10Gbit switch earthing configuration
10Gbit switch earthing configuration
It’s generally safe to connect the earth point directly to the mains earth, especially since your power supply is isolated. Just ensure proper grounding at the chassis is in place. It’s not necessarily a problem if you haven’t earthed it yet—just confirm the setup meets local safety standards.
I mean honestly unless you're hoping to protect the chassis being struck by lightning or mains voltage there's no a whole lot of point to it. I suppose of you're really worried about ESD you could ground it. I've looked at those myself and the only earth I can think of to screw it to is the ground found in an electrical outlet.
It would be simple enough to remove a wire from the outlet, perhaps using IEC adapters that can take over a ground connection from the NAS power cable. (I’m a bit skeptical about that idea since I’ve heard some UPS units cut the ground when running on battery.) I could just mount it directly onto the NAS chassis, though I’m worried I might lose track of it during my next cleaning session and end up pulling the whole switch down.
The dual ISP setup appears to be functioning through bridged connections.
I just recovered a very vague recollection. I think those ground screw terminals are meant for connecting earth from an un-earthing device to one that is earthed. Imagine two switches: one uses the earth lead on the plug, the other doesn’t, but both have the earth lug on the back. You can still get a ground through the device with the earth lead. Also remember what people say.
ISPs are assigning the same tier rating in pfSense, which seems to enable a fair rotation. I’d like to pair them properly, but I’m only familiar with one UK provider that offers this and they charge a high monthly fee with usage limits, unlike most competitors that have no restrictions. I only have specific clients on the network using both, and I haven’t seen any tools linking user sessions to IP addresses anymore—everything appears to function smoothly. My bank doesn’t seem concerned either. FTTP is arriving in my area, so I expect it will replace it entirely within a few years with significantly faster speeds at a comparable cost. Can’t wait!
I wasn't aware of STP cables, even though I use a pair on one of my servers. I didn't notice if the switches have RJ-45 ports with metal enclosures but missing ground pins—something I missed.
