Electrostatic Discharge

Silicon Graphics designs and tests its products to be immune to effects of electrostatic
discharge (ESD). ESD is a source of electromagnetic interference and can cause problems
ranging from data errors and lockups to permanent component damage.
It is important that while you are operating your IRIS Indigo workstation you keep all
the covers and doors, including the plastics, in place. The shielded cables that came with
the system and its peripherals should be installed correctly, with all thumbscrews
fastened securely.
An ESD wrist strap is included with some products, such as memory and graphics
upgrades. The wrist strap is used when installing these upgrades to prevent the flow of
static electricity, and it should protect your system from ESD damage.
