| | | |
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 | | Indicates that a packet collision has been |
| Yellow | | detected on the indicated segment. |
Act | Flashing | | Indicates that the port is transmitting or receiving |
| Green | | 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).
