2-1 Chapter 2 Installing the Modules The SmartSwitch 9000 module may be installed into any of the 14 slots that a r e available. T o install, follow the steps below: 1 .
Installing the Modules 2-2 Figure 2-1. Installing the Module Metal Back-Panel Module Guides Module Jack for ESD Wrist Strap Plastic Tab W arning: Ensure that the circuit card is between the card guides. Lock do wn the top and bottom plastic tabs at the same time, applying e ven pressure.
2-3 Installing the Modules Installing EPIMs This section contains procedur es on how to add/replace an Ethernet Port MicroLAN Module (EPIM). After installing the EPIM, refer to Appendix A to verify proper EPIM operation.
Installing the Modules 2-4 Installing the EPIM T o install an EPIM: 1. Remove the coverplate or the EPIM (whichever applies). 2. Slide your new EPIM into place, making sure the connectors on the r ear of the module and inside the HUB attach properly .
2-5 Installing the Modules The Reset Switch The Reset switch is located on the front panel, under the top plastic tab, as shown in Figure 2-4. (Under the right-side tab on the 9E138-36.) It serves two functions: • Pressing the Reset switch twice within thr ee seconds causes the processor (i960) to reset.
Installing the Modules 2-6 User -Accessible Components Figure 2-5 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.
2-7 Installing the Modules Setting the Module Car d DIP Switch An eight-switch DIP switch is located on the module car d, as shown in Figure 2-5 and Figure 2-6.

3-1 Chapter 3 Operation The Ethernet MicroLan Switch Modules pr ovide connectivity between four interfaces: the three fr ont panel Ethernet 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.
Operation 3-2 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.
3-3 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 se.
Operation 3-4 i960 Core The i960 core in the FNB module serves two major functions: it pr ovides the packet forwarding logic and performs all network management services. FNB modules can be configured to r un as layer 2 bridges, layer 3 routers, or as Fast Packet Switches.
