The NETGEAR Model DS508 Dual Speed Stackable Hub and Model
DS516 Dual Speed Stackable Hub are network hubs that enable users
to mix and match 10 and 100 megabits per second (Mbps) devices on
the same network. This mix of devices eliminates the high cost and
complexity of separate network equipment for 10 and 100 Mbps users.
The Model DS508 and Model DS516 hubs are ideal for small networks
in transition from 10 to 100 Mbps. Up to eight hubs can be stacked so
that the network can expand to serve as many as 128 users.
The Model DS508 and Model DS516 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.
The Model DS508 and Model DS516 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 network as required by using the provided cascade
cables (You can stack up to eight hubs for a total of 128 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
•
Fault redundancy (If the unit with the operating bridge fails in a
stack of hubs, the next unit will take over the function, thus
ensuring connectivity among 10 and 100 Mbps users.)
•
Stackable chassis equipped with:
–
8 or 16 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
–
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
•
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)

The Model DS508 and Model DS516 hubs can be used for connecting
users to shared network resources such as servers, printers, and routers.
Both 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 Model
DS508 and Model DS516 hubs in a mixed 10/100 Mbps environment.
