Care should be exercised when lifting system components. If necessary, get 
assistance to lift a component or install a component in a rack. The weight of 
the system component can be found in the component profiles in “System 
components” on 

.

Before lifting or installing a component:

•

Ensure that the planned location and the route to that location are free of 
obstacles and debris.

•

Determine the weight of the components (see component profiles in 
“System components” on 

).

•

Get help with heavy components or components that are to be placed in 
the upper section of a rack. 

Follow these precautions when handling circuit cards:

Unpack or handle cards away from electric motors, transformers, or 
similar machinery.

Handle cards by the edges only. Do not touch the contacts or 
components.

Set cards on a protective antistatic bag. If an antistatic bag is not 
available, hold the card or set it in a card slot unseated.

Store cards in protective packing. 

Do not stack cards on top of each other unless they are packaged.

Wear a properly connected antistatic wrist strap when you work on the 
equipment. 

Static electricity can damage circuit cards. Wear an 
antistatic wrist strap when handling circuit cards or their 
components.
