Connecting Power
The AC power cord shipped with the device connects the device to earth ground when plugged into an AC grounding-type
power outlet. The device must be connected to earth ground during normal operation. To connect power to the device, plug
one end of the AC power cord into the AC power appliance inlet on the back panel of the device. Plug the other end into an
AC power source.

13
Power ON/OFF Device
To power on this device, simply plug it into the wall. To power down the switch simply unplug the switch from it is power
cord.
Installing Equipment
You can mount this device into a standard 19-inch equipment rack. You can center- or front-mount the device in a rack.
Optional rack-mounting brackets are supplied with the device. Otherwise the devise can be placed on a flat shelf with the
adhesive feet applied to the bottom of the device.

The switch contains 8 1000BASE-T RJ45 ports. All RJ45 ports support automatic MDI/MDI-X operation, auto-negotiation
and IEEE 802.3x auto-negotiation of flow control, so the optimum data rate and transmission can be selected
automatically.
SFP Transceiver Slots
The S81 supports 2 Small Form Factor Pluggable (SFP) transceiver. In the default configuration, if an SFP transceiver
(purchased separately) is installed in a slot and has a valid link on the port, the associated RJ45 port is disabled. The
following table shows a list of transceiver types which have been tested with the switch. Please contact i3 International

Installing an Optional SFP Transceiver
It is possible to install or remove a mini-GBIC SF from a mini-GBIC slot without having to power off the switch. The mini-
GBIC slots are shared with the two 10/ 100/ 1000Base-T RJ-45 ports. If a mini-GBIC is installed in a slot, the associated
RJ45 port is disabled and cannot be used and operate only at full duplex. Half duplex operation is not supported. Ensure

14
the network cable is NOT connected when you install or remove a mini-GBIC.
To install a SFP transceiver:
Consider network and cabling requirements to select an appropriate SFP transceiver type.
Insert the transceiver with the optical connector facing outward and the slot connector facing down. NOTE: that
SFP transceivers are keyed so they can only be installed in one orientation.
Slide the SFP transceiver into the slot until it clicks into place.
Making Network Connections
The switch is designed to be connected to 10, 100 or 1000Mbps network cards in PCs and servers, as well as to other
switches and hubs. Each device requires an unshielded twisted-pair (UTP) cable with RJ45 connectors at both ends. Use
Cat 5e or 6 cables for 1000BASE-T connections, Cat 5 or better for 100BASE-TX connections.
•Attach one end of a twisted-pair cable segment to the device’s RJ45 connector.
•If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to
a modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections.”)
Otherwise, attach the other end to an available port on the switch.
NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem.
Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub.
•As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps)
or amber (100Mbps) to indicate that the connection is valid.
The punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel.
Instructions for making connections in the wiring closet with this type of equipment follows.
•Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.
•If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down
block is located, and the other end to a modular wall outlet.
•Label the cables to simplify future troubleshooting. See “Cable Labeling and Connection Records”.

When adding hubs to your network, please note that because switches break up the path for connected devices into
separate collision domains, you should not include the switch or connected cabling in your calculations for cascade
length involving other devices.

1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all
four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations,
Category 5e or Category 6 cable should be used. The Category 5e and 6 specifications include test parameters that are
only recommendations for Category 5. Therefore, the first step in preparing existing Category 5 cabling for running
1000BASE-T is a simple test of the cable installation to be sure that it complies with the IEEE 802.3-2005 standards.

Cable labelling and Connection Records
When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable
is connected. This will allow the user to easily locate inter-connected devices, isolate faults and change your topology
without wasting time unnecessarily. To best manage the physical implementations of the network follow these
guidelines.
•Clearly label the opposing ends of each cable.
•Using your building’s floor plans, draw a map of the location of all network-connected equipment. For each
piece of equipment, identify the devices to which it is connected.
•Note the length of each cable and the maximum cable length supported by the switch ports.
•For ease of understanding use a location based key when assigning prefixes to your cable labeling.
•Use sequential numbers for cables that originate from the same device.
•Differentiate between racks by naming accordingly.
•Label each separate piece of equipment.
•Display a copy of your equipment map including keys to all abbreviations at each equipment rack.
Troubleshooting
Most problems are caused by the following situations. Check for these items first when starting your troubleshooting:
Connecting to devices that have a fixed full duplex configuration.
•The RJ45 ports are configured as “Auto”. That is, when connecting to attach devices, the switch will operate in
one of two ways to determine the link speed and the communication mode (half duplex or full duplex).
•If the connected device is also configured to Auto, the switch will automatically negotiate both link speed and
communication mode.
•If the connected device has a fixed configuration, for example 100Mbps, at half or full duplex, the switch will
automatically sense the link speed, but will default to a communication mode of half duplex.
•Because the S81 Switch behaves in this way (in compliance with the IEEE802.3 standard ), if a device connected
to the switch has a fixed configuration at full duplex, the device will not connect correctly to the switch. The
result will be high error rates and very inefficient communications between the switch and the device. Make

16
sure all devices connected to the S81 Switch are configured to auto negotiate, or are configured to connect at
half duplex (all hubs are configured this way.)
Faulty or loose cables.
•Look for loose or obviously faulty connections. If they appear to be OK, make sure the connections are snug. If
that does not correct the problem, try a different cable.
Non-standard cables.
•Non-standard and miss-wired cables may cause network collisions and other network problems, and can
seriously impair network performance. Use a new correctly-wired cable. A category 5 cable tester is a
recommended tool for every 100Base-TX and 1000Base-T network installation.
Improper Network Topologies.
•It is important to make sure you have a valid network topology. If you no longer experience the problems, the
new topology is probably at fault. In addition, you should make sure that your network topology contains no
data path loops.
Check the port configuration.
•A port on your Switch may not be operating as you expect because it has been put into a “blocking” state by
Spanning Tree, GVRP (automatic VLANs), or LACP (automatic trucking). (Note that the normal operation of the
Spanning Tree, GVRP, and LACP features may put the port in a blocking state.) Or, the port just may have been
configured as disabled through software.
Troubleshooting Chart
Symptom
Action
System LED is OFF
Check connections between the switch, the power cord and the wall outlet
Contact i3 Tech support for assistance.
Link LED is OFF
Verify that the switch and attached devices are powered on.
Be sure the cable is plugged into the switch and the corresponding device.
If the switch is installed in a rack check the connections to the punch-down block and patch panel.
Verify that the proper cable types are used and its length does not exceed specified limits.
Check the adapter on the attacked device and cable connections for possible defects. Replace the
defective adapter or cable if necessary.
Slow file transfer or
there is performance
degradation
Make sure that the attached device is set to auto negotiate. Both the port and the device must be on
the same setting (Auto, Half or Full Duplex).
Power and cooling problems
If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet,
power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power
connections, power losses or surges at the power outlet. If you still cannot isolate the problem, the internal power supply
may be defective. Verify that all system components have been properly installed. If one or more components appear to
be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure
that all the other components are functioning properly.
In-Band Access
You can access the management agent in the switch from anywhere within the attached network using Telnet and a web
browser. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you
have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then
verify that you entered the correct IP address. Also, be sure the port through which you are connecting to the switch has
not been disabled. If it has not been disabled, then check the network cabling.

represented by the floppy disk in the upper right corner of the GUI after
clicking the “Apply” button will save the changes to the Switch’s
configuration and preserve the changes.
Switch Configuration
This part guides configuration and management of this switch through the web interface. With this interface, the switch is
easily configured and monitoed through any one port.
Start up by the following steps:
1. Place the switch close to your PC/NB that you intend to use for configuration. It will help you to check the status
of the switch by LED in front panel while working on your PC/NB.
2. Connect the Ethernet port of your PC/NB to any port on the front panel of the switch. Turn the switch on and make
sure the connectivity by checking LED in the front panel of the switch.
3. Configure your PC’s IP address the same subnet with the switch’s.
