• Leave all components in their ESD-safe packaging until installation, and use only a static-
shielding bag for all storage, transport, and handling.
• Clear the area of synthetic materials such as polyester, plastic, vinyl, or styrofoam
because these materials carry static electricity that damages the equipment.
Care of fiber optic equipment
You must keep fiber optic equipment connections clean and damage-free. Use the information
in this section to properly maintain and care for fiber optic equipment.

Fiber optic cable care
Although the glass fiber in fiber optic cable is protected with reinforcing material and plastic
insulation, it is subject to damage. Use the following precautions to avoid damaging the glass
fiber.
• Do not kink, knot, or vigorously flex the cable.
• Do not bend the cable to less than a 40 mm radius.
• Do not stand on fiber optic cable; keep the cable off the floor.
• Do not pull fiber optic cable harder than you do a cable containing copper wire of
comparable size.
• Do not allow a static load of more than a few pounds on a section of the cable.
• Place protective caps on fiber optic connectors that are not in use.
• Store unused fiber optic patch cables in a cabinet, on a cable rack, or flat on a shelf.
Frequent overstressing of fiber optic cable causes progressive degeneration that leads to
failure.
If you suspect damage to a fiber optic cable, either due to mishandling or an abnormally high
error rate observed in one direction, reverse the cable pairs. If the high error rate appears in
the other direction, replace the cable.
