Dell Remote Access Card 4 (DRAC4) allows customers to effectively manage servers in remote locations where no administrative IT staff exists. It provides lights out management with continuous video that provides a graphical console regardless of the server's state and requires no operating system services or drivers. Virtual media support provides the server access to networked CD, floppy, and USB drives for server installation and updates (origin: Dell USA). The remote management is possible e.g. via web interface or via the provided integrated SSH daemon (running at port 22/TCP) based on Mocana SSH.
