It really shouldn't be a problem, though can be, equipment's power supplies should be able to ride out that kind of thing. Older equipment's power supplies may not be as good as they used to be. >> If you can't find the cause, perhaps a UPS is in order. > I called out an APC BX1500M. It has been in place all this time.

I've had to replace network switches a few times when they spanned between buildings. You could see the LEDs on one of the ports madly blinking when it got damaged (see: "flapping"). Power cycling it would reset things back to normal, but over time failures became permanent. Outside network cabling is vulnerable to things like somewhat-near lighting, and wind blowing over it causing hight static electricity voltages. And you can have mains wiring problems between buildings, within a building, or even within a room (if it spans a phase) cause problems with equipment joined together by network cabling. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
