Chapter 5: Hardware Reference
Before connecting any network device to this hub, please review Chapter 2 for information on system installation, Chapter 3 for a brief look at common network architectures, and Chapter 4 for information on system configuration via the menu-driven interface. This chapter describes the hardware features of the Fast EtherHub 3500 Series. If you are not sure how to make network connections, or do not understand the hub’s indicators, you should refer to this chapter.
The Fast EtherHub 3500 Series provides a manageable 100 Mbps Fast Ethernet stack. It also supports optional network expansion modules that can be used to connect the hub (or stack) to the extended network with 100BASE-TX (10BASE-T), 100BASE-FX or 100BASE-T4 media types. Moreover, these extender modules serve to break up the local collision domain, allowing you to overcome the limited network diameter (i.e., two-hub limit) normally associated with Fast Ethernet.
This hub provides a simple interface for configuring or monitoring network connections. Figure 5.1 shows the front panel, which includes a comprehensive array of indicators, 12 RJ-45 station ports, and a slot for plugging in an optional SmartExtender Module. Each Fast EtherHub 3500 model has similar indicators and other front panel components. However, note that LEDs corresponding to the SNMP agent (i.e., Master and Backup) are not provided for the Fast EtherHub-12i.
