The H2GT48D card provides 48 MPLS GE electrical interfaces for 1000BASE-T access. It is applicable to all the ZXR10 8900E series switches and provides the Synchronous Ethernet, IEEE 1588v2, and OAM functions.
The H2GT48D card provides the following functions:
• Large switching capacity
It provides 48 GE electrical interfaces for wire-speed forwarding and supports large table entries and the MPLS function.
• Gigabit out-of-band communication
The MCS module communicates with the CPU of the card through this function, for example, downloading the CPU initialization information.
• EPLD online upgrade
The EPLD of the H2GT48D card provides the online upgrade function by simulating the JTAG interface.
• JTAG test
The H2GT48D card connects to the main chips of line interface cards through a daisy chain to conduct the JTAG test.
• Intelligent detection
Temperature, voltage, and power consumption monitoring circuits are designed on the card to implement real-time monitoring through the IIC bus.
• IPMC management and control unit
The IPMC of each line interface card connects to the IPMC of the MCS module through a bus to establish an intelligent platform management system.
• Synchronous Ethernet & IEEE 1588v2
It supports Synchronous Ethernet and IEEE 1588v2 time synchronization.
• Power supply management
A power management chip can control the power-on sequence of devices.
