Sophos Wireless Access Points: APX offline after initial configuration


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
  • APX530 - Maximum Power: 16.7W
  • 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
  • APX530 - PoE Requirements: 802.3at
  • APX740 - PoE Requirements: 802.3at

This article describes the steps to resolve the issue of the access points failing to power up after initial configuration is sent to it.

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.
