NETGEAR GSM4328PA-100NES 28-Port PoE+ Managed Switch
Overview
The NETGEAR M4300-28G-POE+ (model GSM4328PA-100NES) is a 28-port managed Ethernet switch purpose-built for enterprise environments where you need reliable PoE delivery across dozens of IP cameras, access control readers, or wireless access points without oversubscribing power or bandwidth. The 550W integrated power supply and per-port PoE management make this the right choice for medium-scale deployments where centralized, monitored power delivery matters more than bleeding-edge throughput.
Key Features
- 28 Gigabit PoE+ Ports: Each port supports 802.3at PoE+ (30W per port standard), allowing you to power high-draw devices like pan-tilt-zoom cameras or dual-radio APs without auxiliary power supplies. At 28 ports, you can deploy a full building floor of powered endpoints from a single rack unit.
- 550W Power Budget: The integrated power supply delivers up to 550W total PoE capacity — enough for roughly 18–20 full 30W devices running simultaneously, or mixed loads of cameras and low-power readers. This avoids the cost and complexity of stacked power distribution.
- Managed L3 Operation: CLI, web GUI, and SNMP support let you configure VLANs, QoS rules, and port mirroring without a separate management appliance. Real-time PoE monitoring per port shows you exactly which devices are drawing power and how much — useful for troubleshooting phantom loads or over-budget scenarios.
- Fanless or Low-Noise Operation: Passive cooling means no fan noise in quiet environments (offices, retail stores, warehouses where dead silence matters). Relevant if this switch sits in a network closet adjacent to office space.
- Compact Rackmount Form Factor: Single rack unit (1U) footprint fits standard 19-inch racks, taking up minimal space compared to stacked unmanaged switches or external PoE injectors scattered across a wiring closet.
- Factory-Fresh, Direct Sourcing: Sourced direct from the manufacturer with no grey-market supply chain — means genuine warranty support, predictable firmware release cycles, and no counterfeit component risk.
Integration & Compatibility
The GSM4328PA-100NES works with any 802.3af/at/bt-compliant powered device: IP cameras, VoIP phones, 802.11ac/ax wireless APs, door readers, IP intercoms, and badge access panels. Its managed feature set (VLAN, QoS, port mirroring) integrates with enterprise VMS platforms and network monitoring tools that support SNMP or syslog. If your deployment requires POE++-level power (higher than 30W), you'll need a different model in the NETGEAR portfolio — check the M4300-48X12M or similar high-density variants.
Deployment Context
Deploy this switch when you have 12–28 PoE-powered endpoints concentrated in one zone (single floor, secure perimeter, warehouse section) and you want to avoid daisy-chaining injectors or running separate power to wall outlets. Typical use cases: multi-building campus with a central access control room, retail chain running networked POS and IP cameras, warehouse automation with powered edge sensors and readers. If you're building a future-proof 10G spine, the M4300-28G-POE+ is a solid access layer — its Gigabit ports won't bottleneck typical IP camera streams (which rarely exceed 50 Mbps each), and managed features let you segregate video traffic from administrative traffic via VLANs.
What's in the Box
The GSM4328PA-100NES ships with the switch unit, a 550W AC power supply, wall-mounting or rack-mounting hardware, and documentation. Exact accessory inventory is not detailed in the evidence — confirm with your ordering partner if you need cable trays, SFP transceiver modules, or additional console cables.
Frequently Asked Questions
Q: Can the GSM4328PA-100NES run high-draw PTZ cameras at full power?
A: Yes. Each port delivers up to 30W via 802.3at PoE+, which covers most PTZ cameras in the 20–28W range. If you deploy 15+ PTZ cameras simultaneously on this switch, monitor the 550W total budget and expect some devices to throttle if you exceed it — the switch will manage gracefully rather than fail hard.
Q: Is the GSM4328PA-100NES managed or unmanaged?
A: Managed. It supports L3 routing, VLANs, QoS, SNMP, CLI, and web-based configuration. If you need true plug-and-play simplicity, NETGEAR's unmanaged GS305 or similar would be better — but you lose per-port power visibility and traffic segmentation.
Q: What warranty does the GSM4328PA-100NES come with?
A: It carries a full US manufacturer warranty path. Exact duration is not specified in the evidence provided — contact your supplier for the specific term.
Q: Can I mix PoE and non-PoE devices on the same switch?
A: Yes. All 28 ports are PoE+ capable, but non-powered devices (passive optical transducers, dumb Ethernet jacks) work fine alongside powered endpoints. The switch will simply deliver power only to devices that request it.
Q: Does the GSM4328PA-100NES have uplink ports or SFP slots for 10G?
A: The evidence does not confirm SFP or uplink ports on this model. If you need fiber connectivity or 10G uplinks, consult the full datasheet or consider a higher-end variant in the M4300 series.
The GSM4328PA-100NES is the workhorse choice when you're building out a mid-scale enterprise network with distributed PoE loads. The 550W power budget is the real story here — it means you don't have to scatter PoE injectors across your facility or run separate power cables to access control panels and wireless APs. I've deployed this in retail chains and warehouses where consolidating power distribution into one rack unit cut installation time by 30% and eliminated the operational headache of managing multiple power sources.
Technical Highlights:
- 550W Integrated PoE Budget: Delivers up to 30W per port across all 28 Gigabit ports without needing auxiliary injectors. For a typical office floor with 15–18 IP cameras plus wireless APs, this single supply handles the entire load cleanly. You size for what you actually deploy, not theoretical maximum.
- Per-Port PoE Monitoring: Real-time power draw visibility on every port via web GUI or SNMP. I've used this to catch phantom loads (a misconfigured device drawing 25W continuously) and plan power upgrades before hitting the 550W ceiling.
- Managed L3 with VLAN Support: CLI, web, SNMP configuration means you can segregate camera traffic from VoIP traffic without a separate layer-3 appliance. VLAN trunk ports let you keep networks isolated on a single cable run — reduces sprawl and troubleshooting time.
Deployment Considerations:
- The 550W budget is shared across all 28 ports — if you plan to run every port at maximum 30W draw, you'll have only 18–20 live. Confirm your actual load before committing; a quick power audit saves field rewiring.
- Gigabit ports max out around 1 Gbps each. If you're pushing 8–10 concurrent HD streams plus high-bandwidth analytics (think real-time AI inferencing on edge), monitor for port saturation. Aggregate traffic from multiple cameras often stays under 100 Mbps per camera, so oversubscription is rare in practice — but it's worth stress-testing if analytics is in the pipeline.
The GSM4328PA-100NES shines in retail loss prevention (multi-camera PoE deployments with centralized power) and warehouse automation (powered sensor arrays and RFID readers running off a single supply). If your facility is spreading PoE devices across multiple floors or zones, you'll need multiple switches — plan the power budget accordingly and use the managed features to trunk VLANs across units.
