FCC Warning
This equipment has been tested and found to comply with the
regulations for a Class A digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with this user’s guide, may cause harmful interference to
radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference, in which case the user will
be required to correct the interference at his or her own expense.
CE Mark Warning
This is a Class A product. In a domestic environment, this product
may cause radio interference, in which case the user may be required
to take adequate measures.
VCCI Warning
This is a product of VCCI Class A Compliance.

UL Warning
a) Elevated Operating Ambient Temperature- If installed in a closed
or multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the manufacturer's maximum rated
ambient temperature (Tmra).
b) Reduced Air Flow- Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of the
equipment is not compromised.
c) Mechanical Loading- mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
d) Circuit Overloading- Consideration should be given to the
connection of the equipment to the supply circuit and the effect that
overloading of circuits might have on over current protection and
supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
e) Reliable Earthing- Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit (e.g.,
use of power strips).

INTRODUCTION
This chapter describes the features of the 48+4G-Port
10/100/1000Mbps Gigabit Ethernet Web Smart Switch and some
background information about Ethernet/Fast Ethernet/Gigabit Ethernet
switching technology.
Switching Technology
Another approach to pushing beyond the limits of Ethernet technology
is the development of switching technology. A switch bridges
Ethernet packets at the MAC address level of the Ethernet protocol
transmitting among connected Ethernet or Fast Ethernet LAN
segments.
Switching is a cost-effective way of increasing the total network
capacity available to users on a local area network. A switch increases
capacity and decreases network loading by dividing a local area
network into different segments, which don’t compete with each other
for network transmission capacity.
The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with any other
segments, automatically forwards traffic that needs to go from one
segment to another. By doing this the total network capacity is
multiplied, while still maintaining the same network cabling and
adapter cards.
Switching LAN technology is a marked improvement over the
previous generation of network bridges, which were characterized by
higher latencies. Routers have also been used to segment local area
networks, but the cost of a router, the setup and maintenance required
make routers relatively impractical. Today switches are an ideal
solution to most kinds of local area network congestion problems.

VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by their
physical location and can communicate as if a common broadcast
domain, a LAN. The primary utility of using VLAN is to reduce
latency and need for routers, using faster switching instead. Other
VLAN utility includes:
Security
Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network because data will be switched
to only those confidential users within the VLAN.
Cost Reduction
VLANs can be used to create multiple broadcast domains, thus
eliminating the need of expensive routers.
Port-based (or port-group) VLAN is the common method of
implementing a VLAN, and is the one supplied in the Switch.
Limitations
TEG-2248WS has 2 port groups for VLAN settings which are
mutually exclusive. Ports from 1 through 24 are in one group and have
no limitations on the VLAN that can be set up within the group. Ports
from 25 to 52 are in the second group. Ports from group 1 cannot
belong to a VLAN with ports from group 2.

UNPACKING AND INSTALLATION
This chapter provides unpacking and installation information for the
Switch.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks its
contents. The carton should contain the following items:
 One 48+4G-Port 10/100/1000Mbps Gigabit Ethernet Web
Smart Switch
 One AC power cord, suitable for your area’s electrical power
connections
 Four rubber feet to be used for shock cushioning
 Screws and two mounting brackets
 CD-Rom with Web Management Utility and User’s Guide
If any item is found missing or damaged, please contact your local
reseller for replacement.
Installation
The site where you install the hub stack may greatly affect its
performance. When installing, consider the following pointers:
Install the Switch in a fairly cool and dry place. See Technical
Specifications for the acceptable temperature and humidity operating
ranges.
Install the Switch in a site free from strong electromagnetic field
generators (such as motors), vibration, dust, and direct exposure to
sunlight.
