I've had a about a 5% failure rate for two batches of AP-315 that I purchased in late 2017 and early 2018. I'm hoping it was just a temporary production issue rather than a design problem, but I haven't really had much useful data on it from HP/Aruba. (They are very good about sending out replacement units, but I'd like to know the scale of the issue.)
Apparently the problem is the ethernet jack (en0) snaps off the motherboard. I'm assuming its cold solder or something, but I've never opened the AP to look at it.
In my most recent example, the new-from-the-box AP was fine when I configured it on my desk, and fine when I first plugged it in out in the field, but as I snapped it onto the plastic T-rail mounting clip, both LEDs blinked out, and the AP was dead. It would no longer power up from POE, and when I connected it to a power adapter and used the console cable, I could see it boot, but then never get a DHCP address on en0.
These symptoms are consistent with the Ethernet jack being physically disconnected from the motherboard. (That's the anaylsis that support gave me after I RMA'd my 5th one and explicitly asked what was going on!)
So, with this AP, just the minor "snap" of clicking the AP into its bracket was enough to break loose the port.
Anyway, anyone else having excessive failures of AP-315?
I'm hoping it is a production problem and has been resolved, but again, no answers from HP/Aruba. Except for the fragile ports, seems a good AP.
Cheers,
Steve
