This chapter provides regulatory information about your workstation.
This chapter contains information on the following topics:
 | Note: Your workstation has several governmental and third-party approvals, licenses, and permits. Do not modify this product in any way that is not expressly approved by Silicon Graphics. If you do, you may lose these approvals and your governmental agency authority to operate this device. |
The Indigo2 IMPACT graphics boards conform to several national and international specifications and European Directives listed on the “Manufacturer's Declaration of Conformity.” The CE mark insignia displayed on each device is an indication of conformity to the aforementioned European requirements.
A “Manufacturer's Declaration of Conformity” is available on the World Wide Web. Look on the system (regulatory) label on the rear of your workstation to determine your CMN (model) number, which you will need to identify your Declaration of Conformity. See Figure B-1 (Exterior of Workstation) at the end of this chapter for the location of your system label.

If you received a regulatory label with a graphics board upgrade, place the label below the logos and over the lower portion of the regulatory label on the rear of your workstation. See Figure B-1 for placement of the upgrade regulatory label.
This device complies with the Class A limits of Part 15 of the FCC Rules. Operation is subject to the following two conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause undesired operation.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.
Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.
This device complies with Class A electromagnetic emissions limits of C.I.S.P.R. Publication 22, Limits and Methods of Measurement of Radio Interference Characteristics of Information Technology Equipment, Germany's BZT Class A limits for Information Technology Equipment, and with Japan's VCCI Class 1 limits.
The equipment described in this guide generates and uses radio frequency energy. If it is not installed and used in accordance with the instructions in this guide, it can cause radio and television interference.
This equipment has been tested and complies with the limits for a Class A computing device in accordance with the specifications in Part 15 of FCC rules. These specifications are designed to provide reasonable protection against such interference in an industrial or office installation. However, there is no guarantee that the interference will not occur in a particular installation. This system is not certified for home use.
You can determine whether your system is causing interference by turning it off. If the interference stops, it was probably caused by the workstation or one of the peripherals. To tell if the interference is caused by one of the peripherals, try disconnecting one peripheral at a time to see if the interference stops. If it does, that peripheral is the cause of the interference.
If your workstation does cause interference to radio or television reception, try to correct the interference by using one or more of the following suggestions:
Turn the television or radio antenna until the interference stops.
Move the workstation to one side or the other of the radio or television.
Move the workstation farther away from the radio or television.
Plug the workstation into an outlet that is on a different circuit from the radio or television. (That is, make certain the workstation and the radio or television are on circuits controlled by different circuit breakers or fuses.)
The Indigo2 IMPACT workstation is FCC-compliant under test conditions that include the use of shielded cables between Indigo2 IMPACT workstation and its peripherals. Your Indigo2 IMPACT workstation and any peripherals you purchase from Silicon Graphics 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 Silicon Graphics, make sure they are shielded. Telephone cables do not need to be shielded.
In Germany, a shielded cable must be used on the Ethernet 10-BASE T port.
The monitor cable supplied with your system uses 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, a replacement cable should be obtained from Silicon Graphics.
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 Indigo2 you keep all the covers and doors, including the plastics, in place. The shielded cables that came with the workstation 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.
