Silent Fanless Access Huawei Poe Switch 16 Port S5735-L16LP2X-QA-V2 125W 159Mpps 1.2U
Huawei S5735-L16LP2X-QA-V2: Silent 16-Port PoE+ Access Switch
Zero Noise. Sixteen Ports. Enterprise Features.
Most access switches sound like small aircraft taking off. The Huawei CloudEngine S5735-L16LP2X-QA-V2 makes zero noise — because it has no fans.
This is a 16-port Gigabit PoE+ switch built for places where noise is not acceptable: hospital wards, open plan offices, retail stores, hotel corridors, and executive suites.
The PoE Budget: 125W, Smartly Distributed
Sixteen PoE+ ports. 125W total budget. Here is what that powers in the real world:
| Device Type | Power per Port | Maximum Ports |
|---|---|---|
| 802.3af (basic AP, IP phone) | ~15W | 8 ports |
| 802.3at (PTZ camera, Wi-Fi 6 AP) | ~30W | 4 ports |
The math is honest. This switch does not promise 16 full-power PoE+ ports — no 125W budget can. Instead, it gives you flexibility for mixed deployments. Power four high-demand devices plus several low-power phones. That covers most branch office and retail scenarios.
Two 10GE Uplinks: No Bottleneck
Gigabit to the desktop is standard. But your uplink cannot be the weak link.
This switch provides 2 × 10GE SFP+ ports for upstream connectivity. Aggregate traffic from 16 access ports. Connect to distribution switches. Run LACP for link redundancy. The uplinks will not be your bottleneck.
Silent by Design, Cool by Natural Convection
No fans means no moving parts. No moving parts means:
-
Zero noise — below 20 dB, essentially unmeasurable
-
No dust ingestion — fans pull dust into electronics
-
Higher reliability — fans are a common failure point
Cooling is entirely passive. Natural convection draws heat upward through the chassis. The operating range is –5°C to +45°C — sufficient for climate-controlled indoor environments.
The chassis is 1.2U tall (54 mm) and IP40 rated for dust protection.
Enterprise Software in a Quiet Package
This is not a stripped-down "quiet switch" that compromises on features. It runs the same VRP8 software as Huawei's enterprise lineup:
-
Layer 3 routing: static routes, RIP, OSPF, OSPFv3
-
VLAN features: 4K VLANs, Voice VLAN, MUX VLAN
-
Security: 802.1X, port security, DHCP Snooping
-
Interoperability: VBST (compatible with PVST/PVST+/RPVST), LNP
-
Management: cloud management via iMaster NCE-Campus, SNMP, Telemetry
Who Actually Buys This Switch?
| Use Case | Why It Fits |
|---|---|
| Hospital patient rooms | Zero noise, no fan-generated dust |
| Open office floors | No distracting fan hum |
| Retail store | 16 ports for POS + APs + cameras |
| Executive conference room | Silent operation in sensitive spaces |
| Hotel corridor access | 1.2U fits shallow enclosures |
The Bottom Line
The S5735-L16LP2X-QA-V2 solves a simple problem: how do you put a switch in a quiet room without annoying everyone? The answer is fanless design, honest PoE budgeting (125W), two 10GE uplinks, and full enterprise software features.
If silence matters, this is your switch.
