I am unable to POE any recent model ruckus APs with a PowerDsine 9524 (this is a newer model midspan). They will power up with a PowerDsine 9024. The 9524 has no issue powering other POE devices or older model ruckus APs. I've tried over 5 different current models of AP's with no success. The PowerDsine 9524 is in a default configuration. Any suggestions?
