3-1 Chapter 3 Operation The 9E312-12 module is a thirteen port device; twelve front panel ports, each repr esents a separate Ethernet collision domain and one port connected to INB1.
Operation 3-2 ENIB The Ethernet Network Interface Block (ENIB) converts Ethernet data packets received thr ough front panel ports into a common canonical format that allows the Fast Packet Switching Engine to determine the proper destination port.
3-3 INB NIB INB NIB Each module that attaches to the Internal Network Bus (INB ) has an INB Network Interface Block (NIB). The INB NIB converts canonical frames to fixed length data blocks for transmission onto the INB.
Operation 3-4 and control the SMB LANVIEW diagnostic LEDs. Although the system diagnostic controller and the main host pr ocessor can operate independently of each other if needed, they exchange information about each others status and overall module condition.
