Correct power supply for Cisco Aironet PoE injector

[rmiller]

I have a Cisco Aironet Power Injector p/n AIR-PWRINJ3. I am wondering if a power supply I have here is compatible. It is p/n AIR-PWR-C. It looks like they're both 48V so I'm guessing it's okay but thought I should confirm before connecting it to my AP.

PWRINJ-3 requires a power brick. This brick is usually the AIR-PWR-C.
So depending on your AP, it should work.

Do you know if this would be compatible with a Meraki MR33?

You need to understand the PoE requirements for the specific AP you want to power. If the AP requires 802.3at power, then any power injector that supports 802.3at will work.

Unless it's a Cisco power injector. They tend to block other companies products and only work with Cisco APs. But you can safely test if it works.
