10/100/1000Mbps Gigabit Ethernet Desktop Switch (metal) 8 port The GSD-803 are 8-Port 10 / 100 / 1000Mbps Gigabit Ethernet switches in compact housing for easily desktop deployment. Providing 16Gbps non-blocking switch fabric as well as 8K MAC Address table, the GSD-803 support 802.3x full duplex flow control and also offer wire-speed packet transfer performance without risk of packet loss. The Gigabit ports with jumbo frame feature supported can handle extremely large amounts of data transmission in a secure topology linking to a backbone or high-power servers. All RJ-45 copper interfaces support 10 / 100 / 1000Mbps auto-negotiation for optimal speed detection through RJ-45 Category 3, 4, 5 or above cables. MDI / MDI-X auto detection is provided for direct wire connection to any Ethernet device without requiring crossover cables. •Complies with IEEE802.3, 10Base-T, IEEE802.3u, 100Base-TX and IEEE802.3ab, 1000Base-T •IEEE802.3x, full-duplex flow control compliant; back-pressure, half-duplex flow control •10 / 100 / 1000Mbps 5 / 8-port Gigabit Ethernet Switch (RJ-45) •8K MAC address table auto-ageing, 112K bytes packet buffer •9.6K Jumbo packet size support •Per port Auto-MDI, MDI-X detection •Non-blocking, Store and Forward switching architecture •Automatic source address learning and aging Application Backbone Switch With a non-blocking design and compact size, PLANET's GSD-803 8-Port 10/100/1000Mbps Gigabit Ethernet switch make it easy to install a Fast Ethernet network, and can be used to build a Gigabit high-bandwidth switched network quickly and easily. You can directly connect to department switches and / or backbone servers.
