Especially designed for SOHO (Small Office/Home Office) users, this cost-effective, space-saving solution is for an environment of less than 5 users. The plug-and-play and auto-negotiation capabilities allow the switch to auto-detect its link partner (such as an ethernet adapter) quickly. Each port provides full bandwidth (maximum with 200 Mbps in full duplex mode) without the traditional hub's collision phenomenon downgrading the performance. An uplink (cascade) port is provided to link to another switch to make it easy to add additional ports. The easy-to-read LED indicators support cable installation and normal operation diagnostics. Automatic source address learning; full and half duplex support. Can be used on desktop or be wallmounted.Input: Five 10/100 Mbps RJ45 portsPlease Note: Once this item is opened, it is non-returnable unless defective.
