Ruckus 7372 not turning on with properly rated AC adapter?

I have a Ruckus 7372. Can't seem to get it to turn on using any AC adapters I have. The label on the back says 12V-1A... Well, 12V-1A doesn't work, 12V-1.6A doesn't work... does it need something beefier? I have a 12V-20A bench supply that it does work with. Just confused since the label on it says 1A and it definitely seems to need more.

Tech specs says
• DC Input: 12 VDC 1.0A • Power over Ethernet 802.3 af

which would imply the it'll draw a maximum of 15.4W
Have you a POE switch handy by any chance?

Adaptor (or 2) problem? Or have you already eliminated that?

I don't have a PoE switch which is why I was using the adapter. Both the 1A and 1.6A AC adapters I have work fine for other things. Putting an ammeter in line with the AP I don't see anything over 1A when this thing is starting to when the radios turn no, so I'm not sure what the deal is. Maybe it's a short surge initially that I'm not seeing.

Possibly irrelevent/stupid but the poles of the adaptors are reversed by any chance?

Checked it, we're good there on the polarity.

Getting very close to point where I'd call tech support and ask them for tshooting help and then a replacement unit.

Except since this is an EOL unit you are unlikely to be warranted on this thing.

Yep my thoughts exactly. Oh well, unfortunately it's looking like it's going into the trash bin.

I spent $39 at Fry's for a 4 x 100mb PoE switch, with 5th port uplink.
I'd test the PoE too, and try TS anyway if you bought it from us/our VAR
(not second hand).  We provide a lifetime limited warranty for ZoneFlex
products (but testing with non-Ruckus power adapters, especially over
1amp, would void it...).  A 7372 under support would probably get an
R500 replacement unit.

This was an electronics recycling bin find, so no worries on warranty. Just wondered if anyone else had the same issue more or less.
