CAUTION: To prevent improper cooling and damage to the equipment, do not block the ventilation openings. When vertical space in the rack is not filled by a VLS or rack component, the gaps between the components cause changes in airflow through the rack and across the servers. Cover all gaps with blanking panels to maintain proper airflow. Using a rack without blanking panels results in improper cooling that can lead to thermal damage. The Compaq 10000 Series racks provide proper VLS cooling from flow-through perforations in the front and rear doors that provide 64 percent open area for ventilation. CAUTION: If a third-party rack is used, observe the following additional requirements to ensure adequate airflow and to prevent damage to the equipment: • Front and rear doors-If the 42U rack includes closing front and rear doors, you must allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64 percent open area for ventilation). • Side-The clearance between the installed rack component and the side panels of the rack must be a minimum of 7 cm (2.75 in). Temperature requirements To ensure continued safe and reliable equipment operation, install or position the system in a well-ventilated, climate-controlled environment. The maximum recommended ambient operating temperature (TMRA) for the VLS system is 35° C (95° F). The temperature in the room where the rack is located must not exceed 35° C (95° F). CAUTION: To reduce the risk of damage to the equipment when installing third-party options: • Do not permit optional equipment to impede airflow around the VLS or to increase the internal rack temperature beyond the maximum allowable limits. • Do not exceed the TMRA. Power requirements Installation of a VLS must comply with local and regional electrical regulations governing the installation of information technology equipment by licensed electricians. This equipment is designed to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, see the product rating label or the user documentation supplied with that option. WARNING! To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply branch circuit that provides power to the rack. Consult the electrical authority having jurisdiction over wiring and installation requirements of your facility. 22 Hardware installation
