Cisco SG102-24 Quick Start Guide - Page 2

Welcome Thank you for choosing the Cisco SF 100-16, SF 100-24, SF 102-24, SG 100-16, SG 100-24, or SG 102-24 Unmanaged Rackmount Switch, a Cisco Small Business network communications device. This guide will familiarize you with the layout of the unmanaged rackmount switch and describe how to deploy the device in your network. For additional information, see www.cisco.com/smb. Network Speed and Auto MDI/MDI-X Detection All ports support network speed auto-negotiation and auto MDI/MDI-X crossover detection. Network speed auto-negotiation automatically selects the best connection speed and mode (half- or full-duplex) for communicating with attached devices. Auto MDI/MDI-X crossover detection automatically adjusts for the cable type (straight-through or crossover) used to connect the unmanaged rackmount switch to other devices. Green Energy-Efficient Technology SG 100-16, SG 100-24, and SG 102-24 switches support Green Energyefficient Technology that increases energy efficiency and helps businesses to use less energy and save money. Traffic Prioritization The unmanaged rackmount switches deliver Quality of Service (QoS); all received packets are examined for QoS priority encoding. The switch reads the priority level and forwards the packet based on that priority level. For example, during heavy loads voice and video traffic are given priority over data traffic. This ensures that time-sensitive traffic gets the highest level of service. Jumbo Frame Support SG 100-16, SG 100-24, and SG 102-24 switches support frames up to 9,000 bytes called jumbo frames. Jumbo Frame support improves network throughput and reduces CPU utilization during large file transfers, such as multimedia files, by allowing larger payloads in each packet.
