Chapter 2 Preparing for Installation
Safety
Follow these guidelines when you work on equipment powered by electricity.
•
Locate the emergency power-OFF switch for the room in which you are working. Then, if an
electrical accident occurs, you can act quickly to turn OFF the power.
•
Before working on the system, unplug the power cord.
•
Disconnect all power before doing the following:
–
Installing or removing a chassis
–
Working near power supplies
Warning
When installing the unit, the ground connection must always be made first and
disconnected last.
•
Do not work alone if potentially hazardous conditions exist.
•
Never assume that power is disconnected from a circuit. Always check.
Warning
Read the installation instructions before you connect the system to its power source.
•
Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
•
If an electrical accident occurs, proceed as follows:
–
Use caution; do not become a victim yourself.
–
Turn OFF power to the system.
–
If possible, send another person to get medical aid. Otherwise, assess the condition of the
victim and then call for help.
–
Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Warning
This product relies on the building's installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. is used
on the phase conductors (all current-carrying conductors).
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage
occurs when electronic components are improperly handled and can result in complete or intermittent
failures.
Always follow ESD-prevention procedures when you remove and replace components. Ensure that the
chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it
makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to
safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and
cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of
the chassis.
