[. . . ] With store-and-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. Rear Panel The AC power receptacle is located on the rear panel of the switch. Features and Benefits Auto-Negotiation of half or full-duplex on all ports ANSI/IEEE 802. 3u compliance ensures compatibility with standards-based hubs, switches and cards from any vendor Store-and-forward switching ensures error-free transmission Half- and full-duplex flow control prevents packets from being dropped under heavy loading Plug and play Built-in wiring crossovers on all ports allow connections to servers and workstations to be made with straight-through cabling "At-a-glance" LEDs for port and system status monitoring Desktop and rack mountable 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. [. . . ] Be sure to use straight-through twisted-pair cable, maximum 100 meters (328 feet). Note: Alternatively, you can cascade from any crossover port on the switch to a daisy-chain port on another device. You may also connect to crossover ports at both ends if you use a crossover cable. See the "Cable Specifications" and "Connectivity Guidelines" sections of this guide for further information. Selecting a Site Be sure to follow the site selection guidelines below when choosing a location: 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. 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. · Grounding: Rack-mounted equipment should be properly grounded. Particular attention should be given to supply connections other than direct connections to the mains. High-Speed Switch Links TROUBLESHOOTING 1. Symptom Power LED does not light after power on. Probable Causes Power outlet or power cord may be defective. Port and Switch Status LEDs Condition Status Switch is receiving power. Possible Solutions · Check for loose connections. · Replace the power cord. Indicates that the connection between port and attached device is valid. Flashing Green Indicates that the switch is transmitting or receiving data. [. . . ] Each wire pair must be attached to the RJ-45 connector in a specific orientation. Be sure to hold the connectors in the same orientation when attaching the wires to the pins. COMPLIANCES FCC Class A This equipment has been tested and found to comply with the limits for a Class A digital device pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. [. . . ]
