Safety Tips
Use these tips as safety guidelines when installing and working around this equipment:
•
Locate the emergency power off switch for the room in which you are working in order to be able to
quickly turn off power, if an electrical accident occurs.
•
Disconnect all power before installing or removing a chassis.
•
Do not work alone if potentially hazardous conditions exist.
•
Never assume that power is disconnected from a circuit. Always check.
•
Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension
cables, 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, and then take
appropriate action.
Preventing Electrostatic Discharge Damage
Always follow ESD-prevention procedures when removing and replacing components. These procedures
include:
•
Ensure that the chassis is electrically connected to earth ground.
•
Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.
•
Connect a clip to the ESD-strap connection jack (to the left of the power switch on the rear of the chassis)
or to an unpainted chassis frame surface.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1
МΩ
and 10
МΩ
.
