electrical equipment Guidelines
y
Always unplug the power cable before installing or removing a chassis.
y
Locate the emergency power-off switch for the room in which you are working. If an electrical
accident occurs, turn off the power immediately.
y
Do not work alone if potentially hazardous conditions exist.
y
Never assume that power is disconnected from a circuit. Always check. If an electrical accident
occurs, proceed as follows:
o
Use caution. Do not become a victim yourself.
o
Turn off power to the system.
o
If possible, send another person to get medical aid. Otherwise, assess the condition of
the victim and then call for help.

Determine whether the person needs rescue breathing or external cardiac compressions,
then take appropriate action.
Chassis lifting Guidelines
A fully configured CX380X weighs approximately 11 pounds (5 Kilograms). The chassis is not intended to be
moved frequently. Before you install the CX380X, plan chassis placement and ensure that your site is properly
prepared so you can avoid having to move the chassis later to accommodate power sources and network con
-
nections.
Whenever you lift the chassis, follow these guidelines:
y
Always disconnect all external cables before lifting or moving the chassis.
y
Ensure that your footing is solid, and balance the weight of the object between your feet.
y
Lift the chassis slowly; never move suddenly or twist your body as you lift.
y
Keep your back straight and lift with your legs, not your back. If you must bend down to lift the
chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.
y
Lift the chassis from the bottom; grasp the underside of the chassis exterior with both hands.
