Flexible, Stackable, Enterprise-class High-speed Switching! NETGEAR's low-cost, stackable, Gigabit Ethernet switches deliver maximum throughput & flexibility where you need it ? to high-speed, high-density workgroups at the edge of the network, in the backbone of growing networks or for bandwidth-thirsty file & application servers. The Pro Safe GSM7328S & GSM7352S fully-managed switches deliver 24 & 48 ports of auto-sensing 10/100/1000 Mbps interfaces for high-density copper connectivity. Four hot-swappable small form-factor pluggable (SFP) Gigabit interfaces provide optional fiber connectivity for longer reach Gigabit Ethernet requirements. All switches have two 10 Gigabit Ethernet small form-factor pluggable (SFP+) interfaces & two high-speed, module bays offering modular expansion for 10 Gigabit Ethernet or 48 Gigabit Stacking connectivity. The non-blocking design of the switches delivers simultaneous, full wire-speed, low-latency throughput to all ports. A full suite of Layer 3 switching functionality ensures reliable routing between VLANs & network segmentation where & when you need it, at no additional cost. By configuring the switches into a stack of up to 8 units across a 48 Gbps bi-directional ring, a high-density, single IP-addressable switch can be built. Robust security features include IEEE 802.1x port-based authentication & access control lists, ensuring that only authorized users can access your network. Secure management of the switches is available through Secure Sockets Layer (SSLv 3) for the Web GUI & Secured Shell (SSH) for comm&-line sessions or with SNMP v 3 for network management software. For workgroup deployments in cost-sensitive organizations that require Layer 3 switching, additional Gigabit capacity, high-value price point, flexibility of stacking, & reduced maintenance requirements, NETGEAR's Pro Safe Gigabit Layer 3 Stackable switches deliver the ideal access-edge solution. With their high-value price point, flexible design, & reduced maintenance requirements, NETGEAR's Pro Safe Gigabit Layer 3 Stackable switch solutions yield a high return on investment, & are ideal for delivering highly reliable, converged voice, video, & data services over a single network infrastructure. Powerful In desktop switching environments, wire-speed performance with full Qo S control for all 10/100/1000 interfaces is critical. The 2 built-in 10 GE SFP+ slots & the 2 module bays for 10 GE or 48 Gigabit stacking connectivity provide unprecedented performance, whether you are stacking between switches, attaching servers or aggregating data to the core. Easy to Use Simplify & reduce IT staff workload & mean time-to-repair with intuitive, GUI-based device configuration, & an industry-standard comm&-line interface (CLI). The EZ-Config tool simplifies initial configuration steps to streamline the out-of-box set-up. For easy tracking of port usage, use the text-based port description to label how ports are used. Flexible Stacking Stacking capabilities allow you to build a single-IP unique logical device with up to eight switches utilizing intelligent bi-directional redundant stacking links. Stacking is flexible, it can either be via AX742 kit (48 Gigabit stacking short connectivity) or longer reach 10 GE fiber uplinks. Non-stop Service The new rev 2 hardware now comes with a removable power module as the switch's main power supply. In the event of a power supply failure, the switch will change to use the external RPS device for power, & the internal power module can be replaced without an RMA of the entire switch. This will avoid the problem of service disruption or down time due to power supply failure.
