Fast EtherHub 3500 System User’s Guide
Product Overview 1-3
This hub can be used in a stand-alone configuration to form a
simple Fast Ethernet LAN networking 2 to 12 computers using
the RJ-45 station ports. Further network expansion can be
achieved using the embedded tri-segment backplane, the MDI
daisy-chain port, or one of the optional SmartExtender Modules.
Moreover, when stacked with other intelligent hubs through the
FlexBus ports and connected to the Fast EtherHub-12mi SNMP
management device, it can be monitored and controlled through
in-band or out-of-band channels.
Fast EtherHub-12mi SNMP
Intelligent Fast Ethernet Stackable Hub with 12 100BASE-TX Ports;
including SNMP Managment Support
This model conforms to both the IEEE 802.3u repeater
specification and the Simple Network Management Protocol
(SNMP). It not only functions as a 12-port Fast Ethernet
repeater, but also provides an on-board SNMP-based network
management agent for monitoring and controlling various
network components. It can monitor up to 6 intelligent hubs
connected to the same stack (including itself) through the
FlexBus port connection. This Fast EtherHub provides SNMP
management for the connected stack via various Management
Information Bases (MIBs), including MIB II, repeater MIB, and
Accton’s private MIB.
