In this section:
The operating conditions for the Ribbon DSC Platform system depend on the specific configuration and the requirements of the cards used.
Due to the modular construction of the system, components could be added that change the system’s environmental constraints. Card-level components and power supply modules have their own operating temperature ratings. Refer to component-specific product manuals for operational details that may effect system performance.
The Ribbon DSC Platform is designed to meet NEBS and ETSI requirements. However, due to its high power requirements, the system can deviate from NEBS in order to align itself with industry power requirements and trends.
Note
The following sections provide you with general guidelines.
The source of these specifications is NEBS GR-63-CORE. The Ribbon DSC Platform was subjected to these environments and passed all testing.
