Chapter 13 Alternative Rack Mounting Always keep the following safety and environmental issues in mind, especially if you install the HP NetServer in a non-HP rack environment: • Maximum Recommended Ambient Temperature - The maximum recommended ambient temperature of the room is 35°C (95°F). • Elevated Operating Ambient Temperature - The ambient operating temperature within a closed or multi-unit rack assembly is likely to exceed the room's ambient temperature. Ensure the temperature within the rack itself does not exceed 35°C (95°F). • Reduced Air Flow - As you mount equipment in the rack, make sure that you allow enough air flow for safe operation of the equipment. • 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. l 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. Preparing for Installation Plan the placement of your HP NetServer LH 3000r and other rack components before proceeding with installation. Proper placement is vital for both safety and operating efficiency. For more details, see the HP NetServer Rack Installation Road Map. STOP! Read the HP Rack Installation Road Map before installing the HP NetServer LH 3000r. The road map contains important information you need to know for installing components in the rack. HP Rack Assistant can be used to plan the rack configuration.
