2.3.9 GRF Operating Environment
As previously mentioned, the operating temperature should not exceed 53 °C (128 °F). Even though there is a buffer between the operating temperature and the warning temperature, it is best to keep the temperature within the operating level in order to minimize the possibility of damage to GRF components.
2.4 PSSP Enhancements
This section discusses the enhancements made to PSSP to accommodate the Dependent Node Architecture.
2.4.1 SDR Enhancements
As mentioned in Section 2.1.2, “Design Objectives” on page 8, the System Data Repository (SDR) needed to be extended to support the dependent node architecture. Two classes have been added to the SDR.
•DependentNode
•DependentAdapter
2.4.1.1 DependentNode Attributes
