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.

Color
Green
Amber (yellow)
Red
Function
Indicates the percentage of packet collisions
occurring out of the total packets received by
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 Utilization 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
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.

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.

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. 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

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.

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 (Ω) 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 (Ω) 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 ( Ω) terminator. Also,
if the BNC port is not used, plug a T-type connector to it and terminate
both ends with a 50-ohm (Ω) 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.

in a cool and dry area.
3. If you plan to stack the hubs in a mounting rack or directly
on top of one another, make sure you have all the mounting
screws, brackets, and tools you need for proper installation.
3-1
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. Refer to the sections on Stacking Hubs without a Rack
or Mounting Hubs on a Rack for a description of these methods.
If you don’t want to stack the hub with other hubs now, skip this
step and proceed to Connecting the Hub System .
If you plan to use the hub in a stand-alone configuration, go to Step
4 under Connecting the Hub System .
2. Connect the hub to compatible hubs (e.g., another SuperSmart hub)
through the FlexBus 1500 ports. Use either of the two methods
mentioned in this section.

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). RJ-45
port 16 can be converted into a daisy-chain port using the
daisy-chain switch. To daisy chain, slide the daisy-chain
switch to the right ( ), and plug one end of a twisted-pair
cable to Port 16 and the other end to any RJ-45 port of a
compatible hub. (However, you must not plug both ends to
a daisy-chain port.) Using this type of connection, you can
cascade up to 4 hubs.
I
Do not plug in a phone jack connector to the RJ-45 port. This may
damage the hub. Instead, use only twisted-pair cables with RJ-45
connectors that conform with FCC standards.
Hardware Installation

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. If the Ethernet BNC trunk port has
no connection, plug in the BNC T-type connector and lock
both ends with a 50-ohm (Ω) terminator.
4. Connect workstations to the hub.
Prepare the workstations you wish to network. Make sure
they have properly installed 10BASE-T network interface
cards, or external 10BASE-T transceivers.
Prepare twisted-pair cables with RJ-45 plugs at both ends.
The length of each cable should not exceed 100 meters.
Connect one end of the cable to the RJ-45 port of the PC’s
network interface card. Connect the other end to an

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.

During Normal Operation
You can use the Configure button any time you want the
system to perform a diagnostic test. However, when testing
begins, the system leaves normal operation. If no problem is
encountered by diagnostics, the system automatically returns to
normal operation.

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.

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.
Before using the Configure button, remember that:
• A "long press" means pressing the Configure button for more
than 2 seconds and then releasing the button. While a "short
press" means pressing the Configure button and immediately
releasing it.
• 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".
