INTORDUCTION Product Introduction EH-2400 is a standard Ethernet concentrator that retimes and re-transmits the signal to each network station on the LAN. It simplifies the implementation of twisted-pair Ethernet compatible networks following the IEEE 802.3 10Base-2/5/T CSMA/CD standard. Each Hub has twenty-four modular RJ-45 STP ports and one BNC port .
GENERAL DESCRIPTION Front Panel of EH-2400 On the front panel of EH-2400, there are Power, Collision, Jabber, utilization LEDs. For each RJ-45 STP port, there are two LED indicators - TX/RX LED and Partition LEDs. These LEDs help in diagnosing line troubles and indicate the status of data transmission.
BNC port and Coaxial Thin Cable EH-2400’s thin coaxial port can be connected to either a computer or another hub. In order to user the thin coaxial port, you will need one thin coaxial cable, two 50-ohm terminators and T-connectors.
EH-2400 Installation Follow the instructions below to set up EH-2400. Step 1. Select a suitable place to put the hub or to install. Make sure there is an AC outlet nearby. Step 2. Power off all of the computers, hubs, or other devices that will be connected to the hub.
CHAPTER 4 TROUBLESHOOTING SYMPTOM: The power LED is not lit. SOLUTION: If the power LED is not lit after the power cord is plugged into the concentrator and the power outlet, there may be a power fault. 1.First verify if there is power at the power outlet by plugging in a device which is known to operate.
