Chapter 1: Introduction Overview The SuperSmart (EtherHub-16se) hub is a powerful and innovative LAN network enhancement product. This hub supports a multi-segment bus architecture that enhances traffic flow and network bandwidth utilization. It offers the network manager a wide range of flexible configuration options, allowing you to effectively increase your network’s bandwidth.
SuperSmart User’s Guide Features of the SuperSmart Hub • One optional port (BNC, AUI or fiber-optic) for connecting to any Ethernet media via slide-in alternative module transceiver • Supports daisy chaining by using a daisy-chain switch to convert port 16 to a daisy-chain port • Automatic polarity detection and correction permits automatic recovery due to wiring errors • Automatically partitions any bad port to protect the network • Flexible installation for desktop, wall-mount, or rack installation (
Chapter 2: Hardware Description This chapter describes the hardware features of the SuperSmart hub. Before connecting any network device to the hub, please read this chapter carefully. For easier management and control of the hub, familiarize yourself with the front panel indicators and Configure button. Front Panel Display SmartWatch LED Panel The SmartWatch LED panel includes comprehensive indicators for monitoring the device and network status.
SuperSmart User’s Guide PWR/CPU Color: Label: Function: Green PWR/CPU Power indicator LED Activity STEADY LIGHT BLINKING LIGHT NO LIGHT Condition ON ON OFF Indication Unit is receiving power; CPU is running. Unit is receiving power; CPU is running. Power is disconnected; no power received. Isolated Color: Label: Function: Green Isolated Indicates the hub is isolated from Ethernet segment of the FlexBus 1500 backplane.
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.
SuperSmart User’s Guide F When more than 31 consecutive collisions occur on the cable segment connected to a port, that port is automatically partitioned by the hub. The 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: Label: Green Function: Indicates which segment is attached to the hub.
SuperSmart User’s Guide Partition F LED Activity STEADY RED LIGHT Condition PARTITION NO LIGHT OFF Indication Indicates port partitioning due to an abnormal network condition. Port is in good condition. The Partition LEDs are also used as diagnostic LEDs. Please refer to the section on Diagnostic Test LED Indicators later in this chapter for more information. Partition A port is temporarily partitioned when a line error or too many collisions are detected on the attached segment.
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.
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. Configure Button On the left front panel is a button labeled Configure.
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.
SuperSmart User’s Guide Rear Panel Displays This section describes significant features of the unit’s rear panel. Alternative Port POWER POWER SOCKET SWITCH Connectors ALT PORT ON FlexBus 1500 This device complies with Part 15 of the FCC Operation is subject to the following two (1) This device may not cause harmful (2) This device must accept any interference including interference that may cause IN OUT 100-250 VAC 50 -60Hz 1A OFF Figure 2.
SuperSmart User’s Guide ALT Port The slot labeled ALT PORT is for an optional slide-in transceiver module. Three types of transceiver modules are available AUI (10BASE2) for thick Ethernet cable BNC (10BASE5) for thin Ethernet cable (default) fiber optic (10BASE-F) BNC Module (10BASE2) The BNC module has a built-in transceiver with a BNC port for connection using thin coaxial cable. The BNC port can link up to 30 hubs on a thin coaxial cable segment.
Chapter 3: Hardware Installation This chapter describes how to install the hardware unit. Before You Begin 1. Before installing the hub, verify that the electrical values meet the following specifications. AC Power 100 to 240V (+/- 10%) Frequency 50 to 60Hz (+/- 3Hz) The hub is equipped with a power supply that automatically detects the input voltage level. 2. Leave at least 10 cm. of space at the front and back of the hub for ventilation. We recommend that the hub be installed in a cool and dry area.
SuperSmart User’s Guide Hardware Installation 1. Find a location for the hub. The unit is suitable for desktop or rack-mount installation. A good location is at the center of all the devices you want to link, close to the trunk segment, and near a power outlet. F The SuperSmart hubs can be stacked with other hubs using a mounting rack or directly on top of one another through the FlexBus 1500 ports.
SuperSmart User’s Guide Stacking Hubs without a Rack 1. Stick a self-adhesive rubber foot (comes with this package) on the 4 hollow spaces at the bottom of the first hub. 2. Place the first hub in the area where you want the stack to be installed. 3. Repeat step 1 for each hub before stacking them. The rubber feet cushion the hubs against shock/vibration and provide space between each hub for ventilation. SuperSmart Hub Stack (Up to 10 Hubs) Figure 3.
SuperSmart User’s Guide Mounting Hubs on a Rack 1. Confirm that the rack you will use is an EIA standard-size 19-inch rack. 2. Use the screws provided with the mounting rack to mount the hub using the hub’s mounting brackets. SuperSmart Hub Stack (Up to 10 Hubs) Figure 3.
SuperSmart User’s Guide Connecting the Hub System 1. Plug one end of the FlexBus 1500 cable (provided) in the BUS OUT port of the top hub and the other end to the BUS IN port of the next hub. Repeat this step for each hub in the stack. The top hub should only have one FlexBus 1500 port in use (BUS OUT). Refer to the FlexBus 1500 section in Chapter 2 for related information. 2. Cascade hubs using the daisy-chain port (Port 16).
SuperSmart User’s Guide 3. Connect the hub to an Ethernet trunk, if necessary. (Applies only to hubs with a slide-in module transceiver installed in the ALT PORT.) Plug the BNC T-type connector into the BNC port of the hub, and use this port to connect the device to the RG-58A/U thin Ethernet trunk. If the unit is at the terminal end of a trunk segment, connect a 50-ohm (Ω) terminator to the open end of the "T" connector.
SuperSmart User’s Guide The unit will automatically select the setting that matches the input voltage connected. Therefore, no additional adjustments are necessary when connecting it to any input voltage within the range marked on the rear panel. F The unit supports a "hot remove" feature which permits you to connect/disconnect cables without powering off the hub and without disrupting the operation of the hubs in stack.
Chapter 4: Setup and Configuration System Setup Diagnostic Tests Upon Power On Upon power on, the system performs an internal self-diagnostic test of major hub components. If any component fails during the test, the hub will try to complete the diagnostic procedure. Otherwise, the system will hang. For related information, refer to Diagnostic Test LED Indicators in Chapter 2. The following table shows the components to be tested.
SuperSmart User’s Guide Multi-Segment Architecture The SuperSmart hub supports multi-segment configuration through the FlexBus 1500 cabling. Three Ethernet segments are embedded in the hub’s FlexBus 1500 port providing 3 isolated segments (i.e., separate collision domains). You can choose to attach a hub to a segment, or to leave it isolated. Nodes attached to a specific segment (e.g., Segment 1) can only communicate with nodes attached to the same segment.
SuperSmart User’s Guide Using the Configure Button There are 5 configuration functions accessed in sequence using the Configure button, including: • • • • Segment Setting Demo Function Diagnostic Function Reset Function. A "long press" on the button allows you to switch from one function to the next. While a "short press" switches between selections within each function. LED indicators light up to indicate which configuration function the system is in.
SuperSmart User’s Guide To summarize, 1. Access configuration functions by using a "long press". LEDs light up to indicate the current configuration function. (Example: One of the Segment LEDs will BLINK to indicate that the system is in Segment Setting mode.) 2. Compare the LED display you see on the hub’s front panel with the appropriate LED display in the succeeding pages. Each LED display corresponds to a selection within a function.
SuperSmart User’s Guide Selections Available This section shows the selections available for each function and the corresponding LED display. The functions are listed here in sequence. Segment Setting Active LEDs: Segment LEDs Attach the hub to one segment.
