Package Contents i Quick Installation The CheetaHub Power-3012A is a Class I Fast Ethernet repeater. It contains 12 100BASE-TX Fast Ethernet ports. This hub also includes two stack ports on the rear panel, allowing you to stack up to 5 hubs, and one slot for optional switch modules which support an additional Fast Ethernet connection (100BASE-TX or 100BASE-FX). The smart design built into the front display panel provides a friendly interface that simplifies installation and network troubleshooting. If you are already familiar with basic network operations, you should be able to install this hub as described below: 1. Unpack the CheetaHub. 2. Find a location close to the network devices you need to connect, and within easy reach of an electrical outlet. 3. Mount the hub on a desktop or any other flat surface. If you are installing multiple hubs, you can stack them on top of each other (after attaching the foot pads), or install them in a standard EIA 19-inch rack. 4. Connect any devices that use a standard network interface to the RJ-45 MDI-X station ports; e.g., a workstation, server or router. Use 100Q Category 5 STP or UTP cable to connect to the hub, and be sure the length of any twisted-pair connection does not exceed 100 meters (328 feet). Refer to Chapter 3 for sample configurations. 5. If you are stacking multiple hubs, connect the FlexBus stack cable between the “Out” and “In” backplane ports on adjacent hubs. Run a simple chain starting at the Out port on the top hub in the stack, and ending at the In port on the bottom hub in the stack. No more than 5 hubs can be connected via the backplane bus. Quick Installation iii CheetaHub Power-3012A User’s Guide 6. To connect a Fast Ethernet switch, run straight-through twisted-pair cable from the MDI daisy-chain port on this hub (Port 12) to any MDI-X station port on the other device (or vice versa). Refer to Figure 3.3. If necessary, you can also cascade between two station ports using crossover cable. 7. To uplink to the network via a Fast Ethernet switch port, you can install one of the optional switch modules. The 100BASE-TX module can be uplinked to Fast Ethernet networks by attaching it to a switch or another repeater hub. It can also be used to provide dedicated access for a heavily used file server or a power user. Or you can use a 100BASE-FX module to connect to a remote site up to 2 kilometers (1.24 miles) away. (Refer to Chapter 2 for a more detailed description of length restrictions for fiber optic cable.) The transmission mode is set by auto-negotiation to full or half duplex for both the 100BASE-TX and 100BASE-FX modules. The speed is set at 10 or 100 Mbps using auto-sensing for the 100BASE-TX module; while the speed of the 100BASE-FX modules is fixed at 100 Mbps. 8. Verify network communications by ensuring that: • you have made all the nece...
