# Site Collectors Setup
For on-premises systems, such as Active Directory, where servers are physically located on your premises, you need to set up site collectors to facilitate accessing data sources. A site collector is a virtual appliance.
After you set up a site collector, you enter its name when you set up certain on-premises data sources. This is described in the section [*On-Prem Data Sources*](/technical-documentation/admin-guides/epiphany-intelligence-platform-administrator-guide/administration/source-management/on-prem-data-sources.md).
## **Adding a New Site Collector**
1. In the left navigation menu, expand **Source Management** and then select **Configuration.**
2. Select **New** **Collector**.
3. Enter the **Name** of the site collector. You can name it anything meaningful. You will use the name when you set up an on-premises data source. This is a required field.
4. In **Site**, enter the location of the collector. This can be a physical location. You can set up a collector that collects data in only one location instead of your entire wide area network. This is a required field.
5. Optionally, enter any **Notes**.
6. Click **Save**.
7. At the top of the Site Collectors pane, expand **Select a Collection Time** and select the time you want collections to occur. This is the time each day that Epiphany will run your data collection.\

## Editing an Existing Site Collector
Once a site collector is added, you can view it by expanding **Site Collectors.** The image below shows three site collectors called Agency A, HQ, and Agency B.
1. Expand the **Actions** drop-down and select **Update**. \
2. Make any edits to the Name, Site, or Notes and then select **Save**.

You can also use the Delete item in the Actions drop-down to delete site collectors you're no longer using. The other items in the Actions drop-down are used when setting up data sources, They are described in detail in the instructions for setting up specific data sources in the [*Data Sources*](/technical-documentation/data-sources.md) section.
