Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•
Before beginning any procedure requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
•
Disconnect all power and external cables before moving a chassis.
•
Do not work alone when potentially hazardous conditions exist.
•
Never assume that power has been disconnected from a circuit; always check.
