IBM 9077 GRF Operating Environment, Pssp Enhancements, SDR Enhancements, DependentNode Attributes

IP/SONETThe IP/SONET OC-3c is a single-ported card that allows the user to connect to a digital network using a transmission format known as Synchronous Optical Network protocol (SONET). This standard is increasingly popular in the telecommunications industry.

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

The attributes of the DependentNode class are described in Table 2:

Table 2. DependentNode Attributes

User Defined	System Defined
node_number	switch_node_number
extension_node_identifier	switch_number
reliable_hostname	switch_chip
management_agent_hostname	switch_chip_port
