This dual-speed hub contains 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. The components of the Zilla Hub are shown in the figure below: Zilla Hub Check the Package The Zilla Hub includes: • 1 Zilla Hub • 1 DC Power Adapter • This user guide • 1 registration card (please return) RJ-45 Connectors Accton’s Zilla Hub features 8 10BASE-T/100BASE-TX ports with RJ-45 connectors located on the side panel of the hub. Ports 1-8 are (computer) station ports. To connect to a workstation or server, attach straight-through unshielded or shielded twisted-pair cabling to any station port on this hub. Port 8 doubles as a station (computer) port and a cascade (uplink) port. The cascade port makes it convenient to connect cable from the hub to a station port on another hub or a switch. Mount the Hub The Zilla Hub can be placed directly on your desktop or stuck to a metallic vertical surface (using the magnetic foot pads on the bottom of the hub). Before you start installing the hub, be sure you find a suitable location at the center of the devices you want to link and near a power outlet. Connect PCs to the Hub 1. Remove the rubber cover from an RJ-45 port. Quick Installation Guide 2. Install a 10 or 100 Mbps (10BASE-T or 100BASE-TX) network adapter card and driver in each computer you want to network. 3. Prepare straight-through twisted-pair cables with RJ-45 plugs. Attach one end of the cable to the RJ-45 port of the computer’s network adapter card and the other end to any available port on the hub. Notes: If you are using port 8, be sure the Daisy-Chain switch is set to "COMPUTER." Cascade Devices to the Hub If you need more ports, connect a station port on another device to the cascade port on the Zilla hub with straight- through twisted-pair cable, maximum 5 meters (19.68 feet). 1. To make a direct connection to another compatible hub or switch, use the RJ-45 cascade port 8. Set the port selection switch to HUB and then connect to any station port on the other device. Alternatively, you can connect from any RJ-45 station port on the hub to an uplink port on the other device. 2. Prepare straight-through shielded or unshielded twisted-pair cables with RJ-45 plugs at both ends. Use 100. Category 3, 4 or 5 cable for standard 10Mbps Ethernet connections, or 100. Category 5 cable for 100Mbps Fast 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. Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters (328 feet). 2. To connect to another hub or switch, you may also attach to station ports at both ends if you use crossover cabling. Zilla Hub Verify System Operation Check each connection by viewing the port status indicators shown in the following table. The hub monitors the link status for each port. If the Port indicator fails to light when you connect a device to the hub, follow the troubleshooting advice detailed in the next section. Port and Hub Status LEDs LEDs Condition Status Power On Hub is receiving power. Link On Port has established a valid 10/100 Mbps network connection. Activity Flashing Traffic is traversing the port. Troubleshooting Symptom: Power LED does not light after power on. Cause: Power outlet or power cord may be defective. Solution: 1. Check for loose connections. 2. Check the power outlet by using it for another device. 3. Replace the power cord. Symptom: Port LED does not light after connection is made. Cause: Hub port, network card or cable may be defective. Solution: 1. Check that the hub and attached device are both powered on. 2. Be sure the network cable is connected to both devices. 3. Verify that Category 5 cable is used for 100Mbps connections and that the length of any cable does not exceed 100 meters (328 feet). 4. Check the network card and cable connections for defects. 5. Replace the defective card or cable if necessary.
