CAUTION: Before removing or installing components of a device, connect an
electrostatic discharge (ESD) grounding strap to an ESD point and wrap and fasten the
other end of the strap around your bare wrist. Failure to use an ESD grounding strap
could result in damage to the device.
•
Install the device in compliance with the following local, national, and international electrical codes:
•
United States—National Fire Protection Association (NFPA 70), United States National Electrical Code.
•
Other countries—International Electromechanical Commission (IEC) 60364, Part 1 through Part 7.
•
Evaluated to the TN power system.
•
Canada—Canadian Electrical Code, Part 1, CSA C22.1.
•
Locate the emergency power-off switch for the room in which you are working so that if an electrical
accident occurs, you can quickly turn off the power.
•
Make sure that grounding surfaces are cleaned and brought to a bright finish before grounding connections
are made.
•
Do not work alone if potentially hazardous conditions exist anywhere in your workspace.
•
Never assume that power is disconnected from a circuit. Always check the circuit before starting to
work.
•
Carefully look for possible hazards in your work area, such as moist floors, ungrounded power extension
cords, and missing safety grounds.
•
Operate the device within marked electrical ratings and product usage instructions.
•
To ensure that the device and peripheral equipment function safely and correctly, use the cables and
connectors specified for the attached peripheral equipment, and make certain they are in good condition.
You can remove and replace many device components without powering off or disconnecting power to
the device, as detailed elsewhere in the hardware documentation for this device. Never install equipment
that appears to be damaged.
Prevention of Electrostatic Discharge Damage
Device components that are shipped in antistatic bags are sensitive to damage from static electricity. Some
components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging
static voltages whenever you handle plastic or foam packing material or if you move components across
plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge
(ESD) damage, which can cause intermittent or complete component failures:
