Electrical Safety Guidelines and Precautions
WARNING: Review all guidelines and recommendations in this section
before connecting power to the system.
Before cabling the system power, you must review, understand, and follow
these guidelines and precautions:
■ Before you connect the power sources to the system, be sure that the
circuit to which you are connecting the system is off so that all power is
removed from the circuit and the wires that you are connecting.
■ Take care not to overload the power supply circuit to which you are
connecting the system.
■ Before proceeding with connecting the power lines to the system,
remove all jewelry such as rings, watches, and necklaces.
■ Do not work alone whenever potentially hazardous conditions exist.
■ Before beginning the power cabling procedure, locate the emergency
power-off switch for the location in which you are working.
■ Before proceeding with connecting the power lines to the system, check
your work area for possible hazards such as ungrounded power extension
cables and moist floors.
Avoiding Electrostatic Discharge Damage
Electrostatic Discharge (ESD) can damage module components, causing
complete or intermittent failures in operation. ESD can occur when a module
is improperly handled. To prevent ESD damage to a system module, follow
these guidelines:
■ Always wear an ESD grounding device, such as an ESD wrist strap, when
handing the chassis component. Connection points are available on the
front and rear of the chassis.
■ Store the module in its antistatic bag until you are ready to install it.
■ Handle the module by its edges to avoid touching any pins, leads, or
solder connections on the circuit board.
