Introduction
The 9F206-02 (as shown in Figure 1-1)is an FDDI repeater module for the MMAC-Plus that provides external access to the Flexible Network Bus (FNB) backplane via two sets of FDDI-compliant A/B ports. This allows the FNB to traverse multiple MMAC-Plus systems, or connect to any ASNI FDDI-compliant device in an FDDI network. The 9F206-02 module attaches to both FDDI networks on the FNB backplane, FNB-1 and FNB-2, but can be controlled separately with DIP switches or local management tools. The 9F206-02 can also be used to Dual-Home an MMAC-Plus chassis to multiple points in the network. Using standard FDDI chip-set technology, the 9F206-02 module completely re-times and regenerates data signals for error free transmission and guaranteed interoperability.
Features
System Management
The 9F206-02 requires minimal management. It can be completely managed and controlled through the SMB-1. The management features include the following:
•Front Panel Port Status
•Insertion/bypass Control (FDDI-1 and FDDI-2) and Status
•FPIM Identification (Front Panel)
Connectivity
The 9F206-02 uses FDDI Port Interface Modules (FPIMs) to provide several media options for the front panel (FNB-1 and FNB-2) interfaces. These FPIMs are available in various media types including the following:
•Multimode Fiber Optic (FDDI MIC)
•Single Mode Fiber Optic (FDDI MIC)
•Unshielded Twisted Pair (RJ-45)
•Shielded Twisted Pair (RJ-45)
•Multimode Fiber Optic (SC)
•Singlemode Fiber Optic (SC)
