NETGEAR GSM4328 — M4350-24G4XF 24x1G PoE+ and 4xSFP+ (648W base, up to 720W)

NETGEAR GSM4328 Fully Managed Gigabit PoE+ Switch with 10G Fibre Uplinks

The NETGEAR GSM4328 (M4350‑24G4XF) is a fully managed Layer 3 Gigabit PoE+ switch designed for
SMB and professional AV environments that require reliable powered access, high‑speed fibre uplinks,
and enterprise‑grade scalability. As part of the NETGEAR M4350 platform, the GSM4328 delivers advanced
switching capabilities with simplified deployment for both IT and AV‑over‑IP networks.

High‑Density Gigabit PoE+ Access

The GSM4328 provides 24 × Gigabit Ethernet PoE+ ports, each capable of delivering up to
30W per port. This makes it ideal for powering wireless access points, IP cameras,
VoIP phones, and AV endpoints while maintaining consistent Gigabit performance across the access layer.

Expandable PoE Power for Growing Networks

With a 648W base PoE budget and support for power expansion up to
720W, the GSM4328 accommodates growing numbers of powered devices without
requiring external power injectors. This flexibility makes it well suited for evolving SMB and AV installations.

10G SFP+ Uplinks for Aggregation and Backbone Connectivity

The switch includes 4 × 10G SFP+ fibre uplink ports, providing high‑speed connectivity
to aggregation or core switches. These uplinks ensure sufficient bandwidth for AV‑over‑IP streams,
wireless traffic, and data‑intensive applications without creating network bottlenecks.

Enterprise‑Grade Layer 3 Switching with AV Optimisation

Built on NETGEAR’s M4350 architecture, the GSM4328 supports advanced Layer 2 and Layer 3 features such as
VLAN segmentation, inter‑VLAN routing, traffic prioritisation, and high‑availability switching.
AV‑optimised enhancements simplify multicast handling and reduce deployment time in complex AV networks.

Quiet, Reliable, and Installation‑Friendly Design

Designed for noise‑sensitive environments, the GSM4328 supports quiet operating modes and a compact
1U rack‑mount form factor. This makes it suitable for offices, conference rooms, AV racks,
and wiring closets where both performance and acoustics matter.
