Test Light – Meaning When an access point, whether connected directly to the controller or connected via the network, displays a solid orange test light, it means that the Access Point is not able to finish it’s boot sequence. There are many reasons that could cause this, but mainly it is because the access point is not able to receive the minimum of information it requires to finish the boot procedure. This application note will address the most common causes for this condition and how to recover from it.

- More than 16 Access Points configured per Wireless Controller Each controller can only control 16 (sixteen) access points. If more than sixteen access points are connected, the controller will not provision the additional access points, which results in a test light on the unprovisioned access point(s). If a provisioned access point is removed from network, an unprovisioned access point can then be provisioned.

Appendix: AP Boot Sequence These steps describe the booting procedure of each Access Point from the moment they’re powered on until they’re ready to either be provisioned, or ready to transmit and receive. The procedure is slightly different when the APs are configured statically and dynamically, as dynamically they must discover all their communication variables, while statically they just have to load them from their own memory. Dynamic: 1. AP loads location ID from BootROM. 2.
PAGE 5
Static: These steps will be followed if the Access Points were previously statically programmed with at least an LMS IP (Local Master Switch, the wireless controller IP). 1. AP loads variables from BootROM. 2. AP sends message to the wireless controller with it’s location ID. If the Access point is unable to reach the wireless controller, it will continue to try to send the same message until it contacts the WFS709TP. 3.
