@urbnsr Doesn't that switch do up to 320W of POE power? I don't think 15W is enough to push the internal circuitry with its inherent passive cooling ability past it's point of needing forced air...

LOL...well, just keep in mind that the plastic cabling is subject to temp swings and aging, so a marginal crimp can fail (particularly if one used stranded connectors on solid copper cable etc.)....

ER605v1 (1.2.3beta, server) <--> ER605v1 (1.3.0, client) Both modems are bridged, so WAN ports have public IPs. Both have second WAN ports configured, but no active connection at this time. General...

@Unnamed.m3 I'm leaning more towards a marginal connector crimp, or some crude on the connector itself. It's sounds like an intermittent electrical fault to me, given that the swap seems to have...

@Unnamed.m3 Have a look at the Events under Logs in your controller. You may see something there related to the AP playing peek-a-boo.

@urbnsr It may actually just take some time to warm up enough to need the fans.... I'd running it with 20-30W of POE load for 30min...either fans kick in, or the lights go out. You'll have your...
