System Environmental
Specs Values are subject to change without notification and are for reference only.
Performance of system, options, and ancillary equipment will vary depending on the system
configuration.
Levels presented do not account for non-HP/Compaq installed hardware.
Ambient Air
Temperature Operating 32° to 104° F (0° to 40° C) at sea level with an
altitude de-rating of 1.0°C per every 1000 ft
(300 m) above sea level to a maximum of
8000 ft (2500 m), no direct sustained sunlight.
Maximum rate of change is 77°F/Hr (25°C/Hr).
The upper limit may be limited by the type and
number of options installed.
Storage -22° to 149° F (-30° to 65° C)
Maximum rate of change: 410°F/Hr
(210°C/Hr).
Humidity Operating 10% to 90% relative humidity (Rh), 86°F
(30°C) maximum wet bulb temperature, non-
condensing.
Storage 10% to 95% relative humidity (Rh), 101.66°F
(38.7°C) maximum wet bulb temperature,
non-condensing.
Altitude Operating 0 to 10,000 feet (0 to 3048 meters) - This
value may be limited by the type and number
of options installed. Maximum allowable
altitude change rate is 1,000 ft/min (304.8
m/min).
Non-Operating 0 to 30,000 feet (0 to 9,144 meters) -
Maximum allowable altitude change rate is
1200 ft/min (365.76 m/min).
Shock Listed are the levels of shock the product can withstand with NO
damage being incurred. The values represent peak input acceleration
during a 2 to 3 ms half-sine shock pulse, 11 ms trapezoidal shock pulse.
Non-Operating 35G's (Half-sine Shock)
35G's (Trapezoidal Shock)
Vibration Listed are the levels of vibration the product can withstand with NO
damage being incurred. The values represent a flat random vibration
input acceleration profile across the given frequency range.
