The NETGEAR™ Model DS309 Dual Speed Hub is a network hub that enables users to mix and
match 10 and 100 megabit per second (Mbps) devices on the same network. This capability
eliminates the high cost and complexity of separate network equipment for 10 and 100 Mbps
users. The Model DS309 hub is ideal for small networks in transition from 10 to 100 Mbps and for
linking networks operating at different speeds.
The hub connects PCs to share printers, files, Internet access, and e-mail communications. Each
network port coordinates with the connected PC to run at 10 or 100 Mbps, making network
configuration and upgrade effortless. In addition, the 10 and 100 Mbps network segments are
internally bridged to form one network, providing full connectivity among all users.
Features
Features
The Model DS309 Dual Speed Hub has the following key features:
• Nine autosensing, dual-speed (10/100 Mbps) ports
– Internally bridged 10 and 100 Mbps network segments to form one network, providing full
connectivity among all users
– One switched port that enables the Model DS309 hub to cascade to other 100 Mbps hubs,
bypassing 100BASE-TX limitations
• Ability of each port on the hub to independently detect the speed of the attached device and
to automatically connect at the appropriate speed
• IEEE 802.3u standard compliance for interoperation with all 100BASE-TX Fast Ethernet
(100 Mbps) products and 802.3i standard compliance for interoperation with all 10BASE-T
Ethernet products
• Easy Plug-and-Play installation with no software to configure, saving time and minimizing
the potential for configuration errors
• Chassis equipped with:
– Status indicators on both the front and rear panels
– Built-in vista LEDs on each network port clearly indicating individual port status
– Additional LEDs providing network traffic status for the hub
– Two LED bar graphs providing online status of network utilization and alerting you to
potential network overload
– Normal/Uplink push button for simplifying network extension
• Design planned for home and small office use
– Network ports located on the back of the hub so that cables are kept away from the desktop
– Compact design to fit into small offices
– Compliance with the Class B EMI standard so the hub does not interfere with your home
appliances
• 5-year warranty on hub unit (1-year warranty on power supply)
