Electrostatic Discharge

The Origin 3900 server is FCC-compliant under test conditions that include the use of
shielded cables between the server and its peripherals. Your server and any peripherals
you purchase from SGI have shielded cables. Shielded cables reduce the possibility of
interference with radio, television, and other devices. If you use any cables that are not
from SGI, ensure that they are shielded. Telephone cables do not need to be shielded.
Optional monitor cables supplied with your system use additional filtering molded into
the cable jacket to reduce radio frequency interference. Always use the cable supplied
with your server. If your monitor cable becomes damaged, obtain a replacement cable
from SGI.
SGI designs and tests its products to be immune to the 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 you keep all the covers and doors, including the plastics, in place
while you are operating your server. The shielded cables that came with the server and
its peripherals should be installed correctly, with all thumbscrews fastened securely.
An ESD wrist strap may be included with some products, such as memory or PCI
upgrades. The wrist strap is used during the installation of these upgrades to prevent the
flow of static electricity, and it should protect your system from ESD damage.
