B: Safety Information and Regulatory Specifications
Shielded Cables
This SGI system is FCC-compliant under test conditions that include the use of shielded cables
between the system and its peripherals. Your system 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 system. If
your monitor cable becomes damaged, obtain a replacement cable from SGI.
Electrostatic Discharge
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 any plastics, in place while you
are operating the system. The shielded cables that came with the unit 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.
