S1GF24A

The S1GF24A card provides 24-gigabit optical interfaces for gigabit wire-speed access. The S1GF24A card is applicable to all the ZXR10 8900E series switches and can support the wire-speed MPLS access through a GE interface.

The S1GF24A card provides the following functions:

• Data switching with a large capacity
The S1GF24A card provides 24 gigabit SFP optical interfaces and supports MPLS full wire-speed transmission.

• Gigabit out-of-band communication
This function is used for communication between the S1GF24A card and the CPU of the card, and between the S1GF24A card and the main control card, for example, downloading the CPU initialization information.

• EPLD online upgrade
The EPLD of the S1GF24A card provides the online upgrade function by simulating the JTAG interface.

• JTAG test
The S1GF24A card connects to the main chips of line interface cards through a daisy chain to conduct the JTAG test.

• Intelligent detection
The card provides temperature, voltage, and power consumption monitoring circuits 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 card 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
