Управляемый коммутатор 2 уровня GSM 7224

GSM 7224
24-port Layer 2 Managed Gigabit 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 10/100 switches and Gigabit servers in demanding small networks. The non-blocking design offers full Gigabit throughput simultaneously to all 24 10/100/1000 ports. Layer 2 management functionality delivers reliability, control, and availability. It’s an easy to use solution that delivers maximum performance right out of the box. The very affordable NETGEAR GSM7224 Layer 2 Managed Gigabit Switch creates a more productive — and future-proof — network. With increasing bandwidth requirements from applications
such as video, voice, 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 — extensive VLAN support, resiliency, traffic prioritization, port trunking, port mirroring, RADIUS, SNMP, and DHCP features, as well as broadcast storm protection. Fiber connectivity is enabled through four combination Small Form-factor Pluggable (SFP**) gigabit ports. Network administrators can use any combination of these features to ensure uptime, availability, bandwidth, and throughput.
