Rack installation
The G8272 switch includes a 2-post rack mount kit.
For 4-post rack installations, the G8272 switch supports the optional adjustable 19-inch, 4-post rail kit and
the air inlet duct (optional for the 4-post rail kit; supported only with the models with rear to front airflow).
When the G8272 switch (front to rear airflow) is installed in the Intelligent Cluster Rack (Machine
Type 1410) or Enterprise Rack (Machine Type 9363) as a part of a NeXtScale System solution, the
recessed 19-inch 4-post rail kit is required.
