Dell Lifecycle Controller GUI v2.30.30.30 User's Guide

If your organization’s users are on a private network that does not have access to external sites, specifically ftp.dell.com, you can provide firmware updates from a locally-configured FTP server. The users in your organization can access updates or drivers for their Dell server from the local FTP server instead of ftp.dell.com. A local FTP server is not required for users, who have access to ftp.dell.com through a proxy server. Check ftp.dell.com frequently to make sure your local FTP server has the most recent updates.
