Vibration Non-operating: ● ½-sine: 160 cm/s, 2-3ms (~100g) ● square: 422 cm/s, 20g NOTE: Values represent individual shock events and do not indicate repetitive shock events. Operating random: 0.5g (rms), 5-300 Hz Non-operating random: 2.0g (rms), 10-500 Hz NOTE: Values do not indicate continuous vibration. ENERGY STAR The ENERGY STAR® program, a government-backed initiative, promotes energy efficiency by identifying ways to reduce energy consumption. Select HP workstations participate in the ENERGY STAR program. NOTE: ENERGY STAR is not supported on Linux-based workstations. For those workstations that support ENERGY STAR and have it enabled, the power management features will be set as follows: ● Monitor-Enters power savings mode after 15 minutes of inactivity. ● System-Enters standby mode after 30 minutes of inactivity. NOTE: If you must restore the operating system, reset the ENERGY STAR settings (if applicable) after the restore. To verify the factory default power settings for your product, select Start > Control Panel and doubleclick Power Options. ENERGY STAR compliance HP products purchased with the ENERGY STAR configuration are compliant with the U.S. Environmental Protection Agency (EPA) Computers Program. The EPA ENERGY STAR configuration does not imply endorsement by the EPA. As an ENERGY STAR partner, HP has determined that products with the ENERGY STAR configuration meet the ENERGY STAR guidelines for energy efficiency. The ENERGY STAR Computers Program was created by the EPA to promote energy efficiency and reduce air pollution through more energy-efficient equipment in homes, offices, and factories. HP products achieve this result by reducing the power consumption when not being used. ENERGY STAR on HP Workstations uses Advanced Configuration and Power Interface (ACPI) power management. The system can wake as a result of a user action (keyboard or mouse) or from the network or a modem. The Power Management feature, when used in conjunction with an external ENERGY STAR-compliant monitor, supports the power-down features of the monitor. The Power Management feature allows an external monitor to go into low-power mode when the Energy Save timeout occurs. NOTE: Using the ENERGY STAR Save Monitor feature with non-ENERGY STAR-compliant monitors might cause video distortion when the Energy Save timeout occurs. 14 Chapter 1 Product overview ENWW
