SMB-10 Bus

Operation

SMB-10 Bus

The SMB-10 is a 10Mbs management bus located within the SmartSwitch 9000. This bus is used for inter-chassis communication of modules as well as serving as an side-band management channel into the SmartSwitch 9000.

The SMB-10 is externalized from the chassis via an optional Ethernet Port Interface Module (EPIM) located on the front of the Environmental Module. Through an EPIM connection, full SNMP management of the SmartSwitch 9000 is available side-band from user data. Modules that share the SMB-10 bus periodically send out loop-back packets to ensure the validity of SMB-10. If a fault is detected on the SMB-10, the SMB-1 can be used as an alternate communication channel by the modules.

System Diagnostic Controller

This diagnostic controller is composed of a Z-80 microprocessor and its supporting logic. The diagnostic controller is designed to control the power-up sequencing of modules, monitor the 9H423-28 module input and output power parameters, keep watch over the main host processor, monitor the temperature, and control the SMB LANVIEW diagnostic LEDs. Although the system diagnostic controller and the main host processor can operate independently of each other if needed, they exchange information about each other’s status and overall module condition. The information gathered by the diagnostic controller is available to the network manager via local/remote management and the LCD located on the environment module. The 9H423-28 is designed to continue functioning in the event of a diagnostic controller fault.

DC/DC Converter

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 controls the operation of the DC/DC converter.

INB Interface

The INB Backplane is designed to transport fixed-length data blocks between modules in the SmartSwitch 9000 using an INB Time Division Multiplexing (ITDM) design. The SmartSwitch 9000 INB bus delivers 2.5 Gbps of true data bandwidth with all control and management communication being serviced on the 8 bit out-of-band bus. The time slices of the INB manager operates in all three modes at once, without user intervention.
