l
Cleaning tool box: used for placing the dust-free cotton and the dust-free cap. Place the
dust-free cotton and the dust-free cap separately from other tools.
l
Cleaning reagent (absolute ethyl alcohol) : used for cleaning the connector of the optical
fiber. It is inflammable, and must be securely saved and kept clean.
l
Optical fiber section magnifier: a microscope (400*) used for checking whether the ends
of the optical fiber connector is clean and without damage.
Impact on the System
Power off the optical transceiver, and then clean the connector of the optical fiber. In this case,
servers carried on the optical port will be interrupted.
Precautions
DANGER
l
Do not look directly into the optical fiber connector or the laser transmit port on the optical
port board without eye protection. Exposure of the combustible to the laser light must be
avoided.
l
Do not clean any optical module before powering off the optical transceiver.
l
To clean the optical transceiver that can be removed and inserted, wear an ESD wrist strap
or wear ESD gloves.
l
Put the dust-free cap into the cleaning tool box immediately after taking it off. Place the
dust-free cap not used in the cleaning tool box, or in the ESD bag for sealed save. Clean it
quarterly (it is recommended to clean it with the ultrasonic cleaner).
l
Keep your hands clean and dry before tailoring the dust-free cotton, and place the dust-free
cotton not used in the clean ESD bag or the cleaning tool box for sealed save.
l
After the cleaning, cover the optical fiber connector, optical transceiver, and adapter that
will not be immediately used with the dust-free caps.
Procedure
Step 1
Clean the ends of the optical fiber connector.
1.
Clip a piece of dust-free cotton into 32 clips with the same size.
2.
Use two clips of dry dust-free cotton (double-layer) to clean the ends of the optical fiber
connector along one direction for one time. For the dirty connector, use the clips of dust-
free cotton (two-layer) dipped with little cleanser to clean the ends of the optical fiber
connector along one direction for one time. Use another dry dust-free cotton clip to clean
the ends of the optical fiber connector along one direction once. Make sure that the ends
of the optical fiber connector is dry.
NOTE
Don not cyclically use the dust-free cotton. Use the dust-free cotton not touched by your hands.
3.
After the cleaning, cover the optical fibers that will not be immediately used with the dust-
free caps.
Step 2
Clean the optical port of the optical transceiver.
