Wireless Access Points going offline after initial configuration
This can be caused if you are using a PoE enabled switch and have manually set the power on the ports to a maximum of less than a certain wattage depending on access points used. Below is a list of the APX access points and their maximum used power ratings:
- APX320 - Maximum Power: 11.5W

- APX740 - Maximum Power: 22.4W
In addition to the maximum power ratings that could be configured on the PoE switch, below are the supported PoE types:
- APX320 - PoE Requirements: 802.3af

What to do
We recommend using a separate PoE injector to see if the problem is power from the switch. If using a separate PoE injector fixes the problem, then you will need to investigate the power supplied to the unit via your PoE enabled switch and ensure it is set to a value that supports the APX device in use.
