Quick Installation Guide Introduction The CheetaHub Power-3008P/16P provides 8 (16) RJ-45 ports that automatically adjust to the speed of the attached device (for 10Mbps Ethernet or 100Mbps Fast Ethernet connections). These dual-speed hubs contain two internal repeater buses – one for 10Mbps traffic and another for 100Mbps traffic. Traffic passing between attached devices that operate at the same speed is confined within the appropriate repeater bus. But when traffic must pass between 10 and

CheetaHub Power-3008P/3016P containing the destination node via a 2-port switch that connects the two repeater buses. By confining traffic to its respective collision domain, and only forwarding traffic to the other segment when required, the overall load on the network is significantly reduced. These hubs provide a friendly design that simplifies installation and network troubleshooting. The following figure shows the components of the EH3016P: Mounting the Hub These hubs can be placed direct

Quick Installation Guide 2. Place the first hub on a firm flat surface where you want to install the stack. 3. Repeat step 1 for each hub before stacking them. The rubber foot pads cushion the hub against shock/vibrations and provide space between each hub for ventilation. Mounting Hubs in a Rack Please comply with the following instructions to ensure that your hub is securely mounted in the rack. 1. Use a standard EIA 19-inch rack. 2. Use the brackets and screws supplied in the rack mounting k

The RJ-45 ports support 10Mbps and 100Mbps Ethernet connections. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. Using a hub in a stand-alone configuration, you can network up to 8 (16) end nodes. Do not plug a phone jack connector into any RJ-45 po

Quick Installation Guide cabling will be limited to 5 meters (16 feet). The only way to extend the inter- hub cabling, would therefore be to reduce the length of the cabling used to attach the end nodes to the hubs. Ethernet Switch - There are no formal restrictions on cascade length if a device is connected to a switch, which effectively breaks up the collision domain. When a collision domain is broken up by a device like a switch, cascade length is limited only by the time-out requirement

Quick Installation Guide Connecting to a Network Backbone - You can easily connect to a collapsed backbone switch via the RJ-45 MDI daisy-chain port on the front panel. Because a switch breaks up the collision domain, it can be used to connect multiple CheetaHubs.
