10 Safety and equipment care information
•
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
Fiber optic equipment connections must be kept clean and damage-free.
Use the information in this section to properly maintain and care for fiber

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 any harder than you would a cable
containing copper wire of comparable size.
•
Do not allow a static load of more than a few pounds on any 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.
