Quick Installation The CheetaHub Power-3012B contains 12 RJ-45 ports for 10 Mbps or 100 Mbps Ethernet connection (detected by autosensing). This dual-speed hub contains two internal repeater buses – one for 10 Mbps traffic and another for 100 Mbps traffic. Traffic passing between attached devices that operate at the same speed is isolated within the appropriate repeater bus. An internal Ethernet switch, consisting of a 10 Mbps and a 100 Mbps switching port, is used to link the repeater buses.
CheetaHub Power-3012B User’s Guide Attach PCs or daisy-chain to another device via the RJ-45 ports Use the correct twisted-pair cable Cascade limitations Limit total network span 4. Connect PCs or other network devices to the RJ-45 ports. Connect any devices that use standard network interface cards to the RJ-45 (MDI-X) station ports (e.g., a workstation, server, bridge or router). This hub uses auto-sensing to dynamically set the required transmission speed at 10 Mbps or 100 Mbps for the RJ-45 ports.
CheetaHub Power-3012B User’s Guide Attach to alternate media types via the Class I MII port Limits on total network span also apply to MII port 5. Connect other media types using the D-type MII port. You can also connect to other network devices using the media independent interface (MII) on the back panel. You can attach to 100BASE-TX (operating at 100 Mbps only), 100BASE-T4 or 100BASE-FX media types by plugging the appropriate transceiver into the MII connector.
