needed, to perform required service actions. The customer is also responsible for using professional
movers/riggers in the case of equipment relocation or disposal.
DANGER: Heavy equipment—personal injury or equipment damage might
result if mishandled. (D006)
Safety labels
As an added precaution, safety labels are often installed directly on products or product components to
warn of potential hazards. These can be either danger or caution notices, depending upon the level of the
hazard.
The actual product safety labels may differ from these sample safety labels:
DANGER: Hazardous voltage, current, or energy levels are present inside
any component that has this label attached. Do not open any cover or
barrier that contains this label. (L001)
DANGER: Rack-mounted devices are not to be used as a shelf or work
space. (L002)
DANGER: Multiple power cords. The product might be equipped with
multiple power cords. To remove all hazardous voltages, disconnect all
power cords. (L003)
DANGER: Hazardous voltage present. Voltages present constitute a shock
hazard, which can cause severe injury or death. (L004)
CAUTION: Hazardous moving parts nearby. (L008)
Attention notices
An attention notice indicates the possibility of damage to a program, device, or system, or to data. An
exclamation point symbol may accompany an attention notice, but is not required. A sample attention
notice follows:
Attention: Do not bend a fibre cable to a radius less than 5 cm (2 in.); you can damage the cable.
Tie wraps are not recommended for optical cables because they can be easily overtightened,
causing damage to the cable.
ESD precautions
Attention: Many of the field replaceable units (FRUs) are sensitive to electrostatic discharge (ESD),
and can potentially be damaged by improper handling. When working with any FRU, use correct
ESD precautions:
• Attach ground to the indicated area on the chassis
