1.12 Agency certification
1.12.1 Safety certification
The drive is recognized in accordance with UL 1950 and CSA C22.2
(950) and meets all applicable sections of IEC 950 and EN 60950 as
tested by TUV North America.
1.12.2 Electromagnetic Compatibility
Hard drives that display the CE marking comply with European Union
requirements specified in Electromagnetic Compatibility Directives. Test-
ing is performed to standards EN50082-1 and EN55022-B.
Seagate uses an independent laboratory to confirm compliance with the
EC directives specified in the previous paragraph. Drives are tested in
representative end-user systems. Although CE-marked Seagate drives
comply with the directives when used in the test systems, we cannot
guarantee that all systems will comply with the directives. The drive is
designed for operation inside a properly designed enclosure, with prop-
erly shielded I/O cable (if necessary) and terminators on all unused I/O
ports. Computer manufacturers and system integrators should confirm
EMC compliance and provide CE marking for their products.
1.12.3 FCC verification
These drives are intended to be contained solely within a personal
computer or similar enclosure (not attached as an external device). As
such, each drive is considered to be a subassembly even when it is
individually marketed to the customer. As a subassembly, no Federal
Communications Commission verification or certification of the device is
required.
Seagate Technology, Inc. has tested this device in enclosures as de-
scribed above to ensure that the total assembly (enclosure, disc drive,
motherboard, power supply, etc.) does comply with the limits for a Class
B computing device, pursuant to Subpart J, Part 15 of the FCC rules.
Operation with noncertified assemblies is likely to result in interference
to radio and television reception.
