Page 18: The Reset Switch
Installation The Reset Switch The Reset switch is located on the front panel, under the top plastic tab as shown in Figure 2-3. It serves two functions: • Pressing the reset switch twice within three seconds causes the processor (i960) to reset. -
Page 19: Chapter 3 Operation
Operation The 9T125-24 MicroLAN Module provides connectivity between the front panel Token Ring(s) and the FDDI rings on the backplane (FNB-1 or FNB-2). SmartSwitch 9000 modules connect to either the Internal Network Bus (INB) or the Flexible Network Bus (FNB) bus. The 9T125-24 module connects to the FNB bus. -
Page 20: Transparent Bridging
Operation Transparent Bridging Transparent Bridging is provided between all three interfaces and is accomplished by building a Source Address Table (SAT) from source MAC/physical addresses and using the SAT to make forwarding decisions. The 9T125-24 prevents unnecessary network traffic from passing through the module by implementing two separate filtering processes —... -
Page 21: Spanning Tree Algorithm
In order for source routing to work, the source station must determine the proper route to reach the desired destination. To accomplish this: 1. The source station sends out frames called All Route Explorer (ARE) or Single Route Explorer (SRE) frames onto the network. All Source Route Bridges recognize these frames and forwards them to their outbound ports. -
Page 22: System Management Buses
Operation System Management Buses There are two management channels within the SmartSwitch 9000 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 SmartSwitch 9000. This bus is utilized by all diagnostic controllers in the system including connectivity modules, power supply modules and the environmental module. -
Page 23: Dc/Dc Converter
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 controls the operation of the DC/DC converter. FNB Interface SmartSwitch 9000 modules are designed with one of two attachment options. One allows a module to dual attach to either FNB-1 or FNB-2;... - Page 24 Operation...
