Manufacturer's Regulatory Declarations

The SGI 1400 server products conform to several national and international specifications and European Directives listed on the “Manufacturer's Declaration of Conformity.” The CE insignia displayed on each device is an indication of conformity to the European requirements.

Caution: Each SGI 1400 server system 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.

Server CMN Number

The CMN (model) number, for the SGI 1400 server is A021. This model number is also shown on the system label on the back of the unit.

Series Number

The series number is on the serial number label on the back of the SGI 1400 server.

You need to know the series number and CMN number for downloading the Manufacturer's Declaration of Conformity from the World Wide Web.

Manufacturer's Declaration of Conformity

A “Manufacturer's Declaration of Conformity” is available on the World Wide Web. Look on your system (regulatory) label on the rear of the system to determine your CMN (model) number, and on the serial number label to determine your series number. You need both to identify your Declaration of Conformity. To locate the information on the World Wide Web, enter the following in your Web browser location window:

Upgrade Regulatory Label

If you received a regulatory label with an upgrade, place it on the back of the system near the Manufacturer's Declaration of Conformity label.

Class A Compliance

This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

  • Reorient or relocate the receiving antenna.

  • Increase the separation between the equipment and receiver.

  • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

  • Consult the dealer or an experienced radio/TV technician for help.

Caution: The user is cautioned that changes or modifications to the equipment not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Electromagnetic Emissions

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.

Also, 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.

Korean Class A Regulatory Notice

Shielded Cables

The SGI 1400 server system 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 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.

Optional monitor cables supplied with your server 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, a replacement cable should be obtained from Silicon Graphics.

Electrostatic Discharge

Silicon Graphics 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 while you are operating the server system you keep all the covers and doors, including the plastics, in place. 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 when installing these upgrades to prevent the flow of static electricity, and it should protect your system from ESD damage.
