Product Description

GSM7248 - ProSafe™ 48 Port Gigabit L2 Managed Switch

NETGEAR delivers wirespeed Gigabit performance and a full set of Layer 2 management features with unsurpassed affordability. This next-generation, high-speed switch delivers maximum throughput where you need it — to high-performance workgroups at the edge of the network, or as a backbone for Fast Ethernet switches and high-speed servers in demanding small networks. The non-blocking design offers full Gigabit throughput simultaneously to all 48 10/100/1000 ports to ensure reliable performance. Flexible fiber connectivity is enabled through four combination Small Form-factor Pluggable (SFP**) gigabit interfaces. Layer 2 management functionality delivers reliability, control, and availability. The very affordable NETGEAR ProSafe 48 Port Gigabit L2 Managed Switch GSM7248 creates a more productive — and future-proof — network. With increasing bandwidth requirements from applications such as voice, video, database management, and other services that slow throughput and response time, you can unleash your network and enable maximum productivity with Gigabit Ethernet for today’s high-performance environments. Optimize bandwidth, security, and control with full Layer 2 management capabilities. Network administrators can use any combination of these features to ensure uptime, availability, bandwidth and throughput.
