[. . . ] With storeand-forward switching and flow control, maximum data integrity is always maintained, even under heavy loading. Easy installation and reliability make this plug-and-play switch an ideal choice for smooth Fast Ethernet integration. SAMPLE APPLICATIONS Some typical applications for the EZ Switch 10/100 are illustrated below: Features and Benefits N Auto-Negotiation of half or full-duplex on all ports N ANSI/IEEE 802. 3u compliance ensures compatibility with standards-based hubs, switches and cards from any vendor N Store-and-forward switching ensures error-free transmission N Half- and full-duplex flow control prevents packets from being dropped under heavy loading N Plug and play N Built-in wiring crossovers on all ports allow connections to servers and workstations to be made with straight-through cabling N At-a-glance LEDs for port and system status monitoring N Desktop and rack mountable Rear Panel The AC power receptacle is located on the rear panel of the switch. u Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting fixtures and other sources of electrical interference such as radios, transmitters, etc. Make sure that a properly grounded power outlet is within 8 feet (2. 44 meters) of the switch and is powered from an independent circuit breaker. As with any equipment, using a filter or surge suppressor is recommended. INSTALLING THE SWITCH u The EZ Switch 10/100 can be placed on a desktop or shelf, or installed in a standard 19-inch equipment rack. Standalone LAN Equipment Checklist After unpacking the EZ Switch 10/100, check the contents of the box to be sure youve received the following components: EZ Switch 10/100 SMC-EZ108DT Appropriate AC power cable Four adhesive foot pads SMC Warranty Registration Card This User Guide Instructions 1. [. . . ] See the Cable Specifications and Connectivity Guidelines sections of this guide for further information. Front-Panel LEDs The front panel of the switch provides a link status LED for each RJ-45 port. In addition, the front panel also contains status LEDs for at-a-glance system monitoring. The following table details the functions of the various indicators: Selecting a Site Be sure to follow the site selection guidelines below when choosing a location: u High-Speed Switch Links Select a suitable location for the switch: It should be accessible for installing, cabling and maintaining the switch. The temperature and humidity should be within the ranges listed in the specifications. There should be adequate space (approximately two inches) on all sides for proper air flow. TROUBLESHOOTING 1.

Solutions 100M FDX u Before rack mounting the switch, pay particular attention to the following factors: Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rackenvironment temperature is within the specified operating temperature range. Mechanical Loading: Do not place any equipment on top of a rack-mounted switch. Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded. Particular attention should be given to supply connections other than direct connections to the mains. 2 . Symptom Link LED does not light after connection is made. Front-Panel Ports The front-panel ports are dual-speed RJ-45 ports with built-in wiring crossovers. Each port supports Auto-Negotiation, so the optimum communication mode (half or full duplex) and data rate (10 Mbps or 100 Mbps) are selected automatically. Port 8 on the switch doubles as a crossover port and a straight-through daisy-chain port. The daisy-chain port makes it convenient to connect straight-through cable from the EZ Switch 10/100 to a crossover port on another device. Probable Causes Switch port, network card or cable may be defective. Possible Check that the switch and attached device are both powered on. Verify that Category 5 cable is used for 100 Mps connections and that the length of any cable does not exceed 100 meters (328 feet).
