7. Securing the Cabinets
In areas that are prone to earthquakes, you should secure each SGI Origin 3900 system
to the computer room subfloor. Four M12 threaded weld nuts are located on the underside
of each cabinet frame for attachment to customer-supplied hold-down devices. The
attachment points are shown in Figure 7-1.
