H2GF24D

H2GF24D overview

The H2GF24D card provides 24 MPLS GE optical interfaces. It is applicable to all the ZXR10 8900E series switches and provides the Synchronous Ethernet, IEEE 1588v2, and OAM functions.
The H2GF24D card provides the following functions:

• Large switching capacity
It provides 24 GE optical 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 H2GF24D card provides the online upgrade function by simulating the JTAG interface.

• JTAG test
The H2GF24D card connects to 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.
