Hi All
We worked out what the issue was.
The electrical contractor when connecting the access point connected the AP to the injector but had not connected the power cable to the injector. As they had not told us yet what port they had connected it to the AP obtained power from the switch, but only 15w of power.
They then connected the power cord to the injector, however the AP still thought it only had 15w of power avaialble.
We disabled the POE on the switch for that port and had rebooted the AP via the CLI but the AP was stuck thinking that only 15w of power was available.
In the end we just had to disconnect the AP from the injector for 5 minutes then connect it again. The AP then realised that it had an injector and was able to obtain 30W of power and be fully operational.
We have amended the install instructions for the cablers and are now working correctly.
Thanks all for your help.
