Introduction
The CheetaHub Power-3008N/3016N provides 8 (or 16) RJ-45 ports for 10 Mbps or
100Mbps Ethernet connections (detected by auto-sensing). These dual-speed stackable hubs contain two internal repeater buses – one for 10 Mbps traffic and another for 100 Mbps traffic. Traffic passing between attached devices that operate at the same speed is confined within the appropriate repeater bus.
Note: The EH3016N/SW also includes a BNC on the rear panel.
In the CheetaHub Power-3008N-SW/3016N-SW, an internal Ethernet switch, consisting of a 10 Mbps and a 100 Mbps switching port, is used to link the repeater buses. Only if traffic has to be passed between a 10 Mbps and a 100 Mbps device, if the destination address is not found in the address table, or broadcast traffic is sent, will data be forwarded to the other repeater bus. These hubs are designed to perform switching between the 10 Mbps and 100 Mbps repeater buses for the individual hub and for the attached stack.
These stackable hubs provide an ideal bridge between 10 Mbps and 100 Mbps Ethernet networks, all for a price that's comparable to a standard Ethernet or Fast Ethernet hub. Moreover, the smart design built into the display panel provides a friendly interface that simplifies installation and network troubleshooting.

Description of Hardware
These four stackable hubs provide 8 (16) RJ-45 dual-speed ports (10/100 Mbps). Each of these ports automatically senses the speed of the attached device, and channels the data to the appropriate backplane (i.e., the 10 or 100 Mbps repeater bus). Hubs with the internal switching function (EH3008N-SW and EH3016N-SW) contain a 2-port switch that connects the two repeater buses. The two repeater buses are extended across the stack backplane (via the cable connection to the stack ports) to the other hubs in the stack. Up to six hubs can be stacked together.
The CheetaHub Power-3008N/3016N detects the speed of the device connected to each RJ-45 port, and directs traffic to the corresponding 10 or 100 Mbps repeater bus as required. However, when a CheetaHub Power-3008N-SW/3016N-SW is included in the stack, the learning function of this hub stores the node address and the correponding segment number (i.e., bus 1 or 2) of each incoming packet in a routing table. This information is subsequently used to pass traffic to the segment containing the destination node. By confining traffic to its respective collision domain, and only forwarding traffic to the other segment when required, the overall load on the network is significantly reduced.
