Applications
These dual-speed CheetaHubs allow great flexibility in configuring your network. You
can use them in a stand-alone or multiple hub configuration to mix and match both
legacy Ethernet and Fast Ethernet network resources on your local network.
Moreover, you can easily extend your LAN by making a high-speed connection to a
collapsed backbone device (e.g., a switch or a router).
Stand-Alone Network - The CheetaHubs with the internal switching function
(EH3008A-SW, EH3016A-SW) can be used in a simple stand-alone configuration as
illustrated in the figure below. Regardless of whether you are making 10 or 100
Mbps connections with twisted-pair cable, limit the distance for each cable to 100
meters (328 feet).
Cascading Hubs with the Daisy-Chain Port - You can easily connect to another
hub or switch via the RJ-45 MDI daisy-chain port on the front panel. The figure
below shows a sample configuration. When connecting to 10 Mbps Ethernet, the
maximum number of hubs that can be cascaded is four (with up to 100 meters or
328 feet of cable allowed between each hub). However, when connecting to another
Fast Ethernet hub, the number of hubs that can be cascaded is limited to two, and
the total network span allowed is only 205 meters (672 feet).
Stack of Hubs - You can stack up to six hubs using the stack ports on the rear
panel. A CheetaHub stack can include up to 96 ports. Also note that if more than
one hub with internal switching (EH3008A-SW or EH3016A-SW) is placed in the
stack, switching between stack segments will be managed by the uppermost unit in
the stack, and internal switching will be disabled for all other units.
Connecting to a Network Backbone - You can easily connect to a collapsed
backbone switch via the RJ-45 MDI daisy-chain port on the front panel. Because a
switch breaks up the collision domain, it can be used to connect a group of
CheetaHub stacks.

Troubleshooting
Diagnosing Hub Indicators
The hub can be easily monitored through panel indicators to assist the network
manager in identifying problems. This section describes common problems you may
encounter and possible solutions.
Symptom: Link 10/100M indicator does not light up after making a connection.
Cause:
Network interface (e.g., a network adapter card on the attached device),
network cable, or hub port is defective.
Solution: Verify that the hub and attached device are powered on. Be sure the cable is
plugged into both the hub and corresponding device. Verify that the proper
cable type is used and its length does not exceed specified limits. Check the
adapter on the attached device and cable connections for possible defects.
Replace the defective adapter or cable if necessary.
Symptom: Power indicator does not light up (green) after power on.
Cause:
Defective power outlet, power cord, or internal power supply.
