Frequently Asked Questions
Why should I use dust covers on my Ethernet ports?
Dust covers prevent dirt and debris from entering unused ports which can degrade signal quality. They also protect contacts from oxidation and physical damage over time ensuring reliable connections.
Do dust covers affect network performance when installed?
