We have our hands on one PMP450v AP and some PMP450v 4X4 SMs and we are working on getting familiar with them. Some of the behavior when we configure carriers and component carriers seems a little odd. The equipment isn’t connected to any network and we’re not trying to involve an AFC yet. We’re just using the AP and SM on the floor in our office and trying to get the SM to register with the AP. We’re also involving a PMP450i and trying to get it to register with the AP.
The good news - we were able to successfully register the 450v SM on the AP, with carrier aggregation on two 20 MHz component carriers within one 5.7 GHz carrier. The 450i was also able to register on one of the CCs at the same time. 
The challenging part - there were many times during testing when neither SM could register on the AP. The SM’s AP Evaluation tools weren’t able to detect any beacon. When this occurred we reset everything by putting the CC settings on the AP to None. Then we reconfigured and reactivated the same carrier and CC settings. The SMs always found the beacon and registered right away after we did this reset. It seemed like the order that we did things mattered. It looked like there were times when the AP was not broadcasting the beacon, but at other times, with the exact same configuration when the beacon was being detected by both SMs.
Am I missing something? Is there any documentation that provides more detail on component carriers than there is in the configuration guide? Has anyone else noticed anything similar to what I described?
Thanks
