v “Danger notices” on page xiii: These statements indicate situations that can be
potentially lethal or extremely hazardous to you. Safety labels are also attached
directly to products to warn of these situations.

Notes
Notes can provide tips, guidance, suggestions, or advice for simplifying procedures,
clarifying information, or avoiding potential problems. A sample note follows.
Note: The POE LEDs work only when POE is enabled on your device.
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. Wear a wrist grounding strap connected to chassis ground (if the
device is plugged in) or a bench ground. Store all ESD-sensitive components in
antistatic packaging.
Caution notices
A caution notice calls attention to a situation that is potentially hazardous to people
because of some existing condition. A caution notice can be accompanied by
different symbols, as in the examples below:
If the symbol
is...
It means....
A hazardous electrical condition with less severity than electrical danger.
A generally hazardous condition not represented by other safety symbols.
