Safety - 10
Wear an antistatic wrist strap when carrying or packing a switch.
 Be sure to wear an antistatic wrist strap. If you handle the Switch without wearing an
antistatic wrist strap, the Switch might be damaged by static electricity.
When carrying and packing optional modules, handle them carefully.
 Do not touch a connector when carrying or packing a transceiver or a memory card.
Also, when storing a module, use an antistatic bag.
Use care when handling an air duster.
 Use an air duster specially designed for cleaning optical connectors. Using another
type of air duster could cause the ferrule tip to become dirty.
 Keep the nozzle or container of the air duster from coming into contact with the ferrule
tip. Contact could result in a malfunction.
Use care when handling an optical connector cleaner.
 Always use a dedicated optical connector cleaner. If you use another type of cleaner,
the ferrule tip might become dirty.
 Before cleaning, make sure that the tip of the optical connector cleaner is clean and
free of defects, such as lint, dirt, or other foreign substances. Using a cleaner with a
defective tip might damage the ferrule tip.
 Do not apply excessive pressure when cleaning. Doing so might damage the ferrule
tip.
 Rotate the optical connector cleaner (stick) clockwise only. Rotating the cleaner
alternately clockwise and counterclockwise might damage the ferrule tip.
Maintenance
 Clean any dirty areas on the exterior of the switch with a clean, dry cloth, or a cloth
damp with (but not soaked with) water or a neutral detergent. Do not use volatile
organic solutions (such as benzene or paint thinner), chemicals, chemically treated
cloths, or pesticides because these substances might deform, discolor, or damage
the switch.
If the Switch will not be used for a long time
 For safety reasons, unplug the power cable from the outlet if the Switch will not be
used for a long time.
Disposing of a Switch
 When disposing of a switch, you should either follow local ordinances or regulations
or contact your local waste disposal and treatment facility.
