Every panel among 24-port patch panel can install 1 keystone jack.
It allows the keystone jack on the patch panel to match with the number of twisted pairs and no keystone jacks even installed into the other module holes will not affect the exterior design.
The dust covers on the frame can select different colors.
Everyone knows that the number of colors of STP module is always very few, generally silver white only. It is hardly possible to distinguish inner network, secret-involved network, “red” telephone, etc as per colors of STP modules. However, the change of dust cover colors can tell users the networks to which keystone jack belong in the most intuitive manner.
There are organic glass label boxes at the top of the panel; 24 panels are installed on the distribution frame, so there are 24 independent label boxes.
