Site Preparation
NOTE
Unshielded twisted pair (UTP) cable can build up ESD charges when being pulled into a new
installation. Before installing category 5 UTP cables, discharge ESD from the cable by plugging it into a
port on a switch or any network device that is not powered on.

Fiber Optic Cable
Fiber optic cable must be treated gently during installation. Every cable has a minimum bend radius, for
example, and fibers will be damaged if the cables are bent too sharply. It is also important not to stretch
the cable during installation. We recommend that the bend radius for fiber optic cable equals 2-inch
(5.08 cm) minimum for each 90 degree turn as shown in Figure 12.
