Brand : Planet
Warranty : 2-year Lin Haw warranty

The GSD-503 are 5-Port 10 / 100 / 1000Mbps Gigabit Ethernet switches in compact housing for easily desktop deployment

Providing 10Gbps non-blocking switch fabric as well as 8K MAC Address table, the GSD-503 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. 

Backbone Switch
With a non-blocking design and compact size, PLANET's GSD-503 5-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.
