Ruckus ICX 7150 with R510 AP seems unstable

[kc_luchsinger]

I've had this installed now for about a year without issue, but in the last few months it seems to have destabilized.  The R510 seems to occasionally switch off and reboot, and the switch will occasionally lose all communications with the rest of the network, requiring a hard reboot of the switch to get it to start communicating again.  The AP is running PoE, but I've checked the PoE allowance, and there is power to spare, so I'm not over-taxing the PoE allotment, and Spanning-tree is on so it should eliminate loop-backs. 

This is a sporadic problem, so it's hard to trouble shoot (it rarely fails when I have bunches of free-time, usually when I need to leave in 5 minutes, and I'm already late), so what can I do to further find the source of this problem?

I'd check the fans in the switch.
look at the logs after reboot and if possible  check the temps.

find out is it the switch or the  R510,
it might be the R510 shorting the PPOE & locking up the switch, so really you need to separate them... even if it means thowing in another switch between them tempararaly.. even some cheap ass consumer stuff with a ppoe bridge.

I won't tell you the number of times locked up or stopped fans have thrown our kit out of wack

Hello,

 'show logging' o/p on the switch will list down any unexpected events during the problem. That might give some clue if its on the switch.


Thanks

First off, It's a 12 port 7150, which unless I'm mistaken are fanless?  That doesn't invalidate the temperature thing.  

Here's my logging report, you can see where I restarted it towards the end:
