Troubleshooting the installation

Refer to your workstation’s hardware documentation for detailed information on opening and

closing the system, avoiding electrostatic discharge, and installing and replacing expansion

cards.

Taking Antistatic Precautions  

Static electricity can damage the components inside the workstation base unit, and can damage

cards or texture memory.  To reduce the possibility of electrostatic discharge, do the

following:

u 

Do not remove texture memory or a card from its antistatic bag until you are ready to

install it.

u 

Handle texture memory or a card as little as possible and by the edges only.  Do not drop

texture memory or a card, and do not expose them to extremes of temperature or

moisture.

u 

Use an antistatic foam pad to support a card when installing texture memory.

u 

Use an antistatic wrist strap when handling texture memory or a card.  There is no

increased risk of electrical shock when using the wrist strap.  If the wrist strap does not

snugly contact bare skin, static protection will not be effective.
