Special Symbols That Might Appear On the Equipment
This symbol indicates that dangerous voltage levels are present within the equip-
ment. These voltages are not insulated and may be of sufficient strength to cause
serious bodily injury when touched. The symbol may also appear on schematics.
The exclamation point, within an equilateral triangle, is intended to alert the user to
the presence of important installation, servicing, and operating instructions in the
documents accompanying the equipment.
Electrostatic discharge (ESD) can damage the M-eMTA unit and circuit card assem-
blies. Wear an antistatic wrist strap attached to a chassis ground to prevent ESD dam-
age.
