The 5 Port Gigabit 10/100/1000Mbps Ethernet Switch, from Cables To Go, is designed for SOHO (Small Office/Home Office) or workgroup users that need to reliably exchange large files. The desktop size metal case provides 5 Gigabit ports. A safety certified internal power supply makes this switch the most robust and cost-effective device for the small networking environment. The plug-and-play and auto-negotiation capabilities allow the Switch to auto-detect its link partner, such as an Ethernet adapter, at top speeds. Each port provides full bandwidth (Maximum with 2000Mbps in full duplex mode) without the traditional collision problems of hubs. Easy-to-read LED indicators make cable installation and normal operation diagnostics a breeze. The 5 Port 10/100/1000 Gigabit Ethernet Switch complies with the IEEE802.3 10BaseT Ethernet, IEEE802.3u 100BaseTX Fast Ethernet Standards and IEEE802.3ab Gigabit Ethernet Standards. It provides Store-and-Forward architecture and full wire speed forwarding and filtering rates. All utp Ports support full/half duplex modes and auto-negotiation as well as Auto-MDI/MDI-X function. Features: Complies with the IEEE802.3 10BaseT Ethernet, IEEE802.3u 100BaseTX Fast Ethernet Standards and IEEE802.3ab Gigabit Ethernet Standards. Provides Store-and-Forward architecture and full wire speed forwarding and filtering rates. All utp Ports support full/half duplex modes and auto-negotiation. All utp Ports support Auto-MDI/MDI-X function. Supports flow control: back pressure for half-duplex mode, IEEE 802.3x for full-duplex mode. Extensive front-panel diagnostic LEDs. External power supply. Compact size is perfect for maximizing space. Please note - once this item is opened it is non-returnable unless defective.
