Important
Observe all warnings in the text or on equipment labels regarding high-voltage or high-
temperature conditions. The following warnings and figures apply to most Fujitsu products.
Plug-In Unit Warnings
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
ATTENTION 1-megohm resistance, that is connected to safety ground.
OBSERVE PRECAUTIONS • Hold only the edges of the plug-in units. Do not touch the
FOR HANDLING integrated circuit (IC) leads or the circuitry.
ELECTROSTATIC
SENSITIVE • Transport and store the plug-in units in the ESD protective
DEVICE bags that the units were shipped in. Always fold the open
end of the bag and secure it with ESD tape.
Anti-electrostatic Markings • 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.
Fiber Warnings
DANGER
Danger: Invisible laser radiation. Avoid direct exposure to the
Invisible laser beam. Never look into the end of a fiber, fiber cord, or fiber pigtail.
radiation from Permanent eye damage or blindness can occur quickly when laser
connectors radiation is present. The label on the left is attached to laser-
when emitting and receiving units as a reminder. Use of controls,
uncoupled adjustments, or procedures other than those specified may result in
AVOID hazardous laser radiation exposure from a fiber-optic pigtail.
DIRECT
Danger: Never handle exposed fiber with your bare hands or touch
EXPOSURE
it to your body. Fiber fragments can enter the skin and are difficult

to detect and remove.
Laser Radiation Label
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.
