NETGEAR M4300-52G-PoE+ 550W PSU Managed L2/L3/L4 Gigabit Ethernet (10/100/1000) Power over Ethernet (PoE) 1U Black

The NETGEAR M4300-52G-PoE+ (GSM4352PA-100NES) is a managed L2/L3/L4 switch designed for mid-enterprise edge and SMB core deployments. This 1U rack-mountable unit provides 48 Gigabit Ethernet RJ-45 ports, a USB 2.0 port and a console port, a 128 Gbit/s switching capacity and full Power over Ethernet (PoE+) support with a 550W PSU option. The switch supports both IPv4 and IPv6 routing, mixed 1G and 10G stacking, and offers high availability features for continuous network operation.

Advantages

The M4300-52G-PoE+ delivers flexible stacking that allows 10 Gigabit and 1 Gigabit models to interoperate, enabling spine-and-leaf topologies and simplified upgrades. High-availability features such as NSF and hitless failover provide non-stop forwarding across the stack. The device includes a comprehensive L2/L3/L4 feature set (static and dynamic routing, policy-based routing, multicast) without requiring additional licenses and supports industry-standard management interfaces (CLI, GUI, SNMP, sFlow). Redundant power and compact 1U half/full-width options improve deployment flexibility and business continuity.

Suitable for

• Enterprise edge switches for wired access and PoE-powered devices (IP phones, access points, cameras)
• SMB core or collapsed-core deployments requiring L3 routing and high availability
• Wireless access and unified communications environments
• Server room spine-and-leaf stacking topologies with mixed 1G/10G connectivity

How to use

Install the M4300-52G-PoE+ in a standard 19-inch rack using the provided mounting brackets. Connect uplink and access devices to the RJ-45 ports; use SFP+/10G ports on compatible models for 10 Gigabit uplinks or stack links. Configure basic settings through the web GUI or CLI, including VLANs, QoS, PoE prioritization and routing protocols (static, OSPF, RIP). For stacking, connect appropriate 10G ports between units and enable stack mode; the master election and NSF behavior are handled automatically by the system when configured.

Recommendations

For reliable PoE deployments, plan the power budget according to the connected devices and enable Auto-iSCSI prioritization for top-of-rack installations. Use redundant power supplies in critical installations and enable NSF/ hitless failover to maintain service continuity during control-plane events.
