Cisco 9124AXE Power Requirements

Depending on the configuration you intend to run the Cisco 9124AXE in, you’ll likely need a switch which supports UPOE (60w).

Many switches are not capable of this POE requirement, so you are left with a choice: an expensive switch replacement, or the use of a power injector.

The image below details the official Cisco power injector for the 9124AXE, noting there are additional third-party manufacturer options:

There are some important notes for powering the 9124AXE AP:

  • To enable both 2.4GHz and 5GHz (Dual Band) on all 4 ports the Access Point must be powered by UPoE (60W / 802.3bt)
  • When ports 5 and 6 are also connected to an antenna, the Access Point must be powered by UPoE (60W / 802.3bt)
  • If UPoE (60W / 802.3bt) is not available on the switch port connecting the Access Point, we can use a “Power Injector”
  • The AIR-PWRINJ-60RGD2 Power Injector is shown here, and can be wall mounted, or pole mounted

 Summary

If your switch doesn’t provide enough PoE power, a power injector like the AIR-PWRINJ-60RGD2 is essential to fully utilise the Cisco 9124AXE.

When designing your Wi-Fi installation, it is important to consider the POE budget on your switches, so you don’t discover a sudden need to provide more power than the switch can deliver.

This is true for the power-per-port, as well as the overall concurrent power, so consider this when adding POE devices to the network.
