
account is created. The preemption level may be changed later.
Preemption levels range from 1-4, with 4 being the highest level. For example, a user with a
preemption level of 4 may preempt other level 4 users, as well as those with a level 1, 2 or 3 setting.
To change the default premption level (Administrator only):
1. Click Appliance - Appliance Settings - Ports - OSCAR.

To add a new user account (Administrator only):
1. On the side menu bar, select Local Accounts. The current user list will be displayed.
