Attaching the I/O Rack to a Concrete Floor Beneath a Raised Floor
The customer is responsible for obtaining the services of a mechanical contractor to
attach the rack-mounting plates on the raised floor with hardware that goes through the
raised floor into the concrete floor below the raised floor. The mechanical contractor
should determine that the raised floor support and the hardware used to attach the rack
mounting plates is sufficient to meet the customer’s requirements for the installation.
Note: Because of the length of the four rack-mounting bolts, the drawer located in the
bottom position of the rack

must

be removed to install the four rack-mounting
bolts to the floor.
1. Mark the floor around the edge of each leveling foot.
