Chapter 8 Rack Mounting the HP Netserver (2-Post) The white papers, particularly the HP Netserver High Density Rack Solutions Overview (LP 1000r and LP 2000r), provide rack information for HP Netservers in 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 multi-unit rack assembly is likely to exceed the room's ambient temperature. Ensure the temperature around 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 HP Netserver's fans will only operate correctly if both front and rear of the rack allow free air flow. • 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). 78

Rack Mounting the HP Netserver (2-Post)
78
The white papers, particularly the
HP Netserver High Density Rack Solutions
Overview
(LP 1000r and LP 2000r)
, provide rack information for HP Netservers
in 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 multi-unit rack assembly is likely to exceed the room's
ambient temperature. Ensure the temperature around 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 HP Netserver's fans
will only operate correctly if both front and rear of the rack allow free air
flow.
•
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).
