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.
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.
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 kit. 3.
CheetaHub Power-3008P/3016P 3. Connect one end of the cable to the RJ-45 port of the network interface card, and the other end to any available (MDI-X) station port on the hub. 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 port.
Quick Installation Guide cabling will be limited to 5 meters (16 feet). The only way to extend the interhub 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.
CheetaHub Power-3008P/3016P Port and Hub Status LEDs LEDs Condition Status Power Green Hub is receiving power. Link Yellow Indicates a valid 10BASE-T connection between port and attached device. Green Indicates a valid 100BASE-TX connection between port and attached device. Partition Yellow Port has been partitioned due to an abnormal condition. Col Flashing Yellow Indicates that a packet collision has been detected on the indicated segment.
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.

Quick Installation Guide Power and Cooling Problems If the Power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fan on back of the unit is unobstructed and running prior to shutdown.
