1. INTRODUCTION
1.1 Product Briefs
The switch is a un-management layer 2 10/100Mbps switch; it provide dedicated 10,
100 ,1000Mbps Ethernet bandwidth on each port. The ports will automatically detect the
speed, duplex and MDI/MDIX status of the device it is connecting to, and adjust these
settings accordingly. The Switch ports can be used to network computers, printers, servers,
routers, other switches or any device equipped with an Ethernet port. For best performance,
use Category 5 or better Ethernet cabling.
This stand-alone Switch is very easy to set up, there is no network management required. Just
power on the Switch and connect the cables. Keep in mind however that the standard rules of
Ethernet regarding cable length apply to this and all Ethernet devices. The length of an
Ethernet cable from one device to another cannot exceed 100 meters (or 300 feet).
1.2 Product Features
The Switches do not require any management. All Switches are designed for easy installation,
flexibility and high performance. Connect devices to the Switch as the scale and volume of
network traffic increases.
16 10/100/1000Mbps Gigabit ports
Auto-Negotiation for 10/100/1000Mbps and duplex mode
Auto-MDI/MDIX for each port
Supports Full/Half-duplex transfer mode for 10 and 100Mbps
Full wire speed reception and transmission
Store-and-Forward Switching method
Supports 8K absolute MAC addresses
16-Port Switch Supports 340KB RAM for data buffering
IEEE 802.3x flow control for Full-duplex
Back pressure flow control for Half-duplex
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure,
format, and support for CSMA/CD protocol, full duplex, flow control, and management
objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet
4
and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps
and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade
without wasting a company’s existing investment in hardware, software and trained
personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to coping
with the network bottlenecks that frequently develop as computers and their bus speeds get
faster and more users use applications that generate more traffic. Upgrading key components,
such as your backbone and servers to Gigabit Ethernet can greatly improve network response
times as well as significantly speed up the traffic between your subnets.
