Standards, compliance and reference documents

The drive has been developed as a system peripheral to the highest standards of design and construction. The

drive depends on its host equipment to provide adequate power and environment for optimum performance

and compliance with applicable industry and governmental regulations. Special attention must be given in the

areas of safety, power distribution, shielding, audible noise control, and temperature regulation. In particular,

the drive must be securely mounted to guarantee the specified performance characteristics. Mounting by bot-

tom holes must meet the requirements of Section 11.3.

3.1

Standards

The Cheetah 15K.7 SAS family complies with Seagate standards as noted in the appropriate sections of this

manual and the Seagate

SAS Interface Manual

, part number 100293071.

The drives are recognized in accordance with UL 60950-1 and CSA 60950-1 as tested by UL and EN60950-1

as tested by TUV.

The security features of Cheetah 15K.7 SAS SED models are based on the “TCG Storage Architecture Core

Specification” and the “TCG Storage Workgroup Security Subsystem Class: Enterprise_A” specification with

additional vendor-unique features as noted in this product manual.

3.1.1

Electromagnetic compatibility

The drive, as delivered, is designed for system integration and installation into a suitable enclosure prior to

use. The drive is supplied as a subassembly and is not subject to Subpart B of Part 15 of the FCC Rules and

Regulations nor the Radio Interference Regulations of the Canadian Department of Communications.

The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides

reasonable shielding. The drive is capable of meeting the Class B limits of the FCC Rules and Regulations of

the Canadian Department of Communications when properly packaged; however, it is the user’s responsibility

to assure that the drive meets the appropriate EMI requirements in their system. Shielded I/O cables may be

required if the enclosure does not provide adequate shielding. If the I/O cables are external to the enclosure,

shielded cables should be used, with the shields grounded to the enclosure and to the host controller.

3.1.1.1

Electromagnetic susceptibility

As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is

the responsibility of those integrating the drive within their systems to perform those tests required and design

their system to ensure that equipment operating in the same system as the drive or external to the system

does not adversely affect the performance of the drive. See Tables 13, 14 and 15, for DC power requirements.
