Overview Image
The Ultrastar 8 is installed into a rack using a toolless-attach rail system. The rails are a two-piece
system with one rail that attaches directly to the chassis called the inner rail and the other that attaches
to the rack. The inner rail comes nested inside the outer rail and can be accessed by sliding it out of the
outer rail. The outer rails attach to the rack and receive the chassis to support it inside the rack. The outer
rails attach to vertical rack rails that should be set between 32 in.-36 in. The toolless design means that
an installer can attach these rails to a rack without any tools which simplifies installation. Once they are
attached, they can be secured with the included M5 screws and washers.
