Operation

The 9G421-02/9G429-02 module is a two-port Gigabit Ethernet device. Two front panel gigabit Þber optic ports provide connectivity through SC connectors.

As shown in Figure 3-1, Gigabit Network Interface Blocks (GNIBs) convert data packets received from the gigabit optics port into a canonical frame format before forwarding to the SmartSwitch ASIC. The Internal Network Bus Network Interface Block (INB NIB) converts data packets received from the INB into a canonical format before forwarding to the SmartSwitch ASIC.
