Connecting the cable screening
When using shielded installation cables also use shielded RJ45 connectors. In this
way the shielding of the installation cables is automatically connected with the
housing of the communication server and therefore with the building earth.
Note
Connect the cable screens to one another at the splitting point only.
Observe the tree structure principle to prevent earth loops.
