Use OT devices to review the OT devices that are associated with the selected equipment model entity and its child entities. You can also select and associate other OT devices to the selected equipment model
entity.

## Before you begin

To associate additional OT devices to the selected equipment model entity, both the Operational Technology Manager and Industrial Process Manager applications must be installed.  
Role required: To add OT devices, the logged in user has to have a combination of the following assigned roles:

* cmdb_ot_viewer, cmdb_ot_editor or cmdb_ot_admin role
* cmdb_ot_isa_editor or cmdb_ot_isa_admin role

{#view-ot-assets-equipment-model-entity__ul_hyc_g22_b1c}  
Note:  
To learn more about assigning user roles, see [Assign Industrial Process Manager user roles](https://www.servicenow.com/docs/k7xk7yp8bCsDvCMvS6J7YA "Assign roles to your users so that you can control their access to the features, capabilities, and data in the Industrial Process Manager application.").

## About this task

Users with an assigned cmdb_ot_isa_admin role can view equipment model entities for any site. However, users with assigned cmdb_ot_isa_editor or cmdb_ot_isa_viewer roles can only access those sites that an administrator has
granted access to for specific users. To learn more about granting site access, see [Manage equipment model site access for non-administrators](https://www.servicenow.com/docs/UDlinluXJGy_FMZdcVIQ4A "Assign or remove non-administrator access to equipment model sites. You can create the user criteria to determine whether certain users can access the equipment model entities for specific sites.").
