Half-height FC drive power consumption figures are currently provisional. Final power consumption
figures will be available in a future edition of this document.
Airflow requirements
HP LTO Ultrium drives require forced airflow to ensure that components never exceed critical
temperatures.
Full-height drives
Airflow should be from front to back. The required flow depends on the ambient air temperature:
• 6 cfm for ambient air temperatures fluctuating in the range 10°C–35°C.
• 8 cfm for ambient air temperatures fluctuating in the range 10°C–40°C.
