3-1Chapter 3OperationThe 9M426-02 FDDI SmartSwitch Module is a three port switch module with twofront panel HSIM interfaces and one INB-2 backplane interface. This module,with the proper HSIM, may be used for an FDDI, ATM, WAN and otherhigh-speed connectivity for the SmartSwitch 9000 chassis.System Management BusesThere are two management channels within the SmartSwitch 9000 system: theSMB-1 and the SMB-10. These buses provide out-of-band management and inter-module management communication.SMB-1 BusThe SMB-1 is a 1Mbs management bus located within the SmartSwitch 9000. Thisbus is utilized by all diagnostic controllers in the system including connectivitymodules, power supply modules and the environmental module. The SMB-1transports inter-chassis information between system components, such as powerand environmental information, as well as diagnostic messages. Periodicloop-back tests are performed by all modules which share this bus to ensure thevalidity of SMB-1. In the event a failure is detected on SMB-1, the SMB-10 may beused as an alternate communication channel.SMB-10 BusThe SMB-10 is a 10Mbs management bus located within the SmartSwitch 9000which is also used for inter-chassis communication of modules as well as servingas an out-of-band management channel into the SmartSwitch 9000. The SMB-10 isexternalized from the chassis via an optional Ethernet Port Interface Module(EPIM) located on the front of the Environmental Module. Through an EPIMconnection, full SNMP management of the SmartSwitch 9000 is available out-of-
