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 uneven loading plan to place the
heaviest components in the bottom of the rack, mounting all components as
low in the rack as possible.
• 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 – Maintain reliable grounding of
rack-mounted equipment. Give particular attention to supply connections not
directly connected to the branch circuit (such as, using non-HP power strips).
