Chapter 8 Installing the HP NetServer in the HP Rack System/E or Rack System/U • Reduced Air Flow - As you mount equipment in the rack, make sure that you allow enough air flow for safe operation of the equipment. Observe the minimum clearance dimensions listed in Appendix A, "Specifications." • Circuit Overloading - Make sure that the total configuration of equipment in the rack does not overload the supply circuit. To this end, check the nameplate ratings on all equipment. Consider the effect of circuit overloading on overcurrent protection and supply wiring. • Reliable Earth Grounding - Maintain reliable earth grounding of rack-mounted equipment. Give particular attention to supply connections that are not direct connections to the branch circuit: for example, the use of power strips.
