The white papers, specifically HP Netserver High Density Rack Solutions
Overview (LP 1000r and LP 2000r), provide rack information for HP Netservers
in the high density racks and additional information for rack systems not listed in
this manual. You will need this information to complete a rack system installation.
Safety Precautions
Always keep the following safety and environmental issues in mind, especially if
you install the HP Netserver in a non-HP rack environment:
• Optimum Operating Environment – The optimum operating conditions for
the HP Netserver is in an environmental controlled computer room with a
temperature range of 20 to 22
°C (68 to 72°F) at 40 to 60% relative humidity.
• Maximum Ambient Temperature – Ensure the maximum ambient
temperature does not exceed 35 °C (95° F).
• Elevated Operating Ambient Temperature – The ambient operating
temperature within a closed or multi-unit rack assembly may 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, ensure you allow
enough air flow for safe operation of the equipment. The Netserver's fans
will only operate correctly if both front and rear doors of the rack allow free
air flow (perforated openings), or are removed.
• Mechanical Loading – Uneven mechanical loading within the rack can
cause hazardous conditions. To prevent this in your installation plans, place
the heaviest components in the bottom of the rack, mounting all components
as low in the rack as is practical.
• Circuit Overloading – Ensure 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 – Ensure rack-mounted equipment is reliably
grounded. Give particular attention to supply connections that are not direct
connections to the branch circuit (for example, use of non-HP power strips).
