H1XW4B

H1XW4B overview

The H1XW4B card provides four 10 GE optical interfaces. It is applicable to the ZXR10 8912E/8908E/8905E/8902E switches and supports full wire-speed MPLS forwarding.
The H1XW4B card provides the following functions:

• Large switching capacity
It provides four 10 GE SFP+ optical interfaces and supports full wire-speed MPLS forwarding. It supports the WAN mode, connects to the SONET/SDH network by using the SONET/SDH physical-layer transmission standard, and realizes highly reliable point-to-point data connections.

• 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 H1XW4B module provides the online upgrade function by simulating the JTAG interface.

• JTAG test
The H1XW4B 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.

• Synchronous Ethernet & IEEE 1588v2
It supports Synchronous Ethernet & IEEE 1588v2 time synchronization.

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