Every dedicated server you ordered includes unlimited KVM access (KVM stands for Keyboard, Video, and Mouse, also it can be named KVM over IP — a virtual remote console for your server). Using this you can work with BIOS and OS directly without our tech support.
For all standard dedicated server plans KVM Virtual Media feature is available. It allows you to upload to the server any files — it’s usually used for ISO images for OS installation. You can then mount it via virtual DVD-ROM.
You can also power cycle your server via KVM web-interface, IPMIview app, or My account.
