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 network 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) Model DS508/DS516/DS524 Dual Speed Stackable Hub Installation Guide Package Contents Model DS508, Model DS516, or Model DS524 hub (Model DS516 shown) 5 Data Coll ision Power Power Data Coll ision Link RX 17 Link RX 12 Normal/U 24 plink Rubber footpads Power cord Rack mount kit Installation guide, Warranty & Owner Registration Card Cascade cable 8672FA Verify that the package contains the following items: · · · · · · Model DS508, Model DS516, or Model DS524 hub Rack mount kit Cascade cable Rubber footpads for tabletop installation Warranty & Owner Registration Card Power cord Caution: Use the appropriate power cord as required by your national electrical codes and ordinances. Model DS508/DS516/DS524 Dual Speed Stackable Hub Installation Guide 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.

The following table describes the front-panel LEDs and their functions. Label Power Collision 10 Mbps 100 Mbps Utilization% 10 Mbps Green Blinking Indicates the amount of data traffic on the 10 Mbps segment. (If a 100 Mbps user is sending data to a 10 Mbps user, 10 Mbps utilization will be high.) Indicates the amount of data traffic on the 100 Mbps segment. A link is established successfully between the hub and the PC. No data link is established and/or the cable is not connected, is defective, or is the wrong type or the connected network card is not properly set up. There is incoming data on the port. Amber Amber On On Data collision is occurring on the 10 Mbps network segment (some collisions are normal). Data collision is occurring on the 100 Mbps network segment (some collisions are normal). Color Green Activity Description On Power is supplied to the hub. 100 Mbps Green Blinking On Off 10M or 100M Green Link/Receive (built into each vista RJ-45 network port) Blinking Vista RJ-45 Network Ports with Built-In LEDs The front panel of the Model DS508 hub provides 8 vista RJ-45 network ports, the Model DS516 hub provides 16 vista RJ-45 network ports, and the Model DS524 provides 24 vista RJ-45 network ports. These standard RJ-45 connectors accept two-pair or four-pair Category 5 unshielded twisted-pair (UTP) copper wiring (only two pairs are used). The RJ-45 connector uses an 8-pin interface. Two LEDs are positioned at the top corners of each RJ-45 connector. The left indicator is the 100 Mbps Link/Receive LED, and the right indicator is the 10 Mbps Link/Receive LED.

The Terminator LED indicates whether or not the built-in terminator in that hub is active (the built-in terminator eliminates the need for an external terminator). The 10/100 Mbps Bridge LED indicates which hub has the active bridge. Site Preparation Before you begin installing the hubs, prepare the installation site.

Model DS508/DS516/DS524 Dual Speed Stackable Hub Installation Guide 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. Connect the power cord(s) first to the power entry receptacle on the hub rear panel and then to the wall. Install the Hub in a Rack To install the hub in a rack, make sure you have #2 and #3 Phillips screwdrivers. Refer to the illustration and follow the steps. #3 Phillips screwdriver (use large screws with spacers) #2 Phillips screwdriver (use small screws) 1 Power Data Collisi on Link RX 5 13 Link RX 17 Link RX 12 Norma l/Uplin k 24 8145FA 1. 2. Attach the mounting brackets (supplied in the rack mount kit) to the sides of the hub using the screws provided.

Model DS508/DS516/DS524 Dual Speed Stackable Hub Installation Guide 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. The stack of eight hubs can consist of any combination of Model DS508, Model DS516, and Model DS524 hubs daisy-chained together using the supplied cascade cable. The LEDs in the following illustration appear as they would in an operational stack of hubs. Terminator LED On Cascade Up Cascade Down 10/100 Mbps Terminator Bridge 100-240 VAC 50-60 Hz 0.5A Cascade Up Cascade Down 10/100 Mbps Terminator Bridge 100-240 VAC 50-60 Hz 0.5A Cascade Up Cascade Down 10/100 Mbps Terminator Bridge 100-240 VAC 50-60 Hz 0.5A Cascade Up Cascade Down 10/100 Mbps Terminator Bridge 100-240 VAC 50-60 Hz 0.5A Bridge LED On Terminator LED On 8099FA The cascade connectors on the Model DS508, Model DS516, and Model DS524 hubs use a shared circuit. When power is supplied to one of the hubs in a stack, the Terminator LED in the top hub of the stack and the Terminator LED and 10/100 Mbps Bridge LED in the bottom hub of the stack will be on. If power is disconnected from the bottom hub in the stack, the hub above it takes over the bridge function. Furthermore, the remaining hubs continue to operate if power is disconnected from one hub in the stack.
