User manual NETGEAR DS516 INSTALL GUIDE

[. . . ] 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.

Wiring hardware, such as punchdown blocks or patch panels, should be complete before installing the hub. 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. 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. Attach the hub (with the mounting brackets) to the rack using two panhead screws with nylon washers. 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. Computers and workstation adapter cards are usually media-dependent interface ports, referred to as MDI or Uplink ports. The figures illustrate the use of straight-through and crossover twisted pair cables.

The RJ-45 connector accepts four-pair Category 3 or Category 5 UTP cable. 12345678 8 1 711EA Model DS508/DS516/DS524 Dual Speed Stackable Hub Installation Guide RJ-45 Connector Pin Assignment 1 2 3 6 4, 5, 7, 8 Normal Assignment on Ports 1­8, 1­16, or 1­24 Input Receive Data + Input Receive Data Output Transmit Data + Output Transmit Data Not used Uplink Assignment on Port 8, 16, or 24 Output Transmit Data + Output Transmit Data Input Receive Data + Input Receive Data Not used Troubleshooting Information Symptom Power LED off Cause No power at hub In a stack, no power at hub but Terminator LED is on Solution Check the power cord connections. In a stack, the termination circuitry gets power from the cascade cable. If one hub in the stack has a faulty power cord or the cord is unplugged, the Terminator LED remains on and the remaining hubs in the stack operate normally. Terminator LED of a Cascade cable not Check for proper connection. middle hub in a stack is on connected properly Link LED off or intermittent Port connection not functioning Check the crimp on the RJ-45 connectors and make sure that the plug is properly inserted and locked into the port at both the hub and device. Make sure cabling is Category 5 and meets the requirements for 100 Mbps operation.
