To ensure proper operation when installing the switch into a network, make sure
that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T
operation. Check the following criteria against the current installation of your
network:
◆ Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP)
cables with RJ-45 connectors; Category 3 or better for 10BASE-T, Category
5 or better for 100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.
◆ Protection from radio frequency interference emissions
◆ Electrical surge suppression
