      Hi there!

      Bought a SG-3100 recently, and I've been experiencing the router power cycles randomly from time to time.

      From Troubleshooting Unexpected Reboots

      • I haven't had (on reboot) a prompt to view & submit a crash report.
      • System logs haven't indicated any sort of panic (by searching for "panic").
      • Piped syslogs indicate nothing's awry before the restart.
      • It takes about ~3 minutes to fully restart.
      • Temperatures have hovered around ~65C.

      Anything that I could do to narrow down the issue to any particular hardware component?

        particular hardware component

        If the "power cycles" then there will be no log lines that might explain the reboot. The system just dies. And a stopped system can't log.
        The only log lines related to the event are the startup messages of the system/kernel, etc.

        If possible, swap the power brick (do respect type of plug, tension and polarity, and the minimum number of amps).
        Add a UPS in front of the power brick, and link the UPS to pfSense using a USB cable. With the NUT package you can set up pfSense to do a clean power down when the power fails.

        Also, connect to the console, and execute some file checks. See manual for the how-to. pfSense is like a Mac or Windows PC : if the power stops like that, the file system could be messy. it should be cleaned.

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

            That's what I feared, unfortunately.

            The router is currently contained in a in-wall media closet with limited space (roughly a foot by a foot), and I was hoping to get some other indicators before going this path. Haven't found any UPSes that have played nicely, but high hopes on the unit coming in shortly.

            Also, connect to the console, and execute some file checks. See manual for the how-to. pfSense is like a Mac or Windows PC : if the power stops like that, the file system could be messy. it should be cleaned.

            Home network.

              @marked The router overheats, and does thernal shutdowns.
              65 is way too high and having active equipment in small closets is a recipe for disaster/fire.

                Would this emit a log line then? If not, how about a setting?

                I've seen various posts on the internet (#1, #2, #3, #4, #5) that indicate the temperature range still falls within "okay."

                  No, not necessarily. 65 is a lot and will put extra strains on critical components leading into permanent failure soon.
                  You don't know what exactly fails due to high temp, and logging such issues is often impossible without specialized hardware.
                  Open/remove the closet door, and see how the temperature drops.

                  As a fact anything over 50 is consider problematic, no matter what the specs say.

                    Do you mean the temp on the Dashboard?
                    The SG-3100 measure the CPU Core temp directly, about 60-70°C it is normal, no worry about.
                    The Marvell Armada 38x max Temp is 115°C, have a look at the Hardware Specifications Point 9.1 Page 104:
                    HW Spac

                    My SG-3100 run stable with 2.4.5, but som times i run with pfblockerng into the large tabel bug.
                    It will be fixes bei 2.4.5p1, looks like it released shortly.

                    Whitch version you run and which packeges do you use?

                      Yes, I do. Thanks for the information.

                      Packages wise, nothing too intense right now.

                      acme	                0.6.8	  
                      Avahi	                2.1_1	  
                      Cron	                0.3.7_3	 
                      haproxy-devel	        0.60_4	  
                      ntopng	                0.8.13_5	 
                      pimd	                0.0.2	 
                      Status_Traffic_Totals	2.3.1	 
                      sudo	                0.3_2	  
                      

                      Plugged in a UPS for the router, hoping that it resolves the issues.

                        Not intense. Just crushing.
                        A couple of days ago, just this package brought a big, brand new system to a halt in a day or so ....

                          Hmm. Definitely not ideal.

                          I've put a UPS in between my router and the outlet, kept the packages the same, upgraded to 2.4.5-p1, and haven't suffered from any downtime. I'm going to chalk this issue up to intermittent power issues.

                          Thanks all, for chiming in.

                              Just to confirm that is a completely normal value for the on-die sensor in the SG-3100.

                                I use a lot of PC Engines APU2D4 which has an AMD GX-412TC 1Ghz CPU, 4GB DDR3-1333 soldered memory, supports AES-NI, (3) I210 ethernet ports. These boxes run notoriously hot. The worst I've seen (hot environment) is it chugging along at 71C (159F?) with no problem. In a cool environment the box still runs at 50C.
