Electrical Equipment GuidelinesFollow 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.
