ICX7150 switches can't deliver PoE but one ICX7550 switch can

IsaacGerman — Wed, 11 Jun 2025 00:20:50 GMT

I have several devices that are not able to get PoE from switches with model ICX7150-48ZP. However, when I connect these same devices to an ICX7550-24P They are able to draw power and work normally.
These devices are B578 Edge Routers PN 201-104-P00-SB0, they are listed to be class 2 PoE devices, and I already tried limiting the power delivery on the port by both class and Watts to no avail.
Other devices such as APs are having no issues getting PoE.
Used power on all switches is well below the allocated.
The 7150 Ruckus switches are currently running version SPS08095k and the 7550 is running version GZS08095g.
I'm running out of ideas, any advice would be helpful
