1. The final ASHRAE class is determined by the hardware that is installed in the rack. Individual specifications
for each piece of hardware must be reviewed.
2. Derate maximum allowable dry-bulb temperature 1°C per 175 m above 950 m. IBM recommends a
temperature range of 18°C - 27°C (64°F - 80.6°F).
