Installing Components in the Rack Observe the general guidelines when installing your components: • Refer to the user documentation that was shipped with the component for detailed instructions on installing a specific component or third-party hardware. • Refer to Appendix A, "Electrostatic Discharge," before installing components into the rack. • Use the configuration prepared with the Rack Builder Online software as a guideline for installing the components. • Install the heavier components first from the bottom of the rack up. • Be sure to balance the weight load between bayed racks. For example, if you have several UPS units and several servers, do not install all of the UPS units into one rack. Instead distribute them evenly in the bottom positions of each rack. • Allow a minimum clearance of 76 cm (30 inches) between the wall and the rear of the rack to provide adequate access for installation and service.
