Chapter 8 Rack Mounting the HP NetServer 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: l Optimum Operating Environment - The optimum operating environment for the HP NetServer LXr 8500 is in a environmentally 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 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 over-current protection and supply wiring. • Reliable Earth Grounding - Maintain reliable earth grounding of rackmounted equipment. Give particular attention to supply connections that are not direct connections to the branch circuit: for example, using non-HP power strips. 91

Chapter 8
Rack Mounting the HP NetServer
91
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
environment for the HP NetServer LXr 8500 is in a environmentally
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 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
over-current protection and supply wiring.
•
Reliable Earth Grounding -
Maintain reliable earth grounding of
rackmounted equipment. Give particular attention to supply connections
that are not direct connections to the branch circuit: for example, using
non-HP power strips.
