Appendix H Electrostatic Discharge; Overview; Grounding Methods - HP ProLiant BL p-Class GbE2 User Manual

Overview

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.

Grounding Methods

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 grounded cord. 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. 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 an HP
authorized reseller install the part.
NOTE: For more information on static electricity or assistance with product installation, contact your HP
authorized reseller.
