2.0Standards, 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 8.3.

2.1Standards

The Cheetah 15K.6 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 Cheetah 15K.6 disk drive is a UL recognized component per UL1950, CSA certified to CAN/CSA C22.2 No. 950-95, and VDE certified to VDE 0805 and EN60950.

The security features of Cheetah 15K.6 SAS FDE 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.

2.1.1Electromagnetic 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.

2.1.1.1Electromagnetic 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 12, 14 and 16, for DC power requirements.
