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 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, 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 earth grounding of
rack-mounted equipment. Give particular attention to supply connections
that are not direct connections to the branch circuit: for example, using
non-HP power strips.
