Yeh - it's just the Arubas are much more sensitive to slightly dodgy connections. Connections and wiring which worked with their predecessor Ciscos just fine is persona non Grata in the Aruba universe.

With cameras they just won't talk to them even if the port is set to 10mbps rather than Auto. Stick an unmanaged switch in the way and they work fine.

One thing I have found is that FS.com sfp+ Aruba compatible modules work just fine which saves a packet!
