10.4 ESD
The enclosure is designed to dissipate all electrostatic discharge (ESD) 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. Precautions must be taken to ensure that the system is
not exposed to ESD while handling components or servicing the unit.
The unit must be grounded in accordance with all local/regional and national electrical codes.
10.5 Enclosure Cooling
The Ultrastar Data102 has an advanced thermal algorithm running within the logical enclosure
services process called the SEP that monitors all of the temperature sensors in the enclosure. The
SEP makes adjustments to the fan speeds based upon the thermal sensors. The fan algorithm takes
into account the component and the warning and critical threshold limits defaulted and managed
by the SEP controller. If any temperature sensor exceeds the temperature threshold configured in
the SES pages, the fan speed will increase to cool the enclosure. If the enclosure encounters low
temperatures, the enclosure 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 works
based on temperatures within the enclosure with emphasis on reducing power consumption.
