Netgear M4300-28G PoE+ (GSM4328PB)24x1G PoE+ 630W, 2x10G, 2xSFP+ Managed Switch - GSM4328PB-100NES

Product Overview

The NETGEAR M4300-28G PoE+ (GSM4328PB-100NES) is a full-width stackable Layer 3 PoE+ managed switch with 24 Gigabit PoE+ ports, two 10GBASE-T ports, and two 10G SFP+ ports. Built for resilient campus and commercial access layers, this M4300 stackable managed switch pairs license-free Layer 2/3 routing with mixed 10G/1G stacking. It delivers a high PoE budget for access points, IP phones, and IP cameras, making it a practical core or aggregation tier for unified communications and AV-over-IP distribution.

Product Description

The M4300-28G PoE+ provides 24 Gigabit PoE+ access ports plus four 10G uplink/stacking ports (two 10GBASE-T copper and two 10G SFP+), for 28 ports total and 128 Gbps switching capacity. Power comes from an APS1000W supply delivering a 630W PoE budget at 110V (720W at 220V), and a second PSU slot enables 1+1 redundancy or external power supply (EPS) operation. Up to eight units stack together with mixed 10G/1G connections, providing non-stop forwarding (NSF) and hitless failover for business continuity. The complete Layer 2/3/4 feature set is included with no license, covering static, policy-based, RIP, OSPF, VRRP, and PIM routing. The switch is OpenFlow 1.3 / SDN-ready and managed through a single pane with NETGEAR NMS300, alongside CLI, GUI, SNMP, sFlow, and RSPAN for visibility and troubleshooting.

Frequently Asked Questions

How much PoE power does this switch provide?
The APS1000W supply delivers a 630W PoE+ budget at 110V (720W at 220V) across the 24 PoE+ ports, with a second PSU slot available for 1+1 redundancy or EPS.

Can I stack it with other M4300 switches?
Yes. It supports mixed 10G/1G stacking of up to 8 units using the four 10G ports, with non-stop forwarding and hitless failover for resilient operation.

Do I need a license for routing features?
No. The full Layer 2/3/4 feature set, including OSPF, VRRP, and PIM, is included with no separate license.

Is it suitable for AV-over-IP and unified communications?
Yes. The high PoE budget powers APs, IP phones, and cameras, while multicast handling and 10G uplinks support IP video and AV distribution in commercial spaces.

What warranty applies?
The M4300 series is backed by the NETGEAR ProSAFE limited lifetime hardware warranty. Contact our team for current support terms.
