Fiber-optic Cable Handling
Observe these precautions when you handle fiber-optic cables:
• Do not coil the cable to less than 96 mm (3.75 in.) in diameter.
• Do not bend the cable to less than 12 mm (0.5 in.) in radius. It is most important that
a cable’s bend radius be no less than 20 times the diameter of the cable.
• Do not pull on the cables; carefully place them into position.
• Do not grasp the cables with pliers, grippers, or side cutters; do not attach pulling
devices to the cables or connectors.
• Keep cables away from sharp edges or sharp protrusions that could cut or wear
through the cable; make sure that cutouts in the equipment have protective edging.
• Protect the cable from extreme temperature conditions.
• Install the connector’s protective cover whenever the connector is not connected.
■ Electrostatic Discharge (ESD) Damage Prevention
Anyone who handles ESD-sensitive components must be aware of the damage that ESD
can cause to electronic components and must take the proper precautions to prevent it.
Also, anyone who performs maintenance on Sun StorageTek equipment must complete
an ESD-basics course.
CAUTION:
Potential damage to equipment: Handle ESD-sensitive components only
under ESD-protected conditions. To meet this requirement, always use
the Field Service Grounding Kit (PN 4711) and always follow these ESD
precautions and procedures when you are servicing Sun StorageTek
equipment or handling ESD-sensitive components.
ESD Precautions
Always take the following general precautions when you work with ESD-sensitive
components:
• Wear ESD protection whenever you install, remove, maintain, or repair Sun
StorageTek equipment.
• Keep ESD-sensitive printed-circuit components in their ESD-protective packages
until you have taken all ESD-preventive steps and you are ready to install the
component.
• Do not allow anyone to touch or handle an unprotected ESD-sensitive component
unless that person has taken all ESD precautions.
