5800-48G-POE+ fails to recognize non-HP 802.3at device(s)

5800-48G-POE+ fails to recognize non-HP 802.3at device(s)

I have a 5800-48G-POE+ running 5.20.105 R1808P17 code and feeding three downstream NJ2000s, a Cisco 2960CPD,  a Brocade ICX6450-C, two Aruba AP105s and two Cisco 7970s.


The 5800 passes POE+ (802.3at) power to the NJ2000s because I can run another Aruba AP105 or Axis camera off them.


The 2960CPD will boot with just a single 802.3af but would need two 802.3af feeds or one 802.3at feed to pass power on.


The ICX6450-C needs one 802.3at or two 802.3af to boot. To pass power would require a second 802.3at.


For some reason, the 5800 will not regconize either device as supporting 802.3at but does see them as Class 4. The switch itself is only passing on a peak of 71 watts with 370 watts available for use so it's not a capacity problem.


Has anyone seen this before or know how to force the switch to acknowledge a remote device as 802.3at?
