Technical data

• Provide as many electrical outlets as are required for each additional
device, such as any table top device and console terminal.
2.1.4 Acoustics
The BA430/BA440 pedestal is designed for use in offices and other general
working areas. The following acoustic emission and heat dissipation levels
are for the BA430/BA440 pedestal. Levels may be lower, depending on the
kind and number of mass storage devices in the system. Data is measured
in accordance with ANSI S12.10–1985 (American National Standards
Institute) and ISO/DIS 7779 (International Standards Organization).
• LNPE (B) is the noise power emission level (A-weighted sound power
level) measured in bels re 1 pw (reference 1 picowatt). LNPE for the
BA430/BA440 enclosure is 5.8.
• LPA is the sound pressure measured in decibels at 1.0 m from the front
edge of the unit and 1.5 m above the floor. LPA for the BA430/BA440
enclosure is 43.
2.1.5 Heat Dissipation
Heat dissipation is measured in British thermal units (Btu). Maximum
heat dissipation in the BA430/BA440 enclosure is 2978 Btu/h.
2.1.6 Temperature and Humidity Values
