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 airflow in any way. Disrupting the airflow can cause the enclosure to run the fans
at an excessive RPM.
The following rack airflow principles should be considered for best results:
• Controlled air conditioners that are located in the facility where the enclosure will be installed.
• The airflow in and out of the equipment must not be restricted.
6.4.1
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.
6.5
Grounding the Enclosure
The enclosure is designed to ground all components to the chassis base with the use of a properly grounded
receptacle. Ensure that there is sufficient electrical and mechanical connection from the chassis base to the
rack rails, and that the rack itself is tied to earth ground.
The unit must be grounded in accordance with all local/regional and national electrical codes.
6.5.1
Electrostatic Discharge
The enclosure is designed to dissipate all electrostatic discharges to the chassis base. Ensure that there is
sufficient electrical and mechanical connection from the chassis base to the rack rails, and that the rack itself
is tied to earth ground. It is recommend that suitable ESD precautions be observed during installation and
service operations
