Hi, TL;DR: It's not strictly necessary to ground the entire rack, but you should consider doing so for safety and proper operation. The forums you read suggest grounding to protect components and avoid electrical hazards, especially since the cables run through potentially exposed areas. Even if you don’t use the rack for networking, keeping everything grounded helps prevent damage and ensures reliable performance. Research shows that proper grounding is important regardless of where the equipment sits.
If the devices you put in the rack have ground plugs they'll pop the breaker if live ever shorts to ground. Where you might like to make your own ground is when a device that take 240AC in doesn't have a ground. If that shorted to the case that could get shorted to the rack and suddenly you have a rack that's live at mains voltage. Luckily most basic small port network switches run off low voltage DC and most high end networking equipment is grounded. Unless you're looking to protect from an external force like a lightning strike there's no overwhelming reason to do this.
When the outer casing is metal, it must be connected to ground according to local electrical standards. Grounding becomes essential only when the device housing is insulated, such as plastic. Metal conducts electricity, so many gadgets use the metal frame as a kind of reference point. To ensure safety, connect it to the actual ground wire. Without this connection, static charges build up inside and can cause shocks if you touch it or damage the equipment. Some setups omit a dedicated ground wire, relying instead on the service panel’s neutral for safety. Ground wires are meant to handle fault currents, like when a wire gets damaged and shorts to metal. Without proper grounding, the risk of electric shock increases significantly.
You're asking if you don't need to worry about grounding for your setup. Based on the information you shared, it seems you're on the right track. The manual suggests you won't have to worry about grounding with this configuration. Regarding the patch panel, it likely includes a ground wire for safety and stability, even though it's passive. It's there to ensure proper operation, not to carry voltage. Let me know if you need more clarification!
Beyond local rules, if they don’t require it, I wouldn’t be concerned. Your gear should have its own dedicated area. I own a switch almost identical, with its own ground connection. This is likely where we address lightning or electrical issues. You don’t want high-voltage AC or other discharges entering low-voltage DC cables and reaching sensitive networking devices. It makes sense to connect the chassis to ground through the patch panel anchor on the back. If this matters, it’s fine—it won’t cause any harm.
It includes a built-in connection to the wall. You can observe it in videos when he removes the power plug. Three prongs are used. These aren't completely passive; the cables can handle small voltages during normal use, typically between 0V and +-2.5V—very low but present. Power over Ethernet exists with the right equipment and cables. https://en.wikipedia.org/wiki/Power_over_Ethernet Still unsure if the devices you're viewing support it, but generally the ground is meant for external issues like lightning rather than the Ethernet switch itself. If you're using a TP-link switch, don't worry about these details.
I didn't realize I could simply ground the patch panel through the switch, but it really makes sense. Thanks a lot to both of you!
