Power On
After all network cables are connected, plug the power cord into the
power socket on the back panel and the other end into a power
outlet. Turn the power On using the power switch on the back panel.
Check the front panel Power indicator to see if power is properly
supplied. The Switch uses a universal power supply that requires no
additional adjustment.
3. Connecting to the Network
This section provides the installation procedure and instructions for
assigning IP address.
3.1Pre-InstallationRequirements
Before you start hardware installation, make sure your installation
environment has below items:
PCs with 10/100Mbps Ethernet NICs/100/1000Mbps Fiber
NICs:
Your PC must have a standard Ethernet interface to connect to
the Switch.
UTP cable with RJ45 connectors/ Fiber cable with MT-RJ/
VF-45 connectors: Check if the cable and connectors work
properly.
A power outlet: 100 to 240V AC at 50 to 60 Hz: Make sure that
the Switch power is accessible and cables can be connected
easily.
Dedicated power supply: Use a dedicated power circuits or
power conditioners to supply reliable electrical power to the
network devices.
A dry cool place: Keep the Switch away from moisture. Avoid

SMC-EZ1026DT V.2
10
direct sunlight, heat source, and high amount of electromagnetic
interference around.
Mounting tools: If you intend to mount the Switch on a rack,
make sure you have all the tools, mounting brackets, screws etc.
Caution:
Cabling must be away from sources of electrical noise such as
radio, computers, transmitters, broadband amplifiers, power
lines and keep away from TVs, hair dryers, and microwave.
 Airflow around the Switch and through its vents on the rear
cannot be restricted.
3.2 Mounting the Switch
The SMC-EZ1026DT V.2 Switch is suitable for use in an office
environment where it can be rack-mounted in standard EIA 19-inch
racks or standalone.
Desktop Mounting
1. Set the Switch on a sufficiently large flat space with a power
outlet nearby, and about the center of all networked devices.
2. Make sure mounting surface on the bottom of the Switch is
grease dust free.
3. Remove adhesive backing from your Rubber Feet.
Figure 3-1. Attaching Rubber Feet to each corner
on the bottom of the Switch

4. Apply the Rubber Feet to each corner on the bottom of the Switch.
These footpads can prevent the Switch from shock/vibrations.
Caution: Do not place objects on top of the Switch.
Rack-mounted Installation
The SMC-EZ1026DT V.2 Switch come with a rack-mounted kit and
can be mounted in an EIA standard size, 19-inch Rack. The Switch
can be placed in a wiring closet with other equipment.
Perform the following steps to rack mount the Switch:
A. Position one bracket to align with the holes on one side of the
Switch and secure it with the smaller bracket screws. Then attach
the remaining bracket to the other side of the Switch.
Figure 3-2. Attach mounting brackets with screws
B. After attached both mounting brackets, position the
SMC-EZ1026DT V.2 Switch ( UTP/MT-RJ/VF-45 ) in the rack by
lining up the holes in the brackets with the appropriate holes on
the rack. Secure the Switch to the rack with a screwdriver and the
rack-mounting screws.

Standard 19-inch Rack
Note: For proper ventilation, allow about at least 4 inches (10 cm) of
clearance on the front and 3.4 inches ( 8 cm ) on the back of the
Switch. This is especially important for enclosed rack installation.
3.3ConnectingtotheSwitch
The Console port is a female DB-9 connector that enables a
connection to a PC or terminal for monitoring and configuring the
SMC-EZ1026DT V.2 Switch. Use the supplied RS-232 cable with a
male DB-9 connector to connect a terminal or PC to the Console
port.
The Console configuration (out of band) allow you to set your Switch
to enable a user at a remote console terminal to communicate with
the SMC-EZ1026DT V.2 Switch as if the console terminal were
directly connected to it.

3.4 Login in the Console Interface
When the connection between Switch and PC is finished, turn on the
PC and run a terminal emulation program or Hyper Terminal and
configure its communication parameters to match the following
default characteristics of the console port:
Baud Rate: 19200 bps
Data Bits: 8
Parity: none
Stop Bit: 1
Control flow: None

Pick up the selection you would like to change the status and to toggle
the Enable / Disable field and type in appropriate value in the Aging Time
and Priority field.
Figure 3-8. The Device Configuration Setup menu
•Broadcast Storm Prevention can be set to 6% or 20% beside Disable.
The percentage indicates the allowance against the capacity. When its
disable there will be no limitation on the incoming rate of broadcast /
traffic, otherwise limitation on those traffics will be set to the percentage

accordingly.
•There are two different mode of VLAN supported in this system – Port
Base VLAN, MTU/MDU. The choice you made here will ultimately decide
the VLAN mode and function for entire system (the configuration of the
other two VLAN mode will have no effect to the system behavior).
B. Port Configuration
Figure 3-9. The Port Configuration Menu
The Ports (24+2) of the system are divided and displayed in three
separated pages. Use PREV PAGE, NEXT PAGE to list desired port
range and select the port.
In the port configuration screen you can configure the common
characteristics such as speed negotiation, and flow control, as well
as the following special features provided with the system:
•Bandwidth provisioning - 8 levels of speed control facilitate the
provisioning control for access provider.

C. Port Statistics
Figure 3-10. The Port Statistics Menu
You can view the statistics information display in this screen regarding a
certain port by entering the port number. You can also refresh or reset
the counter as you wish.
D. Port Based VLAN Configuration
Figure 3-11. The Port Based VLAN Configuration
Assigning physical ports within workgroup is simple, and is a common
method of defining a virtual workgroup – VLAN. It delivers the benefit of

SMC-EZ1026DT V.2

broadcast control and simplifies configuration for the network manager.
One advantage of the Port-Based VLAN is its simplicity and easy to
configure, however, limited security is its drawback – anyone can plug
into the port and gain access to the VLAN.
Port Based VLAN Setup

Select the VLAN entry to create, modifies, or deletes the VLAN group.
Use <Space Bar> to check (join) or quit port(s) to the VLAN group.
E. Trunk Configuration

Multiple links between switches can be grouped (trunk) to work as one
virtual, aggregate link. You can create 4 trunks at a time; each trunk can
hold up to 8 ports - only ports of the same speed can belong to a single
trunk.
