Psychrometric Chart Showing Recommended And Allowable Operating Environments For The Tape Library; Equipment Environment Specifications For The Ts1170 Drive Model - IBM TS4300 User Manual

Notes:
• The chart is shown in SI (metric) units and a barometric pressure of 101.325 kPa (sea level).
• The recommended operating environment specifies a long-term operating environment that can result
in the greatest reliability and energy efficiency.
• The allowable operating environment represents where the equipment has been tested to verify
functionality.
