# Operate as the initial setup user

An Initial Setup User (ISU) user can perform administrative tasks only on storage systems that do not have defined roles (authorization rules).

When Unisphere is first installed, there is a single user who is called the Initial Setup User (ISU). This user can perform administrative tasks only on storage systems that do not have defined roles (authorization rules). Once an Administrator or SecurityAdmin is assigned to a storage system, the ISU is not able to access or even see the system from the Unisphere console. Therefore, Dell Technologies recommends that users not operate in this role for too long.

When logging in to Unisphere as the Initial Setup User (ISU), the Initial setup user warning message is displayed. This message informs you that you can only access the listed storage systems because they do not have defined authorization rules. Once rules are defined for the storage systems, you are no longer able to access or view the storage systems as the ISU.

To continue to access or view a storage system while operating as the ISU, select the corresponding Assign Admin role to ISU option and click OK.

The main tasks of an ISU are:

- Create local users
- Add authorization rules

For more information about operating as the ISU, see the Unisphere for PowerMax Installation Guide.
