By defining the power circuit records, you can track and manage your network assets in the Telecommunications Network Inventory application. ## Before you begin Role required: sn\_ni\_core.inventory\_admin, sn\_ni\_core.inventory\_agent ## About this task When you create a power circuit connection record, it creates a corresponding configuration item \(CI\) record in the circuit \[cmdb\_ci\_circuit\] table. To learn more, see [Data model](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/uses-for-network-inventory-data.md). ## Procedure 1. Navigate to **Workspaces** > **Network Inventory Workspace**. 2. Select the list icon \(\[Omitted image "ni-workspace-list-icon.png"\] Alt text: List icon.\), and then select **Inventory** > **Power Circuits**. 3. Select **New**. 4. On the **Details** tab, in the Circuit section, fill in the fields. To learn more about the fields, see [Power circuit form](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/power-circuit-form.md). 5. On the **Details** tab, in the Configuration section, fill in the configuration information for the power circuit. To learn about the configuration fields, see [Commonly used network asset instance configuration fields](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/commonly-used-tni-configuration-fields.md). 6. To create the Telecommunications Network Inventory attributes for the Power Circuit form, select **Set Inventory Attributes**. When you select the **Set Inventory Attributes** button, it creates the TNI CI Attributes record in the CI table as well as the Telecommunications Network Inventory CI Attributes tables and makes a relationship with the CI record. **Note:** If you select **Save** without selecting **Set Inventory Attributes**, it creates a CI record but not a Telecommunications Network Inventory CI record. In the network inventory workspace, the **Set Inventory Attributes** is visible only for the Telecommunications Network Inventory roles. 7. On the TNI CI Attributes form, fill in the fields. To learn more about the Telecommunications Network Inventory attribute fields, see [TNI CI Attributes form](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/ci-attribue-form.md). 8. Select **Save**. The Telecommunications Network Inventory attribute fields are displayed on the Power Circuit form after you save the TNI CI Attributes form. The **Set Inventory Attributes** doesn't appear when you reopen the CI record. 9. To add the attachments, such as graphics or documents, select the attachment icon \(\[Omitted image "attachments-icon.png"\] Alt text: Attachment icon.\). 10. Select **Save**. The related tabs appear on the form. You can view or modify the related tab information. To learn more about the related tabs, see [Related tabs in the Network inventory forms](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-network-inventory/telecommunications-network-inventory/inventory-related-tab.md). 11. To view the associated network inventories, select the brick icon \(\[Omitted image "infrastructure-relashionship.png"\] Alt text: Brick icon.\). The Infrastructure Relationships section shows all the associated network inventories grouped by the individual network asset instances. ## What to do next If you want to establish relationships with the other network assets, enter the details in the related tabs.
