General Description
The device is a powerful, high-performance 10/100/1000Mbps Fast Ethernet and
Gigabit switch, with all 8 ports capable of 10/100/1000Mbps auto-negotiation
operation (NWay), which means the switch could automatically negotiate with the
connected partners on the network speed and duplex mode. Moreover, the
10/100/1000Mbps auto-sensing ability provides an easy way to migrate 10Mbps to
100Mbps or 1000Mbps networks with no pain. Compared to the shared 10Mbps,
100Mbps or 1000Mbps networks, the switch delivers a dedicated 10/100/1000Mbps
connection to every attached client with no bandwidth congestion issue.
All Gigabit ports support auto-negotiation operation, auto MDI-X crossover function
and Full-Duplex mode. They are ideal for micro-segmenting large networks into
smaller, connected subnets for improved performance, enabling the bandwidth
demanding multimedia and imaging applications. The device also provides the fat
pipe to the servers or backbone connection for boosting the total system
The built-in smart capabilities, VLAN, Port-Trunking, Port Config, Port Priority, Port
snooping and 4-level IP priority, empowered system administrator to monitor and
control the network easily.
Store-and-forward switching mode promises the low latency plus eliminates all the
network errors, including runt and CRC error packets. To work under full-duplex
mode, transmission and reception of the frames can occur simultaneously without
causing collisions as well as double the network bandwidth.
The switch is plug-n-play without any software to configure and also fully compliant
with all kinds of network protocols. Moreover, the rich diagnostic LEDs on the
front-panel can provide the operating status of individual port and whole system.

close to a power outlet. Plug in all network cables and the power cord, then the
system is ready.
Before installing the switch, you must ensure:
1. It is accessible and cables can be connected easily
2. Cabling is away from:
*Sources of electrical noise such as radios, transmitters and broadband
*Power lines and fluorescent lighting fixtures.
3. Keep water or moisture off
4. Airflow around the unit and through the vents in the side of the case is great
for heat radiation (company recommend that you provide a minimum of 25
mm clearance)
To prolong the operational life of your units:
1. Never stack unit more than eight sets high if freestanding
2. Do not place objects on top of any unit or stack
3. Do not obstruct any vents at the sides of the case
Rack-Mount Installation
The switch may standalone, or may be mounted in a standard 19-inch
equipment rack. Rack mounting produces an orderly installation when you
have a number of related network devices. The switch is supplied with two
mounting brackets and screws (Optional for 11-inch model). These are used
for rack mounting the unit.

Connect each station to the switch by a category 5 twisted-pair cable
(straight or cross-over cable). Plug one RJ-45 connector into a
front-panel port of the switch, and plug the other RJ-45 connector into
the station’s network adapter.
Switch-to-Switch Connections
In making a switch-to-switch connection, you could use any port to
connect another switch with straight or crossover cable.
As all ports support auto MDI/MDI-X function, the connection is
independent of cable type and allows using a straight cable to make a
switch-to-switch connection.
The switch supports 2 groups port-trunk; port-1 and port-2 belong to
“Trunk A”, port-7 and port-8 belong to “Trunk B”. As each port-trunk
group provides 4 Gigabit bandwidth on Full Duplex mode, it is ideal
for establishing switch-to-switch connection.

Switch Operation
MAC Address Table and Learning
The switch is implemented with a MAC address table, which is composed of many
entries. Each entry is used to store the address information of network nodes on the
network, including MAC address, port ID, etc. The information is the most important
base to do packet filtering and forwarding.
When one packet comes in from any port, the switch will learn the source address,
port ID, and the other related information in address table. Therefore, the content of
the MAC table will update dynamically.
Filtering and Forwarding
When one packet comes in from any port of the switch, it will check the destination
address besides the source address learning. The switch will look up the address
table for the destination address. If not found, this packet will be forwarded to all the
other ports except the port where the packet comes in. If found, and the destination
address is located at different port from this packet comes in, the packet will be
forwarded to the port where this destination address is located according to the
information of address table. But, if the destination address is located at the same
port as this packet comes in, this packet will be filtered.
Store and Forward
Store-and-forward is one kind of packet-forwarding methodology. As a
store-and-forward switch, it will store the complete packet in the internal buffer and
do the complete error checking before transmitting to the network. Therefore, no
error packets will disturb the network. It is the best choice when a network needs
efficiency and stability.
