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)
