1-1 Chapter 1 Intr oduction The 9F310-02 and 9F315-02 are thr ee port switch modules with two front panel FDDI interfaces and one INB-1 backplane interface. The external FDDI networks are connected to the modules using standar d FDDI A/B ports on the front panel.
Introduction 1-2 interfaces provide frames filter ed, frames forwarded, and all Spanning T ree Protocol parameters. The 9F310-02 and 9F315-02 modules support the IETF FDDI MIB (RFC-1512), IETF MIB ll (RFC-1213), IETF BRIDGE MIB (RFC-1493), and a host of Cabletron enterprise MIBs.

3-1 Chapter 3 Operation The 9F310-02 and 9F315-02 modules are capable of bridging/switching any thr ee, of five possible interfaces, depending on how it is configured.
Operation 3-2 System Management Buses There ar e two management channels within the MMAC-Plus system: the SMB-1 and the SMB-10. These buses provide out-of-band management and inter -module management communication. SMB-1 Bus The SMB-1 is a 1Mbs management bus located within the MMAC-Plus.
3-3 DC/DC Conv er ter DC/DC Con verter The DC/DC converter converts the 48 VDC on the system power bus to the necessary operating voltages for its host network services module. The diagnostic controller monitors and contr ols the operation of the DC/DC converter .
Operation 3-4 The Host engine sends and receives packets via the CPU FPS Interface. This allows the bridge to perform spanning tree pr otocol and other bridging functions. The SMB Interfaces provide communication to the Host Engine for management functions and communication with other modules in the chassis.
