Treat optical fiber cables with care and respect.
Rough treatment of optical fiber cables could cause deterioration of characteristics or
mechanical damage (line disconnection).
・Ensure a minimum bending radius of 38mm.
・Do not drop a cable on the floor or otherwise shock it.
・If not connecting a cable, place caps on it. When connecting a cable, do not discard the
caps but save them (as well as those for connectors on the unit).
As the optical power is attenuated by dust or dirt and it may cause data error, be sure to
clean the optical connector using the following procedure when optical fibre cable is
inserted to the product:
1. Spray air or another parts cleaning gas on the optical connector for several seconds.
2. Wipe the optical connector lightly several times with a non-fibrous cloth wetted with
isopropyl alcohol.
3. Spray parts cleaning gas on the optical connector for several seconds again.
Be careful when handling the laser products.
The product contains class-1 laser products based on JIS C6802, EN60825-1 (+A-11), and
21 CFR 1040.10 and 1040.11 issued by the U.S. Food and Drug Association (FDA).
Do not look straight at the optical fiber cable, optical fiber connector, or laser transceiver
module because there is a risk of eye damage, depending on the laser power level.
Note that JIS C6802, EN60825, and IEC60825 defines class-1 laser as the level of laser
which causes no injury if human is exposed to it.
Prevent damage from electrostatic discharge.
Components in the device is sensitive to static electricity. Even a slight discharge, could
damage the electrical components in the device. Even if a component receives damage, an
error may not occur immediately, but the state is aggravated and is causing a
"intermittent" problem gradually.
Before touching the product, touch an unpainted metal surface. It is effective to use
commercially available anti-static wrist strap with a clip terminal.
・If the frame of the device is metal, touch the frame.
・Otherwise, touch the wall part of the product or a screw of the door frame.
・Stay as still as possible when touching the components inside the product to avoid
produce static electricity.
Do not pinch your finger with rails or other components.
Be careful sufficiently not to pinch or cut your fingers with the rails etc. when you
mount/unmount the product on the rack.
Do not apply any load on the device pulled out from the rack.
Do not apply any load on the device pulled out from the rack. Doing so bends the frame of
the device. Consequently, the device cannot be pushed back into the rack. Placing an
object on the device may also cause personal injury if the device drops.
Relocation of the product.
Consult with your service representative for relocation of the product.
Disposal of the product.
The product contains liquid crystal display (LCD). Consult with your service
representative before disposing of the product. Dispose of the unit according to the
ordinance of the local government.
