[. . . ] EZ SwitchTM 10/100/1000 Manuale utente Dalla linea SMC EZ di soluzioni LAN dal costo ridotto per gruppi di lavoro Settembre 2003 Numero pubblicazione # 150000005200H R01 INDICE Introduzione . 9 Diagnosi degli indicatori dello switch . 11 Assegnazione dei pin per collegamenti 10BASE-T/100BASE-TX . 11 Assegnazione dei pin per collegamenti 1000BASE-T . [. . . ] Con i connettori RJ-45 utilizzare solo cavi di tipo doppino conformi agli standard FCC. 1 8 8 1 Usare un cavo di tipo doppino non schermato (UTP) o schermato (STP) per le connessioni RJ-45: cavo Categoria 3 o superiore da 100 Ohm per connessioni a 10 Mbps o cavo Categoria 5 o superiore da 100 Ohm per connessioni a 100 Mbps. Controllare inoltre che la lunghezza dei cavi di tipo doppino non superi i 100 metri (328 piedi). 11 CAVI Grazie al supporto automatico dell'operazione MDI/MDI-X per tutte le porte dello switch è possibile usare cavi diretti per tutte le connessioni di rete a PC, server o ad altri switch o hub. Nei cavi diretti i pin 1, 2, 3 e 6, di un'estremità del cavo, sono collegati direttamente ai pin 1, 2, 3 e 6 dell'altra estremità del cavo. La tabella sottostante illustra gli schemi dei contatti per le porte 10BASE-T/100BASE-TX MDI-X e MDI. Pin 1 2 3 6 4, 5, 7, 8 Denominazione segnale MDI-X Ricezione Dati Più (RD+) Ricezione Dati Meno (RD-) Trasmissione Dati Più (TD+) Trasmissione Dati Meno (TD-) Non usato a 10/100 Mbps Denominazione segnale MDI Trasmissione Dati Più (TD+) Trasmissione Dati Meno (TD-) Ricezione Dati Più (RD+) Ricezione Dati Meno (RD-) Non usato a 10/100 Mbps Assegnazione dei pin per collegamenti 1000BASE-T La tabella sottostante illustra gli schemi dei contatti per le porte 1000BASE-T MDI e MDI-X. Queste porte richiedono che siano collegate tutte e quattro le coppie di cavi. Si noti che per il funzionamento a 1000BASE-T tutte e quattro le coppie di cavi sono usate per la trasmissione e la ricezione. Per le connessioni 1000BASE-T usare un cavo di tipo doppino Categoria 5, 5e o 6 da 100 Ohm non schermato (UTP) o schermato (STP). Sostituire tutti i cavi di collegamento Categoria 5 con cavi ad alte prestazioni Categoria 5e o 6. Ridurre il numero di connettori usati nel collegamento. Ricollegare qualcuno dei connettori del collegamento. 14 PRODUCT SPECIFICATIONS EZ Switch 10/100/1000 Standards Conformance IEEE 802. 3 IEEE 802. 3u IEEE 802. 3x IEEE 802. 3ab Communication Rate 10, 100, and 1000 Mbps Communication Mode Full or half duplex at 10/100 Mbps Full duplex at 1000 Mbps Media Supported 10BASE-T: 100-ohm Category 3 or better twisted-pair 100BASE-TX: 100-ohm Category 5 or better twisted pair 1000BASE-T: 100-ohm Category 5, 5e, or 6 twisted-pair Number of Ports SMC8505T: 5 RJ-45 1000BASE-T ports SMC8508T: 8 RJ-45 1000BASE-T ports Indicator Panel Power Ports: Link/Act, 1000M, 10/100M Dimensions 19. 64 x 11. 65 x 3. 66 cm, (7. 76 x 4. 6 x 1. 44 in) 15 PRODUCT SPECIFICATIONS Weight SMC8505T: 0. 59 kg (1. 309 lbs) SMC8508T: 0. 62 kg (1. 378 lbs) MAC Address Table 8 K entries Memory Buffer 768 Kbits per unit Power Consumption SMC8505T: 12 Watts SMC8508T: 15 Watts Power Requirement DC input SMC8505T: 12 V, 1 A SMC8508T: 12 V, 1. 25 A Temperature Operating: 0 ~ 40 ºC / 32 ~ 98 ºF Storage: -40 ~ 70 ºC / -40 ~ 158 ºF Humidity 10% to 90% non-condensing EMC/Safety Compliances CE Mark Immunity EN 61000-4-2/3/4/5/6/8/11 Emissions FCC Class B, CISPR Class B, EN 61000-3-2/3 Safety CSA (UL1950, CSA 22. 2. 950), TUV/GS (EN60950) 16 COMPLIANCES FCC - Class B This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instructions, may cause harmful interference to radio communications. However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient the receiving antenna · Increase the separation between the equipment and receiver · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected · Consult the dealer or an experienced radio/TV technician for help EC Conformance Declaration - Class B SMC contact for these products in Europe is: SMC Networks Europe, Edificio Conata II, Calle Fructuós Gelabert 6-8, 2o, 4a, 08970 - Sant Joan Despí, Barcelona, Spain.
