Stackable Fast Ethernet Hub with 8/12 10BASE-T/100BASE-TX Ports Fast EtherHub Installation Manual INTRODUCTION General Description The EH3008C and EH3012C 100BASE-TX 8/12 port stackable hubs are entry level 100Mbps Fast Ethernet hubs. They are built around a standard 19-inch chassis which allows stand-alone or rack-mounted operation. These 100BASE-TX 8/12 port stackable hubs are economical Fast Ethernet hubs with 8/12 100BASE-TX (RJ-45) ports for workstation connection. An uplink port in the front panel permits cascading to another 100BASE-TX Fast Ethernet hub (when the hubs are not stacked), or to a Fast Ethernet switch. The EH3008C and EH3012C are compatible with the IEEE 802.3u standard. They are easy to install, no DIP switch to set and no software to load. Just plug in the power cord and connect up to 8/12 100BASE-TX station ports. The LINK/ACTIVITY and ERROR indicate status for each port. The Collision and Power LEDs indicate status for overall system. 1 Fast EtherHub Installation Manual Key Features . Compliant with the IEEE802.3u 100Mbps repeater specification . 8/12 100BASE-TX ports for Fast Ethernet connectivity . 19-inch rack mountable . Supports Category 5 unshielded twisted-pair cabling (UTP) . Stackable architecture supports up to 4 hubs with 100BASE-TX . An uplink port on the front panel for cascading to another 100BASE-TX hub (when the hub is not stacked) . Individual port status LEDs for LINK/ACTIVITY and ERROR indication . Global Collision status LED . Compliance with 100BASE-TX Class I (when stacked) and Class II (when stand-alone) . Auto-partitioning of ports receiving excessive collisions 2 Fast EtherHub Installation Manual Package Contents Check your package contents for the following parts: • 8/12 port 100BASE-TX Fast Ethernet Stackable Hub (Fast EtherHub-8se or Fast EtherHub-12se) • Power Cord • Stackable Cable (D-Sub 25 pins) • Rack-mount Kit • User’s Manual If any of these pieces are missing or are damaged, please contact your dealer immediately. 3 Fast EtherHub Installation Manual Hardware Description The Front Panel The front panel contains the 8/12 Shielded Twisted-Pair (STP) ports, one uplink port, and LED indicators. Shielded Twisted- Pair (STP) ports Use any one of the STP ports for connection to a 100BASE-TX node using Category 5 UTP cabling. Each of these ports provides 100Mbps bandwidth for connection to a workstation or server. UPLINK port The uplink port provides cascading capabilities to a second 100BASE-TX Fast Ethernet hub (if the hub is not stacked). 4 Fast EtherHub Installation Manual LED indicators The front panel LED indicators help you monitor the status of each port and connected segments. There are 4 different LEDs on the front panel; including power (PWR), collision (COL), LINK/ACTIVITY and ERROR. This table lists the LEDs and their respective functions. LED Function Color Description Power (PWR) Green Lit: Power On Unlit: Power Off Collision (COL) Amber Lit: Data collision occurred LINK/ACTIVITY Green Lit: Indicates the adapter is connected to the hub Blinking: Receiving data ERROR Yellow Flashing: Data jabber or error Lit: Indicates partition and isolation of port 5 Fast EtherHub Installation Manual The Rear Panel The rear panel of the hub contains the power socket , 2 D-Sub connectors (25 pins) and air fans. Power Socket The power socket accepts AC power of 100 - 240V at 50 - 60 Hz. 6 Fast EtherHub Installation Manual HARDWARE INSTALLA...
