Rebooting problem with RB532 APs

Thanks for this forum. I see a lot of helpful people here, and I will appreciate any help I can get. I have two RB532 APs that are working great, except they reboot (both at the same time, assuming the CPE up times on the reg list are an indication of that) on their own. The longest up times I have seen is 1 hour 6 minutes. They both lose their log records as well. I’m running all my tower gear on a UPS, so I don’t think it is a power issue, but cannot be 100% sure without some kind of monitoring/recording device, which I don’t know where to get at this time. Anyone out there had a similar problem? The fact that they both do it simultaneously makes power very suspect. Is MT gear especially sensitive to power glitches? I never saw this with my old SmartBridges APs, which I’m phasing out (hopefully…). I’m new to MT, so it’s all pretty challenging to me. Thanks.

Update: This was discovered to be a UPS problem. For some strange reason every hour and 6 minutes the power would drop momentarily, causing a reset of up times and the clock. It was not actually a full reboot as I thought. We all trust UPSs, perhaps too much. This is my first time to get bitten by this one. Thanks to all who read my post.

Update on the Update: It wasn’t actually a UPS, it was one outlet on a remote Web-accessible power strip, which makes sense, because a UPS is too dumb to glitch exactly every hour and six minutes…
