SWITCH
ARCHITECTURE
The switch performs a wire-speed, non-blocking switching fabric.
This allows wire-speed transport of multiple packets at low
latency on all ports simultaneously. The switch also features
full-duplex capability on all ports, which effectively doubles the
bandwidth of each connection.
This switch uses store-and-forward technology to ensure
maximum data integrity. With this technology, the entire packet
must be received into a buffer and checked for validity before
being forwarded. This prevents errors from being
propagated throughout the network.
NETWORK
MANAGEMENT
OPTIONS
The switch can also be managed over the network with a
web browser or Telnet application. The switch includes a built-in
network management agent that allows it to be
managed in-band using SNMP or RMON (Groups 1, 2, 3, 9)
protocols. It also has an RJ45 console port connector on the
front panel for out-of-band management. A PC may
be connected to this port for configuration and monitoring
out-of-band via a null-modem serial cable. (See Appendix B for
wiring options.)
NOTE: For a detailed description of the management features,
refer to the User’s manual.

DESCRIPTION OF
HARDWARE
1000BASE-T
PORTS

RJ-45 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
SM4T4DPA supports the Small Form Factor Pluggable (SFP) transceiver.

NETWORK PLANNING
INTRODUCTION
TO SWITCHING
A network switch allows simultaneous transmission of multiple
packets; it can partition a network more efficiently than bridges
or routers. Therefore the switch has been recognized as one of
the most important device for today’s networking technology.
When performance bottlenecks are caused by congestion at the
network access point such as file server, the device can
be connected directly to a switched port. And, by using
full-duplex mode, the bandwidth of the dedicated segment can
be doubled to maximize throughput.
When networks are based on repeater (hub) technology, the
distance between end stations is limited by a maximum
hop count. However, a switch can subdividing the network into
smaller and more manageable segments, and linking them to
the larger network than it turns the hop count back to zero
and removes the limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet,
or Gigabit Ethernet network to significantly increase bandwidth
while using conventional cabling and network cards.
APPLICATION
EXAMPLES
The Switch implements 4 Gigabit Ethernet TP ports and 4 slots
for the removable SFP module which supports comprehensive
types of fiber connection, such as LC and BiDi-LC modules. It is
not only designed to segment your network, but also to provide
a wide range of options in setting up network connections. Some
typical applications are described below.
The switch is suitable for the following applications.
 Remote site application is used in Enterprise or SMB
 Peer-to-peer application is used in two remote offices
 Office network
 High Performance Requirement environment
 Advance Security for network safety application
 Suitable for data/ voice and video conference application

INSTALLING THE
SWITCH
SELECTING A
SITE
The Switch can be mounted in a standard 19-inch equipment
rack (Via Optional Rack mount Kit) or on a flat surface. Be
sure to follow the guidelines below when choosing a location.
◆ The site should:
 Be at the center of all the devices you want to link
and near a power outlet.
 Be able to maintain its temperature within 0 to 40°C
(32 to 104 °F) and its humidity within 10% to 90%,
non-condensing.
 Be accessible for installing, cabling and maintaining
the devices.
 Allow the status LEDs to be clearly visible.
◆ Make sure the twisted-pair Ethernet cable is always
routed away from power lines, radios, transmitters or any
other electrical interference.
◆ Make sure that SM4T4DPA Switch is connected to a separate
grounded power outlet that provides 100 to 240 VAC, 50 to
60 Hz.
ETHERNET
CABLING
To ensure proper operation when installing the switch into a
network, make sure that the current cables are suitable for
100BASE-TX or 1000BASE-T operation. Check the
following criteria against the current installation of your
network:
◆ Cable type: Unshielded twisted pair (UTP) or
shielded twisted pair (STP) cable with RJ-45 connectors;
Category 5 or Category 5e with maximum length of 100
meters is recommend 100BASE-TX, and Category 5e or 6
with maximum length of 100 meters is recommend for
1000BASE-T.
◆ Protection from radio frequency interference emissions.
◆ Electrical surge suppression.
◆ Separation of electrical wires and data based network
wiring.
◆ Safe connections with no damaged cables, connectors or
shields.

rack assembly is not overloaded.
 Grounding: Rack-mounted equipment should be properly
grounded.
TO Rack-mount Devices:
Step1. Attach the brackets to the device using the screws provided in the Mounting
Accessory.
Figure 9: Attaching the Brackets
Step2. Mount the device in the rack (Via Optional Rack-Mount kit), using four
rack-mounting screws (not provided). Be sure to secure the lower
rack-mounting screws first to prevent the brackets being bent by the weight of
the switch.
Figure 10: Installing the switch in a Rack
Step3. If installing a single switch only, turn to “Connection to a Power Source” at the
end of this chapter.

DESKTOP OR SHELF MOUNTING:
Step1. Attach the four adhesive rubber feet to the bottom of the first switch.
Figure 11: Attaching the Adhesive Rubber Feet
Step2. Set the device on a flat surface near an AC power source, making sure there are
at least two inches of space on all sides for proper air flow.
Step3. If installing a single switch only, go to “Connecting to a Power Source” at the
end of this Chapter.
Step4. If installing multiple switches, attach four adhesive feet to each one. Place each
device squarely on top of the one below, in any order.
INSTALLING AN
OPTIONAL SFP
TRANSCEIVER
You can install or remove a mini-GBIC SFP from a mini-GBIC slot
without having to power off the switch. Use only Manufacture
mini-GBIC.
NOTE:
 The SFP ports operate only at full duplex. Half duplex
operation is not supported.
 Ensure the network cable is NOT connected when you
install or remove a SFP.

TO Install a SFP transceiver, do the following:
Step1. Consider network and cabling requirements to select an appropriate SFP
transceiver type.
Step2. 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.
Step3. Slide the SFP transceiver into the slot until it clicks into place.
NOTE: SFP transceivers are not provided in the switch package.
CONNECTING
TO A POWER
SOURCE
You can plug or remove power cord from AC power socket , to
switch the power on and off .
