To prevent damage to the system, be aware of the precautions you need to follow when 

setting up the system or handling parts. A discharge of static electricity from a finger or other 

conductor may damage system boards or other static-sensitive devices. This type of damage 

may reduce the life expectancy of the device. 

To prevent electrostatic damage, observe the following precautions: 

•

 

Avoid hand contact by transporting and storing products in static-safe containers. 

•

 

Keep electrostatic-sensitive parts in their containers until they arrive at static-free 
workstations. 

•

 

Place containers on a grounded surface before removing the contents. 

•

 

Avoid touching pins, leads, or circuitry. 

•

 

Always be properly grounded when touching a static-sensitive component or assembly. 

There are several methods for grounding. Use one or more of the following methods when 

handling or installing electrostatic-sensitive parts: 

•

 

Use a wrist strap connected by a ground cord to a grounded workstation or computer 
chassis. Wrist straps are flexible straps with a minimum of 1 megohm 

±

10 percent 

resistance in the ground cords. To provide proper ground, wear the strap snug against the 
skin. 

•

 

Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on 
both feet when standing on conductive floors or dissipating floor mats. 

•

 

Use conductive field service tools. 

•

 

Use a portable field service kit with a folding static-dissipating work mat. 

If you do not have any of the suggested equipment for proper grounding, have a HP 

authorized reseller install the part. 

 

NOTE:  For more information on static electricity or assistance with product installation, contact your HP 
authorized reseller.
