QNAP Qgd-1602P-C3558: 8 25GBE Poe Ports. - QGD-1602P-C3558-8G-US

QNAP QGD-1602P-C3558-8G-US Smart Edge PoE Switch with VM Support

The QNAP QGD-1602P-C3558-8G-US is an 18-port web-managed switch that does something no commodity PoE switch can: run virtual machines at the edge. Built around an 8-core Intel Atom C3558 processor with up to 64 GB of RAM, this unit ships with 8 GB installed and delivers 20 Gbps of internal switching bandwidth — enough headroom to push camera traffic and local VM workloads simultaneously without forcing you to rack a separate compute appliance. If your project involves a mix of IP cameras, access control readers, and a VMS or analytics server that you'd rather not locate in a distant server room, this is the architecture to evaluate.

Port Configuration and Throughput

The QGD-1602P-C3558-8G-US provides 18 ports in total: 8 x 2.5GbE RJ45 PoE, 8 x 1GbE RJ45 PoE, and 2 x 10GbE SFP+ uplinks. That's 16 PoE-capable ports covering every edge device, with the pair of 10GbE SFP+ ports handling uplink to your core switch or NAS — 10G uplinks mean you're not bottlenecked on the uplink even when multiple cameras are streaming simultaneously. The 20 Gbps internal bandwidth capacity keeps per-port throughput clean under full load rather than collapsing when all 16 PoE ports are active. For a network switch carrying 16 cameras or access points, that non-blocking headroom matters at shift-change or alarm-triggered recording bursts.

PoE Delivery and Power Architecture

PoE support spans IEEE 802.3bt PoE++ (up to 90W on 4 ports) and IEEE 802.3at PoE+ (30W on 12 ports). In practice: the four 90W ports handle PTZ cameras, multi-sensor panoramics, or 802.3bt-class wireless APs that would brown out a standard PoE+ switch. The remaining 12 ports at 30W each cover fixed cameras, readers, intercoms, and IP phones without requiring injectors. Total PoE budget sits at 90W aggregate — size your camera count accordingly and leave headroom for cold-start inrush on PTZ units. Pair this switch with a compatible PoE switch in larger deployments where total wattage demands exceed a single unit.

Edge Compute and VM Architecture

The 8-core Atom C3558 CPU and expandable RAM (up to 64 GB) let you run VMs directly on the switch — a meaningful topology shift for surveillance deployments. Instead of a camera→switch→server→NAS chain across three racks, you consolidate the VMS, edge analytics, or network services onto the switch itself. This cuts both latency and hardware footprint in branch locations, retail sites, or warehouses where a dedicated server is hard to justify. The maximum 64 GB RAM ceiling means you can scale VM density as your workload grows; the 8 GB shipped with the -8G SKU is the starting point, not the ceiling. Browse the full QNAP surveillance line for compatible NAS appliances that pair naturally with this switch's VM-generated storage traffic.

Management

Web-managed configuration means you get VLAN segmentation, PoE scheduling, port mirroring, and QoS without needing CLI expertise, but you retain granular control over traffic policies — important when camera VLANs must be isolated from corporate LAN traffic. For integrators deploying IP cameras across multiple VLANs, web-managed layer-2/3 features handle the segmentation without requiring a full enterprise switch stack. Review the network switch selection guide if you're deciding between unmanaged, web-managed, and full L3 managed options for your project.

Key Features

• 16 PoE Ports (802.3bt/802.3at): 4 ports at 90W PoE++ and 12 ports at 30W PoE+ means you can mix PTZ cameras and multi-sensor units on the same switch without adding injectors — the 90W ports handle even the hungriest 802.3bt devices.
• 2.5GbE Access + 10GbE SFP+ Uplinks: 2.5GbE on the access tier gives camera streams 2.5x the headroom of standard GbE — useful when 4K cameras with high bitrate profiles are in play. The dual 10GbE SFP+ uplinks prevent the uplink from becoming a choke point.
• 20 Gbps Internal Bandwidth: Non-blocking switching capacity means burst traffic from simultaneous recording events doesn't degrade throughput across all ports — a real issue on budget switches running near capacity.
• 8-Core Intel Atom C3558 CPU: Dedicated switching silicon paired with a general-purpose 8-core processor means VM workloads and switching functions don't compete on the same compute resources — the switch fabric runs independently.
• Up to 64 GB RAM: Ships with 8 GB; expandable to 64 GB as VM workload density increases. You're not locked into the base SKU's RAM configuration permanently.
• Web-Managed Interface: VLAN, QoS, PoE scheduling, and port mirroring all accessible via browser — no serial console required for day-to-day operations, which matters for IT generalists managing surveillance infrastructure.
• VM-Capable Edge Appliance: Running a VMS, NVR software, or analytics engine directly on the switch eliminates a separate compute appliance in small-to-medium deployments — fewer failure points, simpler cabling, lower rack unit consumption.

Frequently Asked Questions

Q: How many PoE ports does the QGD-1602P-C3558-8G-US have, and what are their wattage limits?

A: The QGD-1602P-C3558-8G-US has 16 total PoE ports: 4 ports support IEEE 802.3bt PoE++ at up to 90W each, and 12 ports support IEEE 802.3at PoE+ at up to 30W each. Total PoE budget is 90W aggregate — plan your camera and device load accordingly.

Q: Can the QGD-1602P-C3558-8G-US actually run virtual machines, and what's the RAM ceiling?

A: Yes. The unit is built around an 8-core Intel Atom C3558 processor and ships with 8 GB RAM, expandable to a maximum of 64 GB. This allows VMs — including VMS software, analytics engines, or network services — to run directly on the switch, eliminating a separate compute appliance at the edge.

Q: What are the uplink options on the QGD-1602P-C3558-8G-US?

A: Two 10GbE SFP+ ports serve as uplinks. At 10G, these prevent the uplink from bottlenecking when multiple 2.5GbE access ports are active simultaneously, and they connect cleanly to 10G-capable NAS units or core switches.

Q: What is the internal switching bandwidth, and does it matter for camera deployments?

A: The QGD-1602P-C3558-8G-US has 20 Gbps of internal bandwidth capacity. For deployments with 16 active PoE ports streaming video, non-blocking bandwidth prevents throughput degradation during burst events — such as simultaneous alarm-triggered recording across all channels.

Q: How is the QGD-1602P-C3558-8G-US managed — does it require CLI expertise?

A: Management is web-based. VLAN configuration, PoE scheduling, QoS, and port mirroring are all accessible through a browser interface without CLI access, making it deployable by IT generalists managing surveillance or mixed-use networks.

The QGD-1602P-C3558-8G-US is one of the few switches I'd recommend when someone needs PoE delivery and edge compute in a single 1U footprint. The 8-core Atom C3558 with 64 GB RAM ceiling isn't marketing language — it means you can actually run a lightweight VMS or NVR container on this device and skip the dedicated compute appliance entirely in a branch or retail location. That's a real architectural simplification, not just a checkbox feature.

Technical Highlights:

• 4-Port 90W PoE++: IEEE 802.3bt compliance on 4 ports means PTZ cameras and multi-sensor panoramics that need 60–90W can draw full power without an injector — most PoE+ switches top out at 30W and force an external power supply on those devices.
• 20 Gbps Internal Bandwidth: With 8 x 2.5GbE access ports potentially running at full speed, you need switching capacity that doesn't collapse under load. At 20 Gbps, this switch handles simultaneous full-bitrate streams across all ports without per-port throttling.
• Dual 10GbE SFP+ Uplinks: Connecting to a QNAP NAS over 10GbE uplink keeps recorded video off the access-tier ports entirely — camera traffic and storage traffic use separate physical paths, which eliminates a common source of dropped frames in high-channel-count deployments.

Deployment Considerations:

• The 90W aggregate PoE budget applies across all 16 ports — not per-port. If you populate all four 90W-capable ports with 90W devices simultaneously, you've consumed the entire budget. Do the per-port math before you finalize your camera selection list.
• The unit ships with 8 GB RAM (the -8G suffix in the SKU); if your VM workload needs more headroom, confirm RAM expansion compatibility with QNAP before purchase — the 64 GB ceiling requires compatible DIMMs, not just any DDR4.

This switch earns its place in mid-size surveillance deployments — 8 to 16 cameras, a co-located VMS, and a 10G-connected NAS — where consolidating the edge compute onto the switch eliminates a server, simplifies the rack, and reduces cabling complexity without sacrificing throughput.
