# Check in the server software

You can add Trellix DLP Discover server software to the ePO - On-prem Main Repository to prepare for deployment to enterprise servers. If you are using the Registered Documents feature, check in the DLP Server package and deploy it to the server required to act as the registration database. For Optical Character Recognition (OCR) feature, you must check in the OCR package.

Download the Trellix DLP Discover server software from [the Trellix download site](https://www.trellix.com/en-us/downloads.html) or use the Software Catalog.
