What the show interface ethernet <port-id> transceiver detail command actually reports? what's about logs when you hot-plugged the SFP+ Transceiver? is the transceiver HPE Aruba original? Is hopefully your Aruba 5406R zl2 Switch running a software version newer than KB.15.17.0003?
Edit 1: on my first reply confused J9151 with J9150 for which the E Revision doesn't exist at all.
Edit 2: J9151E was released also to overcome an issue on the Aruba 8325 when equipped with J9151A/D, see the reason here.
