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.
The SmartWatch LED panel includes comprehensive indicators for monitoring the device and network status. A quick glance at
the front panel tells you if the unit’s power in ON, or if a problem exists on the network. The following sections describe the function of each indicator.

SuperSmart User’s Guide
PWR/CPU
Color: Green Label: PWR/CPU Function: Power indicator
LED Activity Condition Indication
STEADY LIGHT ON Unit is receiving power; CPU is running. BLINKING LIGHT ON Unit is receiving power; CPU is running. NO LIGHT OFF Power is disconnected; no power received.
Isolated
Color: Green Label: Isolated Function: Indicates the hub is isolated from Ethernet segment
of the FlexBus 1500 backplane.
LED Activity Condition Indication
STEADY LIGHT ON Hub is isolated from all segments. NO LIGHT OFF Hub is attached to one of the 3 segments of
the FlexBus 1500.
Utilization
Label (%) Color Function
1% 5% 15% Green Indicates percentage utilization of LAN 30% Amber (yellow) bandwidth. 65+% Red
The Utilization LEDs indicate the percentage of network bandwidth used by valid data. The hub updates this display every 0.5 seconds.
There are 5 LEDs representing the percentage of network utilization. The corresponding LEDs light to show that the percentage utilization of LAN bandwidth has reached this level. When active, these LEDs look like a stereo’s equalizer display.
2-2 Hardware Description
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 Function
1% 3% 5% Green Indicates the percentage of packet collisions 10% Amber (yellow) occurring out of the total packets received by 15+% Red the hub.
Collisions occur when two or more devices connected to a hub attempt to transmit data simultaneously on the network. When a collision occurs, devices pause and then re-transmit after a pseudo-random wait period. Because wait periods differ among devices, successive collisions become increasingly improbable.
The Collision LEDs assist the network manager in monitoring the percentage of packet collisions occurring relative to the total packets received by the hub. Similar to U tiliz ation LEDs, the Collision LEDs have 5 numbers representing collision percentage. When collisions reach a level marked on the LED display, the corresponding LED lights up.
For example, if packet collisions reach 1%, the LED labeled 1% will light up. However, if collisions go beyond 1% (e.g., 15%), the LED labeled 15+ and all the other LEDs before it (i.e., 1, 3, 5, and 10) will also light up in rapid succession.
Hardware Description 2-3
SuperSmart User’s Guide
When more than 31 consecutive collisions occur on the cable segment
F
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: Green Label:
Function: Indicates which segment is attached to the hub. There are 3 Ethernet segments embedded in the FlexBus 1500
ports located on the back plane of the SuperSmart hub. The unit can be attached to any one of the three Ethernet segments. The 3­segment LED indicator displays a combination of ON/OFF lig hts to show which segment the unit is connected to. The table below shows the possible LED display combination of the segment indicators marked "1 2 3" and their corresponding m eaning .

management channel (which is reflected via the Isolated LED).
Port Status Indicators
There are 17 pairs of port status LED indicators. Each pair consists of a Partition LED (top row) and Link/Traffic LED (bottom row ). Each pair (or column) has a label referring to the port number the LEDs monitor. For example, the port status LED pair labeled ALT monitors the optional port found at the rear panel (labeled ALT PORT). The other 16 pairs are for the RJ-45 ports on the front panel of the hub.
SuperSmart User’s Guide
Partition
LED Activity Condition Indication
STEADY RED LIGHT PARTITION Indicates port partitioning due to an
abnormal network condition.
NO LIGHT OFF Port is in good condition.
F
The Partition LEDs are also used as diagnostic LEDs. Please refer to the section on for more information.
Partition
Diagnostic Test LED Indicators
later in this chapter
A port is temporarily partitioned when a line error or too many collisions are detected on the attached segment. While it is automatically partitioned, the port continues to receive data from the segment. However, data is not transmitted onto the segment. When the problem is corrected or a valid data packet is received through the port, the port is automatically recon­nected. When partitioning occurs, the port’s corresponding Partition LED will be continually lit (RED light). Otherwise, this LED should be OFF (unlit).
Link/Traffic
LED Activity Condition Indication
STEADY GREEN LIGHT ON Indicates a valid link has been established on this
port.
BLINKING GREEN LIGHT ON Indicates the port is receiving packets; blinking is
proportional to the traffic passing through the port.
NO LIGHT OFF No valid link has been established on this port.
Link
The corresponding Link/Traffic LED should light up when a device (e.g., computer, hub or bridge) establishes a valid connection using the RJ-45 port. However, for the ALT port, no link connection is tested. The Link/Traffic LED for ALT only monitors the traffic condition.
Hardware Description 2-5
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 corresponding Link/Traffic LED will blink (ON) in proportion to the rate of traffic passing through the port. Through this LED, the network manager can easily view the activity on a port.
Diagnostic Test LED Indicators
The RJ-45 Partition LEDs not only monitor the partition or disabling of an RJ-45 port, they also monitor diagnostic test results.
LED Activity Condition Indication
BLINKING RED LIGHT ON The corresponding hardware component failed the
diagnostic test.
NO LIGHT OFF The corresponding hardware component
successfully passed the diagnostic test.
After power on, the hub automatically performs a diag nostic test. Seven hardware components are tested for SuperSmart hub. During this test, Partition LEDs indicate the success/failure of each test. The following table shows what each Partition LED m onitors.
Partition LED Indicator Test function/component
1 CPU 2 ROM 3 RAM 4 Serial communication controller 5 Hub control 1 6 Hub control 2 7 Timer
2-6 Hardware Description
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. Use this button for the following configuration functions:
Segment Setting

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. The thin coaxial cable that links the BNC ports may be extended up to 185 meters and have computers or other Ethernet devices attached to it. When connecting two hubs via BNC ports, there should be at least 0.5 meters (about two feet) of coaxial cable between the two BNC ports. If the hub is at the end of an Ethernet cable, plug and lock the 50-ohm () terminators to the T-type connector on the BNC port.
F
Terminate an open end of any T-type connector that is plugged into a BNC port with a 50-ohm () terminator. In particular, when a hub using the BNC port connection is at the end of an Ethernet segment, terminate the open end of the T-type connector with a 50-ohm () terminator. Also, if the BNC port is not used, plug a T-type connector to it and terminate both ends with a 50-ohm () terminator.
Power Socket
The power socket accepts AC power from 100 to 240V (+/- 10%) at 50 to 60 Hz (+/- 3Hz). The hub is equipped with a universal full-range power source.
Power Switch
The power switch is located at the right side of the rear panel. It is used to power the unit ON/OFF.

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. At most, 10 hubs can be linked together using the FlexBus 1500 connection. This type of architecture makes the system more flexible, provides better traffic load sharing and data protection, and improves network bandwidth utilization.
To make this architecture work for your system, plan your network setup well. Form a common domain for devices that need to communicate with each other by attaching them to the same segment. This way you can arrange network resources to balance traffic and thereby increase overall network efficiency.
To combine the segments into an interconnected network (while at the same time retaining the higher effective bandwidth and segment integrity provided by the multi-segment architecture), attach each segment to a bridge or similar interconnection device, such as Accton’s Secure Backbone Hub (EtherHub-SBH) or the Smart Ethernet Switching Hub (SwitcHub-8s).
Hot Remove Function
The SuperSmart hub supports a “hot remove” capability that allows you to connect/disconnect the SuperSmart hubs from the system without disrupting the network.

A "long press" has 2 functions. (1) It works like an [Enter]
key implementing the last selection displayed by the LED indicators for the current function. (2) It brings the system to the next configuration function.
A "short press" is used to switch between the selections
available within each function. For example, in Segment Setting, there are 4 selections available. By using a "short press" on the Configure button, you can move from one selection (e.g., Attach hub to Segment 1) to the next (e.g., Attach hub to Segment 2). Note, however, that a selection will only take effect after a "long press" on the Configure button.
If the button is not pressed within 10 seconds, the system
returns to normal operation effecting all changes made prior to selecting the current function.
Setup and Configuration 4-3
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. (Example: If the system is in Segment Setting function, see the LED display table under
Segment Setting in
this chapter).
3. If you want to implement the selection displayed for your hub,
proceed to step 4. Otherwise, move to the next selection using a "short press". Repeat a "short press" until you find the selection you want.
4. To implement your selection and continue on to the next
function, use a "long press".
