H1GF48A

H1GF48Aoverview

The H1GF48A card provides 24 GE optical interfaces. It is applicable to all ZXR10 8900E series switches.
The H1GF48A card provides the following functions:

• Large switching capacity
It provides 24 GE SFP optical interfaces that support full wire-speed transmission.

• 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 H1GF48A module provides the online upgrade function by simulating the JTAG interface.

• JTAG test
The H1GF48A module 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 module 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.

• Power supply management
A power management chip can control the power-on sequence of devices.
