SuperSmart User’s Guide For example, if network utilization reaches 1%, the LED labeled 1% will light. However, if network utilization rises above 1% (e.g., 30%), the LED labeled 30 and all the other LEDs before it (i.e., 1, 5, and 15) will light in rapid succession. These LEDs monitor the share of valid network frames transmitted by this hub within a 10Mbps bandwidth. They provide a quick way to monitor the current traffic load relative to the network’s capacity. Collision Label (%) Color F

SuperSmart User’s Guide When more than 31 consecutive collisions occur on the cable segment connected to a port, that port is automatically partitioned by the hub. The F hub automatically reconnects this port when a data packet longer than 512 bits (normal) is transmitted or received by the partitioned port without collision. This applies to all RJ-45 station ports and the ALT PORT. Segment LED Indicators Color: Green Label: Function: Indicates which segment is attached to the hub. There are

SuperSmart User’s Guide TROUBLESHOOTING If the Link/Traffic LED does not light up when a device is connected to its corresponding port, check that both the hub and connected device are powered on. For devices connected to the hub using a twisted-pair cable, check that the cable length does not exceed 100 meters. You should have standard, straight cables and not cross-over or other specialized cables. Traffic Traffic refers to the movement of packets being received by the port. A port’s corres

SuperSmart User’s Guide The system tests each component one at a time. The unit will complete the test cycle even if a problem is detected on any of the components. If no lights are ON, this means that all the hub components passed the diagnostics. If any problems were detected, the corresponding LED will blink after test completion to indicate which component failed the test.

SuperSmart User’s Guide Station Ports The unit has sixteen RJ-45 station ports. Using twisted-pair cable, connect your workstation (via the network interface card’s port) to any available RJ-45 port. Port 16 can be converted into a daisy-chain port by enabling the Daisy-Chain switch (see the following Daisy-Chain Switch section for related information). Hence, this port can also be used to connect the unit to another compatible unit using twisted-pair cable. Daisy-Chain Switch This switch
