Mounting the Switch
The EZ Switch 10/100 can be placed directly on your desktop, or mounted in a rack.
Before you start installing the switch, make sure you can provide the right operating
environment, including power requirements, sufficient physical space, and proximity
to other network devices that are to be connected. Verify the following installation
requirements:
• Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3Hz). The switch’s
power supply automatically adjusts to the input voltage level.
• The switch should be located in a cool dry place, with at least 10 cm. (4 in.) of space
on the sides for ventilation.
• Place the switch out of direct sunlight, and away from heat sources or areas with a
high amount of electromagnetic interference.
• If you intend to mount the switch in a rack, make sure you have all the necessary
mounting screws, brackets, bolts and nuts, and the right tools.
• Check if network cables and connectors needed for installation are available.
Stacking Switches on a Flat Surface
The EZ Switch 10/100 can be placed anywhere there is enough flat space, such as
on a table or desktop.
1. Stick the self-adhesive rubber foot pads (that come with this package) on each
of the 4 concave spaces located on the bottom of the first switch.
2. Place the first switch on a firm flat surface where you want to install the stack.
3. Repeat step 1 for each switch before stacking them. The rubber foot pads
cushion the switch against shock/vibrations and provide space between each
switch for ventilation.

Quick Installation Guide
4
Connecting the Switch System
The EZ Switch 10/100 provides 16 RJ-45 ports on the base unit. Each of these ports
supports connection to 10Mbps Ethernet or 100Mbps Fast Ethernet, and supports
full or half-duplex operation. The transmission speed for each port is automatically
set by the switch to match the highest speed supported by the connected device.
The transmission mode can be set for each port using auto-negotiation.
Making a Connection to an RJ-45 Port
You can use straight-through twisted-pair cable to connect any RJ-45 port on the
switch to any device that uses a standard network interface such as a workstation or
server, or to a network interconnection device such as a bridge or router (depending
on the port type implemented).
1. Prepare the network devices you wish to network. Make sure you have installed
10BASE-T or 100BASE-TX network interface cards for connecting to the
switch’s RJ-45 station ports.
2. Prepare straight-through shielded or unshielded twisted-pair cables with RJ-45
plugs at both ends. Use 100-ohm Category 3, 4 or 5 cable for standard 10Mbps
Ethernet connections, or 100-ohm Category 5 cable for 100Mbps Fast Ethernet
connections.
3. Connect one end of the cable to the RJ-45 port of the network interface card,
and the other end to any available RJ-45 port on the switch. All RJ-45 ports
support 10Mbps and 100Mbps Ethernet connections. When inserting an RJ-45
plug, be sure the tab on the plug clicks into position to ensure that it is properly
seated. Using the switch in a stand-alone configuration, you can network up to
7 end nodes.
Caution: Do not plug a phone jack connector into any RJ-45 port. This may damage the
switch. Instead, use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
Notes: 1. When connecting to another compatible switch or hub, run straight-through
cable between MDI (daisy chain) and MDI-X (station) ports. You may also
attach to MDI-X (station) ports at both ends if you use crossover cabling.
(Refer to “Port and Cable Assignments” on page 10 for a description of
crossover cable).
2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
3. We advise using Category 5 cable for all network connections to avoid any
confusion or inconvenience in the future when you upgrade attached devices
to Fast Ethernet.
Restrictions on Cascade Length - The IEEE 802.3 standard recommends restricting
the number of hubs (i.e., repeaters) cascaded via twisted-pair cable to 4; while IEEE
802.3u provides even stricter recommendations for Fast Ethernet. Therefore, when
cascading devices other than this switch, please refer to the accompanying
documentation for cascade restrictions. However, 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.

Installing the Switch

Powering On the Switch
1. Plug the power cord into the power socket on the rear of the switch, and the
other end into a power outlet.
2. Check the LED marked Power on the front panel to see if it is on. The unit will
automatically select the setting that matches the connected input voltage.
Therefore, no additional adjustments are necessary when connecting it to any
input voltage within the range marked on the rear panel.
3. The switch performs a self-diagnostic test upon power-on. (Note that this test
takes several minutes to complete.)
Note: The unit supports a “hot remove” feature which permits you to connect or
disconnect twisted-pair or fiber cables without powering off the switch and without
disrupting the operation of the devices attached to the switch.
Verifying Port Status
Check each connection by viewing the port indicators shown in the following table.
Label Color Activity Description
Power Green On Power is supplied to the switch.
Off Power is disconnected.
Link/Act Green On The network port is connected
Blinking Packet transmission or reception is

Verifying System Operation
Verify that all attached devices have a valid connection. The switch monitors the link
status for each port. If any device is properly connected to the switch and
transmitting a link beat signal, the Link indicator will light up for the corresponding
port. If the Link indicator fails to light when you connect a device to the switch, check
the following items:
• Be sure all network cables and connectors are properly attached to the connected
device and the switch.
• See if your cable is functioning properly by using it for another port and attached
device that displays valid indications when connected to the network.
• Be sure no twisted-pair cable exceeds 100 meters (328 feet).
Applications
This switch segments your network, significantly increasing both bandwidth and
throughput. Any port on the switch can be attached to a hub (a shared collision
domain) or provide a dedicated link to a single network device (such as a workstation
or server). When a port on the switch is connected to a hub (a 10 or 100 Mbps
repeater), the bandwidth provided by that port is shared by all the devices connected
to the attached hub. However, when a port is connected to an end node or to a
device that breaks up the collision domain (e.g., another switch, bridge or router),
the attached device has access to the full bandwidth provided by that port.
Bridging Functions - This switch provides fully transparent bridging functions.
It automatically learns node addresses, that are subsequently used to filter and
forward all traffic based on the destination address. When traffic passes between
devices attached to the same shared collision domain, those packets are filtered
from the switch. But when traffic must be passed between unique segments (i.e.,
different ports on the switch), the high-speed switching fabric forwards the packets
at near zero latency.
Switching Functions - Store-and-forward switching is used to forward traffic to
other ports. This scheme ensures data integrity and provides a clean data stream.
Flexible Configuration - This switch is not only designed to segment your network,
but also to provide a wide range of options in setting up network connections. It can
be used as a simple stand-alone switch; or connected with standard repeater hubs,
switches, or other network interconnection devices in various configurations.

Troubleshooting
Diagnosing Switch Indicators
The EZ Switch 10/100 can be easily monitored through panel indicators to assist the
network manager in identifying problems. This section describes common problems
you may encounter and possible solutions.
Symptom:Link indicator does not light up (green) after making a connection.
Cause: Network interface (e.g., a network adapter card on the attached device),
network cable, or switch port is defective.
Solution: Verify that the switch and attached device are powered on. Be sure the
cable is plugged into both the switch and corresponding device. Verify
that the proper cable type is used and its length does not exceed specified
limits. Check the adapter on the attached device and cable connections
for possible defects. Replace the defective adapter or cable if necessary.
Symptom:Power indicator does not light up (green) after power on.
Cause: Defective power outlet, power cord, or internal power supply.
Solution: Check the power outlet by plugging in another device that is functioning
properly. Check the power cord with another device. If these measures
fail to resolve the problem, have the unit’s power supply replaced by a
qualified distributor.
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 as
explained in the previous section. However, if the unit powers off after running for a
while, check for loose power connections, power losses or surges at the power
outlet, and verify that the fans on the right side of the unit are unobstructed and
running prior to shutdown. If you still cannot isolate the problem, then the internal
power supply may be defective. In this case, contact your distributor for assistance.
Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (e.g., the power cord or network cabling),
test them in an alternate environment where you are sure that all the other
components are functioning properly.
