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.

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.

Front-Panel LEDs The Model DS508, DS516, and DS524 hubs provide front-panel LEDs for monitoring individual ports and hub status. The following table describes the front-panel LEDs and their functions. Label Color Activity Description Power Green On Power is supplied to the hub. 10 Mbps Amber On Data collision is occurring on the 10 Mbps network segment (some collisions are normal). 100 Mbps Amber On Data collision is occurring on the 100 Mbps network segment (some collisions are normal).

Rack requirements Standard 19-inch (48.26 cm) EIA equipment rack, with supplied mounting bracket hardware; 1.0 EIA rack-mount spaces needed for each hub. Wiring hardware Wiring hardware, such as punchdown blocks or patch panels, should be complete before installing the hub.
Installation Procedures Install the Hub Install the Hub on a Flat Surface If installing the hub on a flat surface such as a tabletop, make sure the bottom of the chassis is clean and dry and allow at least 2 inches of space on all sides of the hub to ensure proper ventilation. 1. 2. 3. Install the self-adhesive footpads on the bottom of the hub. Set the hub on a table or shelf so that it has at least 2 inches (5 cm) of space on all sides.
Build a Larger Network Cascade up to Eight Hubs to Build a Larger Network As many as eight Model DS508, Model DS516, or Model DS524 hubs can be cascaded for up to a maximum of 192 ports in a single repeater (or collision) domain. Any device connected to one of the 192 ports at either 10 or 100 Mbps can connect through the network to any other device attached to the cascade stack.
Connect a PC to the Hub 5 Data Collisi on Power Power Data Collisi Link on RX 17 Link 12 RX Norma l/Uplin k 24 8094FA Caution: 100 Mbps operation requires the use of Category 5 UTP wiring with 100 Mbps certified connectors. NETGEAR highly recommends using Category 5 cable so your network can operate at either 10 or 100 Mbps.
Cable & Connector Information Twisted Pair Cables For two devices to communicate, the transmitter of each device must be connected to the receiver of the other device. The crossover function is usually implemented internally as part of the circuitry in the device. Most repeaters and switch ports are media-dependent interfaces with crossover ports, referred to as MDI-X or Normal ports. Computers and workstation adapter cards are usually media-dependent interface ports, referred to as MDI or Uplink ports.
