48 10/100/1000 Mbps gigabit ports

Non-blocking Bandwidth

Easy, browser-based switch management

High Port Density Gigabit with Browser-based Management Included

Joining NETGEAR’s family of Smart Switches with simple switch management at no extra cost, this 1U high, 48-port Gigabit switch maximizes bandwidth and density for great value and capability. With 48 10/100/1000 Mbps ports, each capable of powering 2000 Mbps of data throughput in full-duplex mode, plus four optional fiber ports, it provides a 96 Gbps backbone and connects servers or power users, delivering large amounts of multimedia, image, and video information in no time at all. Standards-based, it is ideal for combining 10, 100, and 1000 Mbps devices, as it delivers automatic speed and full/half-duplex sensing plus Auto Uplink™ on every port. Four hot-swappable small form-factor pluggable (SFP)** GBIC slots provide optional fiber connectivity for greater distance. An intuitive, Web-browser interface offers simple switch management, making it a snap to monitor switch performance, configure ports, even setup trunks, VLANs, and prioritization.

High Density

48 10/100/1000 Mbps ports deliver full-speed packet forwarding in a 1U size to migrate your network to future-proof functionality. Four SFP GBIC fiber slots provide optional fiber connectivity for greater distance.

Intelligent

Smart Switch capability enables key management features for the value price of an unmanaged switch. Included are performance monitoring, port configuration, VLAN for traffic control, port trunking for increased bandwidth, and Class of Service (CoS) for traffic prioritization.

Right Sized

Ideal for growing businesses who want the benefits of management without the cost. Compatible with Windows, MAC and Linux operating systems.***

Easygoing and Durable

Simple to set up and simple to use for effortless network monitoring and troubleshooting. Made to last, this sturdy switch is housed in a 17-inch metal box and comes with a rack-mounting kit.

** Use with NETGEAR AGM731F 1000BASE-SX SFP GBIC module, NETGEAR AGM732F 1000BASE-LX SFP GBIC module or NETGEAR AGM733 1000BASE-ZX SFP GBIC Module

*** Requires PC for initial discovery of Smart Switch features.
