2-3 Installation The Reset Switch The Reset switch is located on the front panel, under the top plastic tab as shown in Figure 2-2. It serves two functions: • Pressing the r eset switch twice within three seconds causes the pr ocessor (i960) to reset. • Pressing and holding the switch on for thr ee or more seconds causes the module to shutdown.[...]

Installation 2-4 User -Accessible Components Figure 2-3 shows the various components that ar e accessible to the user . These consist of an eight-position dip switch (explained in the next section), replaceable PROMs and sockets for RAM. These will be used for future upgrades. Figure 2-3.

2-7 Installation Multi-Ring Out Capability Any port of the module may be configured as a ring-out port thr ough management software. In this configuration a stand-alone passive concentrator (such as an IBM 8228) may be added to the ring as shown in Figure 2-5. This allows for a star-wir ed network with the SmartSwitch 9000 at the center . Consult[...]

3-1 Chapter 3 Operation The 9T122-24 MicroLAN Module pr ovides connectivity between the front panel T oken 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 9T122-24 module connects to the FNB bus. Figure 3-1 is a block d[...]

Operation 3-2 Bridging The 9T122-24 is configured for SR T bridging. It will pass SR (Source Routing) frames between the rings and provides translation to transpar ent frames over the FNB to Ethernet and FDDI modules. For information on configuring the bridging function, see the addendum to the SmartSwitch 9000 Local Management User ’s Guide, c[...]

3-3 Operation Sour ce Route Bridging Source Route Bridging operates by transmitting frames over a designated r oute. Unlike T ransparent Bridging, all devices in a Sour ce Route Bridged (SRB) network “know” the locations of other stations within the network. Using a portion of the MAC frame header known as the RIF (Routing Information Field), t[...]

Operation 3-4 Fle xible Netw ork Bus (FNB) The FNB consists of two dual FDDI networks, the FNB-1 and FNB-2, providing up to 400 Mbps of data bandwidth. These FDDI networks are 100% ANSI FDDI-compliant supporting SMT (version 7.3), MAC, PHY , and PMD standards. This allows the FNB to traverse multiple SmartSwitch 9000 hubs, or connect to any ANSI FD[...]

3-5 Operation System Diagnostic Contr oller This diagnostic controller is composed of a Z-80 micr oprocessor and its supporting logic. The diagnostic controller is designed to contr ol the power-up sequencing of modules, monitor the 9T122-24 input and output power parameters, keep watch over the main host processor , as well as monitor the temperat[...]

Operation 3-6 The i960 core pr ovides the SNMP pr otocol stacks, as well as support for industry- standard MIBs. Additionally , Cabletr on enterprise-extension MIBs are supported for each media type. Advanced management services, such as the Distributed LAN Monitor , RMON, telnet and network address to MAC addr ess mapping, are also pr ovided by th[...]
