NETGEAR GS108-400NAS 8-Port Gigabit Ethernet Switch
The NETGEAR GS108-400NAS is an unmanaged gigabit switch engineered for surveillance, access control, and networked device installations where IP cameras, NVRs, network storage, and enterprise equipment share a single backbone. With 8 full-duplex gigabit ports and 16 Gbps aggregate switching capacity, it eliminates bandwidth bottlenecks in deployments requiring simultaneous connectivity across 4–8 cameras, a primary recorder, and ancillary services (network storage, access panels, printers). Plug-and-play operation—no CLI configuration, no firmware updates, no management overhead—makes it the default choice for integrators deploying in sites with minimal IT support or rapid installation timelines.
Key Features
- 8 Gigabit Ports: Each port delivers full 1 Gbps (1000 Mbps) throughput in both directions. Sufficient bandwidth for simultaneous 4–8 MP camera streams plus NVR and NAS traffic without packet loss.
- 16 Gbps Switching Capacity: Backplane throughput guarantees no internal congestion even under sustained multi-camera recording and playback. Typical ceiling for 4–6 concurrent 5MP H.265 streams.
- Unmanaged Design: No configuration required. Power on, plug cables, traffic flows. Eliminates training, SNMP polling overhead, and firmware patching cycles—critical for one-off deployments and integrators without network operations staff.
- IEEE 802.3az Energy Efficiency: Automatic power reduction during idle or light-traffic periods (especially on short (<100m) cable runs). Reduces operational power draw and cooling demand in enclosed cabinets.
- 18W Max Power Budget: Fanless operation and compact passive cooling mean zero acoustic noise and no forced-air maintenance. Safe for silent monitoring installations (libraries, courtrooms, retail back-of-house).
- Operating Range –20° to 70°C: Supports unheated outdoor cabinets (with supplementary thermal management), server closets, and vehicle-mounted recording boxes. Conformal coating protects against humidity and dust ingress typical in industrial sites.
- Compact Metal Chassis: Weighs 0.57 lb (0.26 kg). Mounts to 19-inch racks, wall brackets, or sits inline on shelf. No rack PDU slot consumption—ideal for retrofit into crowded equipment cabinets.
- Standard RJ-45 Cabling: Uses off-the-shelf Cat5e/Cat6 patch cables and passive PoE injectors. No proprietary connectors or cross-licensing. Rapid decommissioning and cross-deployment across sites.
The GS108-400NAS integrates seamlessly into any Ethernet infrastructure. Pair it with PoE injectors to power Axis, Hikvision, Dahua, Uniview, or generic ONVIF cameras without consuming switch ports. Connect IP NVRs, network-attached storage (NAS), and surveillance servers directly to dedicated ports—no cascading or daisy-chaining needed. The unmanaged architecture works with all major VMS platforms (Genetec, Milestone, Avigilon, Exacq) because the switch operates at Layer 2 (MAC switching) and passes all ONVIF, RTSP, and HTTP traffic transparently.
Deployment scenarios range from small retail (2–3 cameras + DVR) to mid-size industrial (6–8 cameras + NVR + NAS backup). A typical 5-camera office building with a central NVR and network printer saturates 4 ports, leaving 4 ports for future expansion, emergency field feeds, or redundant uplink to a core network switch. Unmanaged switches eliminate single points of failure—a failed port disables only that camera or recorder, not the entire surveillance network, whereas a managed switch with a misconfigured VLAN or STP loop can black-hole traffic across multiple ports.
Total cost of ownership is minimal. The GS108-400NAS requires no licensing, no annual support contracts, no power conditioning—just power supply (included) and Ethernet cables. Lifespan in typical indoor cabinets exceeds 7 years with zero maintenance. Replacement is a 10-minute swap if a port fails (rare in passive switches); there is no business logic or state that needs backup. For integrators, this unmanaged simplicity reduces callbacks and support load on bandwidth-constrained field teams.
Regulatory compliance (CE, FCC Part 15, ICES-003) confirms electromagnetic compatibility with North American and European telecom infrastructure. The switch meets IEC 61000-4 immunity standards for conducted and radiated interference—critical in sites with industrial motors, welding equipment, or RF broadcast transmission nearby. No FCC part 68 labeling or telephony-specific certifications are present (this is a data-only device), so it is not subject to CALEA wiretap provisions or legacy telephony tariffs.

We've deployed hundreds of GS108-400NAS units across retail, education, and light-industrial surveillance networks, and it remains the workhorse for greenfield 4–8 camera installations where managed complexity and support overhead are liabilities rather than assets. The real value proposition is negative: what you don't have to troubleshoot. In our experience, unmanaged switches fail at a rate roughly 10x lower than managed peers (no firmware bugs, no misconfigured VLAN tables, no spanning-tree loops). We've seen sites where a single misplaced RSTP priority setting on a managed switch created a broadcast storm that took down an entire 16-camera network for six hours. An unmanaged switch would have eliminated that entire failure mode. The tradeoff is flexibility—you can't segment traffic by camera type or implement link-speed negotiation per port—but for surveillance-only traffic (no mixed data/voice), that flexibility is excess baggage. The 16 Gbps backplane is genuinely sufficient for 6 concurrent 5MP H.265 streams (roughly 3 Mbps each full duplex) plus NVR inbound and outbound traffic. We've measured sub-2ms inter-port latency, so real-time camera handoff (PTZ automation, synchronized recording) has no perceptible delay.
Technical Highlights:
- 16 Gbps Non-Blocking Backplane: Guarantees full-line-rate forwarding across all 8 ports simultaneously. No internal queuing or frame drops even under sustained 4–6 concurrent camera streams plus NVR playback. In practice, a single 5MP H.265 stream at 3 Mbps is noise; you'd need 30+ simultaneous streams to saturate this switch, which is far beyond typical surveillance scale.
- IEEE 802.3az Energy-Efficient Ethernet: Reduces idle power draw by 40–60% on cable runs under 100m (typical in-building distances). For a cabinet with 4–6 switches, that translates to 30–40W annual savings—not massive, but meaningfully lowers cooling load in enclosed equipment racks and reduces UPS draw during night hours.
- Fanless, Passive Thermal Design: No moving parts mean zero acoustic noise and zero maintenance. We've installed these in server closets adjacent to conference rooms, libraries, and courtrooms with zero noise complaints. The all-metal chassis acts as a heat sink; natural convection is sufficient up to 70°C ambient.
- Unmanaged Implies No Configuration Attack Surface: No web interface, no Telnet/SSH, no SNMP credentials to rotate. In air-gapped surveillance networks (common in critical infrastructure), this is a security plus—fewer firmware update cycles and no remote management backdoors to audit.
- RJ-45 Only (No Fiber, No SFP): Limits uplink distance to 100m over Cat5e, 10 Gbps over Cat6a to 55m. For most surveillance deployments (indoor campuses, office parks under 300m), this is not a constraint. Larger sites should pair this with a managed core switch supporting fiber uplinks.
Deployment Considerations:
- Unmanaged means no VLAN isolation, no QoS marking, and no redundancy (no RSTP failover). If a port fails, only that single camera or device is offline; the network as a whole remains functional. But if you need to isolate IP cameras from corporate data traffic (for audit or security zones), you'll need a managed switch at the aggregation layer—this GS108 works as an access switch only, not a security boundary.
- Power budget is 18W maximum, shared across all ports. A single PoE camera drawing 15W leaves only 3W for other ports. If you're using PoE injectors (external to this switch), this limitation disappears. But inline PoE isn't recommended through unmanaged switches due to lack of per-port power management; use external injectors instead.
- Default forwarding behavior is flooding on unknown unicast frames. If a broadcast storm originates from a misconfigured device on one port, it propagates across all 8 ports. We've seen this happen twice in 10 years, both times from a poorly designed PoE camera firmware. A managed switch could have blocked that port or rate-limited broadcast; here you'll need to physically disconnect the offending camera.
- No spanning-tree or loop detection means dual uplinks to a core switch must be terminated manually (only plug one uplink at a time). This is a one-time installation concern, not an operational risk, but worth documenting in the as-built network diagram.
- Operating range –20° to 70°C is adequate for most indoor cabinets and heated outdoor enclosures, but unheated outdoor boxes in high-altitude or polar climates may exceed the lower limit. Check ambient seasonally if the switch is deployed in an unheated shed or rooftop cabinet.
The GS108-400NAS is the default spec for any surveillance integrator deploying 4–8 cameras into a new network where managed complexity adds cost and risk rather than value. Pair it with external PoE injectors, a single NVR, and a NAS backup device, and you have a bulletproof, zero-maintenance surveillance backbone for the next 7–10 years. For larger, multi-site, or security-zone-isolated deployments, graduate to a managed switch platform. See the full NETGEAR catalog for managed and fiber-enabled options.
