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. If you are using a DC power supply unit, turn off the circuit breaker at the
supply of power.
Disposal 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.
