8.3 Airflow Consideration
The user needs to ensure both the front and rear of the 4U60 Storage Enclosure stay clear of any materials that may block
or disrupt the airow in any way. Disrupting the airow can cause the enclosure to run the fans at an excessive RPM.
The following rack airow principles should be considered for best results:
• Controlled air conditioners that are located in the facility where the enclosure will be installed.
• The airow in and out of the equipment must not be restricted.
8.3.1 Cooling the Enclosure
The 4U60 Storage Enclosure has an advanced thermal algorithm that monitors all of the temperature sensors in the system.
The enclosure makes adjustments to the fan speeds based upon the thermal sensors. The fan algorithm takes into account
for the temperature sensor warning and critical threshold limits set by SES. If any temperature sensor gets to the warning
limit, the fans speeds will increase to cool the component. If the enclosure encounters low temperatures, the system will
reduce fan speed in an attempt to conserve power and not over-cool the enclosure.
This algorithm is agnostic to effects of altitude and humidity. The algorithm simply works based on temperatures within
the system with emphasis on reducing power consumption.
8.4 Recommended Torque of Machined Screws
The following list is the recommended torque of the machined screws being added during the installation of the 4U60
Storage Enclosure.
