Introduction

The "smart" 3Com Baseline Switch 2848-SFP Plus sets new standards among small business Gigabit switches with 48 Gigabit ports and 4 SFP slots. A user-friendly web browser lets even network novices easily set up and maintain a network. Wirespeed, non-blocking Layer 2 throughput and a switching capacity of up to 96 Gbps can handle the most bandwidth-intensive applications. Gigabit ports can be used for connections to high-performance computers, as well as high-demand servers. Class of service (CoS) traffic prioritization makes sure real-time applications run effectively and enables the switch to operate in larger networks. Any of the available ports can be trunked, or aggregated, to create an ultra-high bandwidth pipe to the network core. Copper and SFP-based fiber connections can be mixed together for versatile operation. VLAN support allows administrators to segment their network and divide available bandwidth, while traffic monitoring helps keep the network running at optimum performance even during busy traffic periods. A new Cable Diagnostic Tool is available in this switch allowing users to troubleshoot cabling problems via the Switch web-management interface. Using the straight forward menu based web GUI, the switch performs basic connectivity tests on the cables connected to the switch and helps to identify problems quicker. The switch also promotes "ease of use/plug and play" installation, operating straight out of the box, so it's up and running in minutes. With features like auto MDI/MDIX and autosensing ports, the small business switch eliminates the most common cabling errors and simplifies installation, as well as detecting and adjusting the speed of connected devices to optimize network performance. Small business configurations can vary, so the 3Com Baseline Switch 2848-SFP Plus is designed to operate as a free-standing or rack-mounted unit included mounting kit. The standard one rack-unit-high (1 RU) enclosure optimizes valuable office space. Sturdy design and construction pays off in high reliability and long service life.
