Plug-In UnitWarnings
Many plug-in units are stamped with anti-electrostatic markings
(see figures at left) and require special handling and storage.The
following precautions should be strictly observed to avoid damage
from electrostatic discharge (ESD).
• When handling plug-in units for installation, removal, or
option setting, always wear a wrist strap, with a minimum
1-megohm resistance, that is connected to safety ground.
• Hold only the edges of the plug-in units. Do not touch the
integrated circuit (IC) leads or the circuitry.
• Transport and store the plug-in units in the ESD protective
bags that the units were shipped in.Always fold the open
end of the bag and secure it with ESD tape.
• Return the units to Fujitsu in ESD protective bags. Use the
original shipping containers when possible.
All plug-in units should be seated with a slow, firm motion. Many
critical units have longer power connector pins to minimize power
surges during installation.A slow insertion method ensures that
the plug-in units are not damaged.
FiberWarnings
Danger: Invisible laser radiation.Avoid direct exposure to the
beam. Never look into the end of a fiber, fiber cord, or fiber pigtail.
Permanent eye damage or blindness can occur quickly when laser
radiation is present.The label on the left is attached to laser-
emitting and receiving units as a reminder. Use of controls,
adjustments, or procedures other than those specified may result in
hazardous laser radiation exposure from a fiber-optic pigtail.
Danger: Never handle exposed fiber with your bare hands or touch
it to your body. Fiber fragments can enter the skin and are difficult
to detect and remove.
Installation Restriction
Systems shall be installed only in restricted access areas (for
example, dedicated equipment rooms or equipment closets) in
accordance with Articles 110-16, 110-17, and 110-18 of the National
Electrical Code,ANSI/NFPA 70.
