Port and Hub Status LEDs
LEDs Condition Status
Power Green Hub is receiving power.
Link Yellow Indicates a valid 10BASE-T connection between
port and attached device.
Green Indicates a valid 100BASE-TX connection
between port and attached device.
Partition Yellow Port has been partitioned due to an abnormal
condition.
Col Flashing
Yellow
Indicates that a packet collision has been
detected on the indicated segment.
Act Flashing
Green
Indicates that the port is transmitting or receiving
data.
Util% Green Shows segment bandwidth utilization at 4/16/32%.
Yellow Shows segment bandwidth utilization at 64%.
Verifying System Operation
Verify that all attached devices have a valid connection. The hub monitors the
link status for each port. If any device is properly connected to the hub and
transmitting a link beat signal, the Link indicator will light up for the
corresponding port. If the Link indicator fails to light, see Troubleshooting on
page 8.
Applications
These dual-speed CheetaHubs allow great flexibility in configuring your network.
You can use them to mix and match 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 - These CheetaHubs have an internal switching function
that can be used in a simple stand-alone configuration as illustrated on the next
page. 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 on the next page shows a sample configuration. When connecting to
10Mbps 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).
