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.
