NETGEAR M4300-52G — 50-портовый управляемый сетевой коммутатор 1G/10G с SFP+, коммутация 176 Гбит

M4300-52G 50-Port 1G/10G Network Switch with SFP+ Expand your small-to-medium-size business’s network capacity with the M4300-52G 50-Port 1G/10G Managed Network Switch from Netgear . This fully managed rackmount network switch includes Layer 2, 3, and 4 feature sets such as hot-swappable mixed stacking, with up to eight switches in a single logical switch, but no license requirements to support video broadcast and other high-bandwidth applications. Key Features 48 x Gigabit Ethernet Ports 2 x 10G Ethernet Ports 2 x 10G SFP+ Ports 176 Gb/s Switching Capacity 130.9 Mpps Forwarding Rate 800 MHz Processor | 1GB RAM Rackmount Design 150W Power Supply | Redundancy Support The M4300 series scales from 24x1G to 48x10G and up to 384 ports per stack. Nonstop forwarding, spine and leaf, edge-to-core connectivity for unified wired and wireless networks. Unstoppable operation with management unit hitless failover and no service interruption for the clients connected to the other switches in the stack. NETGEAR M4300-52G Stackable Switch for Intelligent Edge Provides 48 Gigabit access ports with 2 10GBASE-T and 2 10GBASE-X SFP+ uplink connectivity All (4) 10G ports are independent and 1G backwards compatible for progressive transition to 10G speeds With 172 Gbps non-blocking fabric, M4300-52G delivers L2/L3/L4 and IPv4/IPv6 rich services for virtualization (Auto-iSCSI prioritization), wireless access layer, IP video and unified communications Virtual Chassis stacking provides non-stop forwarding (NSF) and hitless failover for highest availability (HA) 1 Gigabit model such as M4300-52G seamlessly stacks with 10 Gigabit models enabling line-rate spine and leaf topologies Dual redundant, modular power supplies contribute to business continuity management PoE deployment at the edge Common for intermediate distribution frames (IDF) in K-12, horizontal or vertical ring stacking topologies greatly simplify Power over Ethernet deployments at the edge and bring network resiliency with distributed 10G uplinks in aggregation to the core. Top-of-rack and server installations For midsize server installations, two half-width M4300 10 Gigabit models can be paired in an effective single rack space for redundant top-of-rack. Non-stop switching, non-stop routing stacking technology ensures no single point of failure for servers connecting to the stack. Spine and Leaf topologies For typical collapsed core installations with a variety of 1G and 10G access ports in high-performance local area networks, M43 00 10G models can stack with M4300 1G models creating ‘spine and leaf’ topologies, reducing oversubscription, even enabling line-rate aggregation to the spine.
