NETGEAR DS508 User Manual
Start Here
The NETGEAR Model DS508, Model DS516, and Model DS524 Dual Speed Stackable Hubs are
network hubs that enable users to mix and match 10 and 100 megabit per second (Mbps) devices
on the same network. This mix of devices eliminates the high cost and complexity of separate
network equipment for 10/100 Mbps users. All three hub models are ideal for small networks in
transition from 10 Mbps to 100 Mbps operation. Up to eight hubs can be stacked so that the
network can expand to serve as many as 192 users.
The Model DS508, Model DS516, and Model DS524 hubs connect 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
The Model DS508, Model DS516, and Model DS524 hubs have the following key features:
• Per port, autosensing, dual-speed (10/100 Mbps) operation
• 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
• Stackable architecture, allowing you to start with as few as 8 ports and expand the netw ork as
required by using the provided cascade cables (You can stack up to eight hubs for a total of
192 10 or 100 Mbps ports.)
• Easy Plug-and-Play installation with no software to configure, saving time and minimizing
the potential for configuration errors
• Ability of each port on the hub to independently detect the speed of the attached device and to
automatically connect at the appropriate speed
• Internally bridged 10 and 100 Mbps network segments to form one network, providing full
connectivity among all users
• Built-in redundancy through the 10/100 Mbps bridge within each hub
If the unit with the operating bridge fails in a stack of hubs, the next bridge will take over the
function, thus ensuring connectivity among 10 Mbps users and 100 Mbps users. Furthermore,
if one hub in a stack fails, the remaining hubs and ports continue to be fully functional.
• Stackable chassis equipped with:
– 8, 16, or 24 10BASE-T or 100BASE-TX ports providing fast information exchange,
resource sharing, and client or peer-to-peer communication using simple Category 5
UTP wiring
– Vista network ports with built-in LEDs, 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 using straight-through
cables
• Compact (13 by 8 by 1 7/8 inches) design that enables tabletop or rack installation
• Internal 100 to 240 V AC power supply
• Dual cooling fans (side and rear)
• 5-year warranty on hub unit (1-year warranty on power supply)

Typical Applications
The Model DS508, Model DS516, and Model DS524 hubs can be used for connecting users to
shared network resources such as servers, printers, and routers. All models allow for easy
migration from 10 Mbps to 100 Mbps operation. Users connected at 10 Mbps can coexist with
power users connected at 100 Mbps; both types of users can take advantage of shared resources
connected at the higher transmission speed. The following illustration shows some typical
applications of the three hub models in a mixed 10/100 Mbps environment.
