I just spent a good half hour trying to find out why an uplink to a 2nd location was not working after unplugging the network equipment very briefly due to UPS swapping .. Seems like I had failed to save configuration on my Zyxel GS 1920 backbone switch .. Having Link Aggregation on ports 25-28 when you only need 25,27 because 26 and 28 now go to a different building and server is definitely never going to work ..
