Product Overview

High-speed, Layer 2 Managed Gigabit Switching
NETGEAR delivers wirespeed Gigabit performance and a full set of Layer 2 management features with unsurpassed affordability. These next-generation, high-speed switches deliver 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 12, 24 or 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 12-, 24- and 48-Port Gigabit L2 Managed Switches, GSM7212, GSM7224 and GSM7248, create 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.

Powerful
Full 12, 24 or 48 10/100/1000 ports and a non-blocking design provide wire speed throughput and maximum bandwidth for the most demanding network environments. Small Form-factor Pluggable (SFP) modules deliver choice in 1000Base-SX, 1000Base-LX or 1000Base-ZX (70Km) optics. The Layer 2 management features optimize bandwidth throughout the network – delivering Gigabit performance to systems, applications, and services. Take advantage of forwarding rates up to 71.4 million pps, and a switching capacity of 96 Gbps.

Easy to Use
Move up to Gigabit power in minutes. Use any of these solutions as a managed switch out of the box – just plug and play! All ports are auto-negotiating and support Auto Uplink™ technology. Choose from two easy-to-use management interface options –Web interface or a command line interface available through console or Telnet. Comprehensive remote administration capabilities reduce the need for on-site administration. Easy to troubleshoot – built-in testing capability locates cable related network problems.

Manageable
Meet your management needs with SNMP (v1, v2c and v3), RMON, Command-Line Interface (CLI) and complete Web-based GUI. Advanced features include up to 512 VLANs, DiffServ traffic prioritization and 802.1p (QoS) for Voice over IP services (VoIP), broadcast storm protection, RADIUS, 802.1x, port trunking, rapid spanning tree, and link aggregation. Full Layer 2 implementation allows you to configure your network for maximum performance, reliability, and availability. Manageable with any popular SNMP-based management software, but optimized for NETGEAR ProSafe Network Management Software NMS100.

Outstanding
Layer 2 management and full Gigabit power at a compelling price. Use at the edge to improve workgroup connections, or at the core to upgrade a Gigabit Ethernet backbone — now you can afford the power your network deserves. Like all NETGEAR products, everything you need is in the box – including rack mount kit, power and serial cables, and more.
