NETGEAR M4300-28G-PoE+ — 26-портовый управляемый сетевой коммутатор 1G/10G PoE+ с SFP+, комм

M4300 28G PoE+ Managed Switch 480W Expand your small to medium-sized business’s network capacity with the M4300-28G PoE+ 26-Port 1G/10G PoE+ Compliant 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. There are no license requirements to support video broadcast and other high-bandwidth applications. Key Features 24 x Gigabit Ethernet PoE+ Ports 2 x 10G Ethernet Ports 2 x 10G SFP+ Ports 128 Gb/s Switching Capacity 95.2 Mpps Forwarding Rate 800 MHz Processor | 1GB RAM Rackmount Design 480W Power Budget 550W 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. Provides 24 Gigabit PoE+ 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 Hot swap APS550 W power supplies deliver 480 W redundant PoE+ budget across 24 ports or 720 W in share mode With 176 Gbps non-blocking fabric, M4300-52G-PoE+ delivers L2/L3/L4 and IPv4/IPv6 rich services for 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 models such as M4300-52G-PoE+ can stack with 10 Gigabit models enabling line-rate spine and leaf topologies. 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, M4300 10G models can stack with M4300 1G models creating ‘spine and leaf’ topologies, reducing oversubscription, even enabling line-rate aggregation to the spine.
