INTRODUCTION
This chapter describes the features of the Switch 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 bridge 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
3
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.
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
network congestion problems.
Features
The Switch was designed for easy installation and high performance in an
environment where traffic on the network and the number of user increase
continuously.
The Switch with its small, compact size was specifically designed for small
to middle workgroups. This Switch can be installed where space is limited;
moreover, they provide immediate access to a rapidly growing network
through a wide range of user-reliable functions.

The Switch is ideal for deployment with multiple high-speed servers for
shared bandwidth 10Mbps or 100Mbps workgroups. With the highest
bandwidth 200Mbps (100Mbps full-duplex mode), any port can provide
workstations with a congestion-free data pipe for simultaneous access to the
server.
The Switch is expandable by cascading two or more switches together. As
all ports support 200Mbps, the Switch can be cascaded from any port and to
any number of switches.
The Switch is a perfect choice for site planning to upgrade to Fast Ethernet in
the future. Ethernet workgroups can connect to the Switch now, and change
adapters and hubs anytime later without needing to change the Switches or
reconfigure the network.
The Switch combine dynamic memory allocation with store-and-forward
switching to ensure that the buffer is effectively allocated for each port, while
controlling the data flow between the transmit and receive nodes to guarantee
against all possible packet loss.
The Switch is a 10/100 Fast Ethernet Switch that offers solutions in
accelerating small Ethernet workgroup bandwidth. Other key features are:
Supports one 100BASE-FX multimode fiber port for long distance
connection, up to 2km in full-duplex mode.
Supports seven 10/100Mbps NWay Ethernet RJ-45 MDI-X ports.
Store and forward switching scheme capability. As the result of
complete frame checking and error frame filtering, this scheme
prevents error packages from transmitting among segments.
NWay Auto-negotiation for RJ-45 ports (port-1 ~ port-7). This allows
for auto-sensing of speed (10/100Mbps) thereby providing you with
automatic and flexible solutions in your network connections.
Flow control for any port. The Switch provides back-pressure flow
control method for half duplex operation and IEEE 802.3x pause
frame-based flow control method for full duplex operation.
Data forwarding rate per port is at wire-speed for 100Mbps and
10Mbps speed.
Data filtering rate eliminates all error packets, runts, etc., per port at
5
wire-speed for 100Mbps and 10Mbps speed.
1K MAC address entries table per device for the Switch.
KB RAM buffer per device for the Switch.

UNPACKING AND SETUP
This chapter provides unpacking and setup information for the Switches.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks its contents.
The carton should contain the following items:
One 8-Port 10/100Mbps NWay Ethernet Switch
One external power adapter
This User’s Guide
If any item is found missing or damaged, please contact your local reseller
for replacement.
Setup
The setup of the Switch can be performed using the following steps:
The surface must support at least 1 Kg for the Switch.
The power outlet should be within 1.77 meters of the Switch.
Visually inspect the DC power jack and make sure that it is fully
secured to the power adapter.
Make sure that there is proper heat dissipation from and adequate
ventilation around the Switch. Do not place heavy objects on the
Switch.

IDENTIFYING EXTERNAL COMPONENTS
This section identifies all the major external components of the hub. Both the
front and rear panels are shown followed by a description of each panel
feature. The indicator panel is described in detail in the next chapter.
Front Panel
The figure below shows the front panels of the switch.
LED Indicator Panel
Power Indicator (Power)
This LED indicator lights green when the switch is receiving power,
otherwise, it is off.
Full-Duplex/Collision (FDX/Col)
This LED indicator lights green when a respective port is in full duplex (FDX)
mode. Otherwise, it is blinking when collisions are occurring on the
respective port.
Link/Activity (100M LINK/ACT(green), 10M LINK/ACT(amber))
This LED indicator lights green when the port is connected to a 100Mbps
Fast Ethernet station, if the indicator blinking green will be transmission or
received data on the 100Mbps network. Otherwise, if the indicator lights
amber when the port is connected to a 10Mbps Ethernet station, if the
indicator blinking amber will be transmission or received data on the 10Mbps
network.
8
Rear Panel
DC Power Jack: Power is supplied through an external AC power adapter.
Since the switch does not include a power switch, plugging its power adapter
into a power outlet will immediately power it on.
Auto-MDI-X Function ports: Use these jacks (port-1 ~ port-7) to connect
stations to the hub. An Auto-MDI-X function will automatically detect if a
crossover is required and make the swap of Tx pair and Rx pair internally.
With this function, straight-through cable can be used for any connection.
MDI to MDI-X connection rule is not necessary anymore. In the switches, all
TP ports are equipped with this function. You can use just straight-through
type of cables for all your connections.
100BASE-FX Fiber Port: The Fiber port supports 100BASE-FX
62.5/1252m multimode fiber. The TX port has to link to others end RX port,
and the RX port has to link to others end TX port.
Duplex Mode Switch: The switch is to select the operation mode either to
run in full or half duplex mode for 100BASE-FX. When turning the switch to
FDX, the fiber port will run at full duplex or turn to HDX, the fiber will run
at half duplex.
