A PoE++ switch (802.3bt) delivers up to 90W per port over a single Ethernet cable. This eliminates the need for separate AC power bricks for digital signage displays and thin clients. By centralising power management, it reduces installation costs, cuts cable clutter, and simplifies remote monitoring. WECENT supplies original, warrantied PoE++ switches from Cisco, H3C, and Huawei – ideal for enterprise deployments.

What Is PoE++ and How Does It Differ from Previous Power-over-Ethernet Standards?
Power over Ethernet Plus Plus (PoE++) is defined by IEEE 802.3bt, offering two types: Type 3 delivers up to 60W per port, and Type 4 up to 90W. It is backward compatible with 802.3af (15.4W) and 802.3at (30W). Thin clients typically require 30–90W, while digital signage displays often need 60–90W – making PoE++ the ideal power source.
For reliable 90W delivery, Cat6a or higher cabling is recommended to minimise power loss over distances up to 100 metres. Lower-grade cables may overheat or suffer voltage drop at maximum power.
| Standard | Max Power per Port | Typical Devices | Recommended Cable Grade |
|---|---|---|---|
| 802.3af (PoE) | 15.4W | IP phones, basic sensors | Cat5e |
| 802.3at (PoE+) | 30W | IP cameras, wireless APs | Cat5e |
| 802.3bt Type 3 (PoE++) | 60W | Small signage, thin clients | Cat6a |
| 802.3bt Type 4 (PoE++) | 90W | Large signage, workstation thin clients | Cat6a or higher |
Why Replace Traditional Power Bricks with a Single Ethernet Cable in Thin Client and Signage Deployments?
Eliminating AC adapters reduces installation labour, material costs, and cable clutter. No need for dedicated power outlets at each device location – one Ethernet cable handles both data and power. Centralised power management via SNMP enables remote monitoring, scheduling, and reboot of all endpoints, reducing site visits.
A single UPS at the switch protects every connected device, drastically improving reliability compared to dozens of individual power bricks. Scalability improves too: adding or relocating a thin client or sign merely requires a cable run, not an electrician. This flexibility is especially valuable in dynamic retail, education, and healthcare environments where layouts change frequently.
Which PoE++ Switches Are Compatible with Enterprise Thin Clients and Digital Signage?
Any 802.3bt-compliant switch can power PoE++-capable endpoints. WECENT supplies original PoE++ switches from Cisco, H3C, and Huawei – all carrying full manufacturer warranties. Port counts range from 8 to 48 ports, with total power budgets that must match your deployment. For example, a switch with 740W total budget can support 8 devices at 90W or 12 at 60W, with headroom for safety.
Compatibility extends to most enterprise thin clients that support optional PoE modules (e.g., many models from Dell, HP, and Lenovo) and digital signage players that accept 802.3bt. WECENT’s engineers can verify device compatibility during the selection process, ensuring seamless integration with your existing network infrastructure.
How to Choose the Right PoE++ Switch for Your Thin Client and Signage Network?
First, calculate the total power draw of all connected devices at peak consumption, then add at least 20% headroom for safety and future expansion. Next, consider port count: a 24-port switch may suit a small signage network, while a 48-port model fits larger campuses. Uplink speed matters – 10GbE is recommended for backbone connectivity, especially when streaming high-resolution content.

Management features such as VLAN support, PoE scheduling, and energy-efficient Ethernet (EEE) enhance control and reduce operational costs. Physical environment also matters: office deployments may require fanless switches, while data centers can tolerate higher noise levels. WECENT’s team can help match your power budget, port density, and management needs to the exact switch model from Cisco, H3C, or Huawei.
WECENT Expert Views: “With over 8 years of enterprise PoE++ deployments, we recommend always selecting a switch with at least 30% spare power budget. This buffer accommodates future upgrades – for example, upgrading a thin client to a higher-power model or adding edge AI modules. Our engineers typically audit the existing network, measure real-time power draw of each endpoint, and then propose a switch with adequate headroom. We also advise using Cat6a cabling for all 90W runs to avoid voltage drop issues. Whether you need a standalone switch or a bundle with Dell PowerEdge servers and NVIDIA GPUs for GPU-accelerated signage, WECENT delivers tested, warrantied solutions.”
Does PoE++ Integrate Seamlessly with Enterprise Servers and GPU-Accelerated Signage?
Yes. PoE++ endpoints connect to the network, which in turn connects to backend servers such as Dell PowerEdge Gen 14 through Gen 17 models. These servers handle virtual desktop infrastructure (VDI) or content management – no separate power conditioning is needed. For AI-driven signage (real-time analytics, facial recognition), thin clients can access GPU power from central servers like the Dell XE9680 (with H100, H200, or B200 GPUs) or XE7740 via virtual desktops.
WECENT’s full GPU spectrum – from GeForce RTX 40/50 series for edge inference to Quadro RTX A Series for professional rendering to Data Center H100/B200 for large-scale AI – enables flexible compute placement. You can run inference at the edge on a PoE++-fed thin client, or deliver GPU-accelerated graphics from a data center. The PoE++ network infrastructure remains constant, while backend compute scales as needed.
What Is the Total Cost of Ownership (TCO) Advantage of PoE++ over Traditional Power Bricks?
Upfront savings come from fewer AC outlets, no need to purchase and manage hundreds of power bricks, and lower installation labour – network technicians can run cables instead of hiring electricians for each drop. Operational savings include centralised UPS: one battery backup at the switch protects all endpoints, rather than individual UPS units per sign or thin client.
Remote power management reduces site visits for rebooting or troubleshooting – a single SNMP command can power-cycle any port. Equipment lifespan is favourable: a quality PoE++ switch typically outlasts two or three generations of end devices. WECENT provides lifecycle support and replacement parts for 3–5 years, ensuring your TCO remains predictable and low.

Frequently Asked Questions
Can I use a standard Cat5e cable with PoE++ 90W?
For 90W Type 4, Cat6a or higher is recommended to avoid overheating and voltage drop. Cat5e can handle up to 60W at short distances but is not reliable for 90W.
What thin client brands support PoE++?
Most enterprise thin clients that support an optional PoE module are 802.3bt-compatible. Check device specifications for “PoE++” or “Power over Ethernet 60W/90W” support before deployment.
How many PoE++ devices can a 24-port switch power at 90W each?
It depends on total power budget. A typical 24-port PoE++ switch may have a total budget of 740W – enough for 8 devices at 90W (8×90=720W) plus headroom. Always verify the PSU rating of your specific switch model.
Does WECENT offer PoE++ switch + server bundle discounts?
Yes. As an authorized agent, WECENT provides custom quotes for bundled solutions – for example, a Cisco Catalyst switch combined with a Dell PowerEdge server and NVIDIA GPU – with volume pricing for wholesalers and system integrators.
What is the warranty on PoE++ switches from WECENT?
All switches carry the original manufacturer’s warranty (typically 3–5 years). WECENT also offers extended service contracts and advance replacement options for enterprise clients.
