Using Optical Fiber - Symantec NetBackup 5020 Routine Maintenance

1 Safety Precautions
Human Body Injury
The laser sent by the optical interface board is an invisible infrared ray. While maintaining the
device, protect your eyes from the laser; otherwise, the laser may cause permanent injury to
your eyes.

1.4 Using Optical Fiber

You should use optical fibers properly to ensure the normal running of the device; otherwise,
bodily injury or device damage may be caused.
The laser beam of the optical interface board or inside the optical fiber may injure your eyes!
When you install and maintain the optical interface board and the optical fiber, keep your eyes
away from, and never stare into the optical interface or the optical fiber connector.
Cleaning Optical Fiber Connectors and Optical Interfaces
The optical fiber connectors and the optical interfaces of the laser must be cleaned with
special cleaning tools and materials listed as follows:

If the optical interface on the device or on the patch cord is not in use, cover the optical
interface with a dust-proof cap.
When you need to remove the patch cord connected to the optical interface in use, cover
the optical interface and the patch cord connector with dust-proof caps.
When you perform the loopback test on the optical interface with the patch cord, you
must use an attenuator to protect the optical transceiver from the received optical power.
When you use the optical time domain reflectometer (OTDR), disconnect the patch cord
between the peer device and the local device to protect the optical transceiver from the
optical power.
Do not remove or insert the optical transceiver that connects to fiber during operation.
Special cleaning solvent. Isoamylol is preferred, propyl alcohol is the acceptable, alcohol
is not recommended and formalin is forbidden
Non-woven lens tissue.
Special compressed gas
Cotton swabs (medical cotton swab or other long-staple cotton)
