INTRODUCTION
This chapter describes the features of the DSS-16+ and some background
information about Ethernet/Fast Ethernet switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop
computing applications are fueling the need for high performance networks.
A number of high-speed LAN technologies have been proposed to provide
greater bandwidth and improve client/server response times. Among them,
100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution
from the current 10BASE-T technology. The non-disruptive and smooth
evolution nature, and the dominating potential market base, virtually
guarantee cost-effective and high-performance Fast Ethernet solutions in the
years to come.
100Mbps Fast Ethernet is a new standard specified by the IEEE 802.3 LAN
committee. It is an extension of the 10Mbps Ethernet standard with the
ability to transmit and receive data at 100Mbps, while maintaining the
CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible
with all other 10Mbps Ethernet environments, it provides a straightforward
upgrade and takes advantage of the existing investment in hardware,
software, and personnel training.

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 ano ther.
By doing this the total network capacity is multiplied, while still maintaining
the same network cabling and adapter cards.
For Fast Ethernet networks, a switch is an effective way of eliminating
problems of chaining hubs beyond the “two-repeater limit.” A switch can be
used to split parts of the network into different collision domains, making it
possible to expand your Fast Ethernet network beyond the 205-meter network
diameter limit for 100BASE-TX networks. Switches supporting both
traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for
bridging between the existing 10Mbps networks and the new 100Mbps
networks.
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
3
network congestion problems.
Features
The DSS-16+ is designed for easy installation and high performance in an
environment where traffic on the network and the number of users increase
continuously.

UNPACKING AND SETUP
This chapter provides unpacking and set u p info rmation for the DSS-16+.
Unpacking
Open the shipping carton for the Switch and carefully unpack its contents.
The carton should contain the following items:
One DSS-16+ 16-port 10/100Mbps Fast Ethernet 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
This User’s Guide
If any item is found missing or damaged, please contact your local reseller
for replacement.
Setup
Please consider the following when setting up the Switch:
1. The surface must support at least 5 kg.
2. The power outlet should be within 1.42 meters (6 feet) of the device.
3. Visually inspect the power cord and see that it is secured fully to the AC
power connector.
4. Make sure that there is proper heat dissipation from and adequate
5
ventilation around the Switch. Do not place heavy objects on the Switch.
Desktop Installation
When installing the Switch on a desktop, the rubber feet
included with the device must be attached first. Attach these
cushioning feet on the bottom at each corner of the device.
Allow enough ventilation space between the device and the
objects around it.

Rack Mounting
The DSS-16+ can be mounted in an EIA standard-size, 19-inch rack, which
can be placed in a wiring closet with other equipment. Attach the mounting
brackets at the switch’s front panel (one on each side), and secure them with
the provided screws.

Then, use screws provided with the equipment rack to mount each switch in
the rack.

IDENTIFYING EXTERNAL COMPONENTS
This section identifies all the major external components of the DSS-16+.
The figure below shows the front panels of the DSS-16+.
16-port 10/100Mbps Fast Ethernet Switch
1. LED Indicator Panel
Refer to the detailed information about each of the DSS-16+’s LED
indicators.
Power
This indicator lights green when the switch is receiving power; otherwise, it
is off.
Link / Act (Link/Activity)
This indicator lights on when the port is connected to a Fast Ethernet or
Ethernet device; if the light is blinking, it indicates that data is being
transmitted or received.
8
FDX / Col (Full-duplex/Collision)
This LED indicator lights green when a respective port is in full duplex
(FDX) operation mode. Otherwise, it is blinking when collisions are
occurring on the respective port in half duplex operation mode.
100Mbps
This LED indicator lights green when the port is connected to a 100Mbps
Fast Ethernet station. Otherwise, the LED is off when the port is connected to
a 10Mbps Ethernet device.
2. Twisted-Pair Ports
These ports support
modes of full or half duplex. They
auto-negotiation for speeds of 10M or 100M, and operation
also support Auto-MDI/MDIX crossover
detection function for giving a true “plug and play” capability. Just plug the
network cable directly into the Switch. It makes no difference if the end node
is a NIC (Network Interface Card,) a switch, or a hub.
