3-1 Chapter 3 Operation The 9F206-02 module, as shown in Figure 3-1, pr ovides two repeater ports that extend the FNB bus outside the MMAC-Plus chassis. No bridging or routing is done in this module. Each port connects to both rings (Primary and Secondary) on each FNB (FNB-1 and FNB-2).
Operation 3-2 System Management Bus 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. The 9F206-02 uses only the SMB-1 bus. The SMB-1 is a 1 Mbps management bus located within the MMAC-Plus.
3-3 CPU CPU The CPU handles all low level SMT functions as well as module configuration requests. The CPU is also r esponsible for all environmental, power and system level communication between modules in the MMAC-Plus chassis.
