C.2 Environmental Specifications
The Netra CT 820 server is designed for harsh environments. The chassis features
sturdy steel and aluminum construction with a corrosion resistant finish.
Due to the modular construction of the system, components could be added that
change the system’s environmental constraints. Board-level components and power
supply modules have their own operating temperature ratings. Refer to component-
specific product manuals for operational details that may affect system performance.
