H1GT28C12X4B

H1GT28C12X4B overview

H1GT28C12X4B is a card with 16 GE electrical interfaces, 12 combo interfaces and four 10GE optical interfaces. It provides 28-port GE and 4-port 10GE wire-speed access, is applicable to the full series of 8900E systems, and supports full wired-speed MPLS forwarding.
The H1GT28C12X4B card provides the following functions:

• Large switching capacity
Sixteen GE electrical interfaces, twelve combo interfaces and four 10GE optical interfaces are provided on the panel, with support for MPLS wire-speed forwarding.

• 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 H1GT28C12X4B module provides the online upgrade function by simulating the JTAG interface.

• JTAG test
The H1GT28C12X4B module 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 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.
