SMCGS803
EZ Switch
TM
10/100/1000 Mbps
8-Port Gigabit Ethernet Switch
Product Overview
The EZ Switch 10/100/1000 SMCGS803 switch provides the new loopback detection features that improves the
network environment and reduces network maintenance costs. The SMCGS803 switch uses the internal power
design, with up to 10 times the speed of 100Mbps networks, the switch reduces transfer times of large data files
and boosts bandwidth-intensive applications, thereby significantly enhancing overall network performance. Jumbo
frame support enables more efficient data transfers with data packets up to 9K Bytes in size. The switch is easy to
install and an ideal solution for network migration with its 10/100/1000 Mbps Auto MDI/MDIX ports. Not only are
ports triple-speed, all ports can be connected to either a workstation or another switch, without the need for
crossover cables. Supporting non-blocking wire-speed throughput, the switch is built to handle the growing
performance needs of bandwidth-hungry applications in today's networks.
EEE Support
The switch supports the IEEE 802.3az Energy-Efficient
Ethernet (EEE) feature to save power consumption.
Fan-less Design
The switch supports a fan-less design, providing a silent
operating environment.
IEEE 802.1p QoS
When the switch receives a frame tagged with an
802.1p priority, it places it into the appropriate priority
output queue. Priority queuing is needed in
implementations where time-sensitive data, such as
voice and video, are streamed across the network.
Key Features and Benefits
Loopback Detection
When a loop occurs, the switch indicates the port
that has the loop issue with the port LED.
Support for Jumbo Packets
Support for Jumbo packets of up to 9K Bytes in size.
Auto MDI/MDI-X on each port
Support for Auto MDI/MDI-X means that no
crossover cables are required. Straight-through
cables can be used for all connections.
Application Diagram
The SMCGS803 provides a loopback detection function. When a loop occurs, the Loop LED turns on and the port LED
indicates the port with the loop issue.

Loop Detect
When a loop occurs, the port LED flashes twice per second to indicate the port with the
loop issue.
