Ethernet Cabling

To ensure proper operation when installing the switch into a network, make sure that the
current cables are suitable for 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) cable with RJ-
45 connectors; Category 5 or Category 5e with maximum length of 100 meters is
recommend 100BASE-TX, and Category 5e or 6 with maximum length of 100 meters is
recommend for 1000BASE-T.

•

Protection from radio frequency interference emissions.

•

Electrical surge suppression.

•

Separation of electrical wires and data based network wiring.

•

Safe connections with no damaged cables, connectors or shields.

RJ-45 Connections

SFP Transceiver

Equipment Checklist

After unpacking this switch, check the contents to be sure you have received all the
components. Then, before beginning the installation, be sure you have all other necessary
installation equipment.
