The RUCKUS ICX 7150-C12P is a compact switch that supports Power over Ethernet Plus (PoE+), compliant with the IEEE 802.3at standard. This standard specifies a maximum power delivery of 30W per port from the Power Sourcing Equipment (PSE). The other listed models (ICX7650, ICX7550, and ICX7150-48ZP) all support higher power standards such as IEEE 802.3bt or Power over HDBaseT (PoH), which allow them to deliver up to 90W per port, thus exceeding the 30W limit.

A. ICX7650: This model supports Power over HDBaseT (PoH), which can deliver up to 90W per port, far exceeding the 30W maximum.

B. ICX7550: This switch series includes models that support the IEEE 802.3bt standard, enabling power delivery of up to 90W on dedicated ports.

C. ICX7150-48ZP: This specific model is a Z-series switch that supports IEEE 802.3bt (PoH), providing up to 90W per port to power high-power devices.

1. RUCKUS ICX 7150 Family Data Sheet. In the "RUCKUS ICX 7150 Switch Models" table, the ICX 7150-C12P is listed with "12× 10/100/1000 Mbps PoE+ ports". The ICX 7150-48ZP is listed with "16× 10/100/1000/2500 Mbps 802.3at/bt (PoH) ports". This document confirms the ICX7150-C12P is limited to PoE+ (30W) while the ICX7150-48ZP supports 802.3bt (up to 90W). (Document available via the official CommScope/RUCKUS website).

2. RUCKUS ICX 7650 Switch Data Sheet. Under "Product Highlights," it states, "Power over HDBaseT (PoH) up to 90 watts per port and IEEE 802.3bt ready, PoE/PoE+." This confirms its ability to exceed 30W per port. (Document available via the official CommScope/RUCKUS website).

3. RUCKUS ICX 7550 Switch Series Data Sheet. The "At a Glance" section specifies, "802.3bt (90W) PoE on dedicated ports to power next generation wireless APs and IoT devices." This confirms its capability to exceed 30W per port. (Document available via the official CommScope/RUCKUS website).
