- D-LINK SWITCH 8 Ports DESKTOP 100MbpsLe DES-1008D possède 8 ports 10/100Mbps, offrant des connexions réseaux Ethernet comme Fast Ethernet à un petit groupe de travail. Ces ports intelligents détectent la vitesse du réseau et négocient automatiquement entre le 100Base-TX et le 10Base-T et également entre les modes full et half duplex. Tous les ports supportent le contrôle de flux 802.3x. Cette fonction minimise les paquets perdus en envoyant des signaux de collision lorsque le buffer du port de réception est plein. Le contrôle de flux est disponible en mode full-duplex. Tous les ports supportent l'auto-négociation MDI/MDI-X. Cette fonction élimine le besoin de câble croisé ou de port uplink. N'importe quel port peut se connecter simplement à un serveur, à un hub ou à un autre switch en utilisant un simple câble droit paires torsadées. Ce switch représente le choix idéal pour les groupes de travail désireux d'augmenter les performances de leur réseau dans un environnement client/serveur. Les ports peuvent être connectés à des serveurs en full-duplex, ou à des hubs en half-duplex. Avec un coût de connexion par port très économique, ce switch peut être installé pour des connexion directes depuis les PCs. Ainsi, les goulots d'étranglements sont soulagés en offrant à chaque station une bande passante dédiée sur le réseau.
- SWITCH 8 1000 MB DESKTOP 1GBSwitch 8 ports Gigabit DGS-1008D Fonction d'économie d'énergie pour une consommation réduite de 40%* 8 ports Gigabit Ethernet Installation plug-and-play *Valeur calculée sur la base d'un jour de semaine classique, où les PC sont utilisés 10 heures, éteints 14 heures et connectés au switch à l'aide de câbles de 20 m. Le switch de bureau DGS-1008D (version Green Ethernet) introduit le concept d'économie d'énergie dans le secteur des réseaux destinés aux télétravailleurs et aux petites et moyennes entreprises (PME). Fonctions d'économie d'énergie Lorsqu'un périphérique relié au switch DGS-1008D (version Green Ethernet) est mis hors tension, ce dernier place le port correspondant en mode veille afin de réduire la consommation d'énergie. Le switch est en outre capable de détecter la longueur du câble Ethernet, en fonction de laquelle il adapte l'alimentation : des économies supplémentaires sont ainsi réalisées (sans cela, la puissance d'alimentation en excès se dissiperait sous forme de chaleur). Grâce à l'association de ces deux fonctions, vous pouvez réaliser jusqu'à 40 % d'économie sur l'énergie consommée par votre switch*. *Valeur calculée sur la base d'un jour de semaine classique, où les PC sont utilisés 10 heures, éteints 14 heures et connectés au switch à l'aide de câbles de 20 m. 8 ports Gigabit en cuivre En utilisant, pour la transmission, vos câbles à paire torsadée en cuivre de Catégorie 5 ou plus, connus pour leur faible coût, ces ports vous permettent de migrer instantanément vos serveurs vers une liaison Gigabit sans avoir à installer des câbles à fibre optique neufs et coûteux. Les ports Gigabit offrent une bande passante dédiée pour vos serveurs fonctionnant à 2000 Mbps en mode bidirectionnel simultané. Cela se traduit concrètement par un désengorgement des voies d'accès aux données du serveur. Contrôle de flux IEEE 802.3x Cette fonction permet d'ajuster le flux de données entre le switch et le serveur et garantit un transfert fiable des données. En mode bidirectionnel simultané à 2000 Mbps, le switch offre à vos serveurs des canaux de données haut débit qui limitent les pertes de données lors du transfert. Auto-négociation de câble croisé MDI/MDIX Tous les ports prennent en charge la détection automatique de câble croisé MDI/MDIX. Les câbles croisés, de même que les ports de liaison montante, sont ainsi inutiles. Vous pouvez connecter n'importe quel port à un serveur, à un concentrateur ou à un switch en utilisant simplement un câble standard droit à paire torsadée. Installation plug-and-play Le switch s'intègre parfaitement à votre matériel réseau existant (Ethernet, Fast Ethernet ou Gigabit Ethernet), ce qui vous permet de conserver l'intégralité de votre parc matériel ou logiciel existant. Il vous suffit de brancher les câbles sur le switch pour que votre réseau soit entièrement opérationnel en quelques minutes seulement.
