Highlights
- Four-port Gigabit PoE room cable hub that centralizes power and connectivity for room cameras, microphones, and speakers.
- E2 edition disables Energy Efficient Ethernet (EEE) and adds QoS, which is required for Yealink CM20, CS10, and Dante devices.
- Up to 30 W per port and a 90 W total PoE budget, 802.3af/at compliant.
- Yealink EasyConnect allows connection to a Yealink VCH port without a separate power adapter.
- Yealink SafeConnect applies PoE priority, shutting down low-priority devices first when demand exceeds the budget.
- Compact 100 mm x 100 mm x 23 mm form factor for in-room mounting.
- Two-year hardware warranty.
Ideal For
- Yealink room systems adding CM20 ceiling microphones or CS10 ceiling speakers
- Medium and large rooms consolidating multiple PoE AV endpoints on one hub
- Dante-based room audio requiring EEE disabled for stable operation
- Deployments reducing power supplies and outlet dependence at the table or ceiling
- Standardized Yealink room builds specifying a consistent room cable hub

Yealink RCH40 E2 Room Cable Hub, 4-Port PoE Switch for CM20 and CS10 (1303166)
The RCH40 E2 is a compact four-port Gigabit PoE room cable hub that consolidates the power and network connections for a room's cameras, microphones, and speakers into a single device. It provides up to 30 W per port within a 90 W total PoE budget, so several professional AV endpoints can run over standard Ethernet from one location, reducing the number of power supplies and outlets a room otherwise needs.
The E2 edition exists for a specific reason. Yealink builds the RCH40 in two versions, and only the E2 disables Energy Efficient Ethernet (EEE) and adds QoS. Yealink CM20 ceiling microphones, CS10 ceiling speakers, and Dante devices require the E2 because of that EEE-disabled requirement, so this is the correct hub to specify whenever those devices are in the room. Before ordering, confirm the room uses CM20, CS10, or Dante endpoints (which mandate the E2 rather than the standard RCH40), total the PoE draw of the connected devices against the 90 W budget, and decide whether to use EasyConnect from a Yealink VCH port or the included power adapter.

Certifications and Compatibility
- Yealink CM20 ceiling microphone: requires the RCH40 E2 due to the EEE-disabled requirement.
- Yealink CS10 ceiling speaker: requires the RCH40 E2 due to the EEE-disabled requirement.
- Dante devices: require the RCH40 E2 for stable operation with EEE disabled.
- Yealink room systems: connects to a Yealink VCH port using EasyConnect, or operates with its own power adapter.
- Standard RCH40 versus E2: the standard RCH40 does not disable EEE and is not suitable for CM20, CS10, or Dante. Specify the E2 (this SKU) for those devices.
- PoE budget: confirm the combined draw of connected devices stays within the 90 W total and 30 W per-port limits.
Design Considerations
- Specify the E2, not the standard RCH40, any time CM20, CS10, or Dante devices are in the room. The editions look similar but only the E2 disables EEE.
- Total the PoE draw of all connected endpoints and keep it within the 90 W budget, allowing for per-port limits of 30 W.
- Decide the power method during design. EasyConnect from a Yealink VCH port removes the need for the power adapter, while a standalone deployment uses the included adapter.
- Use SafeConnect priority to protect critical devices, such as a camera, when the room's total PoE demand approaches the budget.
- Plan cable runs from the hub to ceiling microphones and speakers using CAT5e or better.
Licensing, Warranty & Support
No license or subscription applies to the RCH40 E2. It is covered by Yealink's two-year limited hardware warranty, with terms available from Yealink or an authorized reseller at the time of purchase. Firmware and configuration, where applicable, are handled through the Yealink room system and Yealink's management tools.
VideoConferenceGear.com Assistance
We can confirm the RCH40 E2 is the correct hub for your room, which it is whenever CM20, CS10, or Dante devices are involved, and verify that the combined PoE draw of your cameras, microphones, and speakers fits within the 90 W budget. We can help you decide between EasyConnect from a Yealink VCH port and standalone power, plan SafeConnect priorities so critical devices stay online, and standardize the room cable hub across a multi-room or multi-site rollout so every space is wired and powered the same way.
Common Questions
What is the difference between the RCH40 and the RCH40 E2?
Both are four-port PoE room cable hubs. The E2 adds QoS and disables Energy Efficient Ethernet (EEE). Yealink CM20, CS10, and Dante devices require the E2 because of the EEE-disabled requirement.
Which SKU do I need for CM20 or CS10?
The RCH40 E2, which is this SKU (1303166). The standard RCH40 is not suitable for CM20, CS10, or Dante.
How much power does it provide?
Up to 30 W per port within a 90 W total PoE budget, 802.3af/at compliant.
Does it need its own power supply?
Not always. With Yealink EasyConnect it can connect to a Yealink VCH port without the power adapter. The included adapter is used for standalone deployments.
What happens if connected devices need more power than the budget?
Yealink SafeConnect applies PoE priority and shuts down low-priority devices before high-priority ones, keeping critical endpoints online.
