3、 Approved December 13,2000 Secretariat: Information Technology Industry Council (ITI) ) Page 1 of 1 pages Amendments to ANSI NCITS 305-1 998 On page 32, In Table 18 “Format of OVERALL DESCRIPTOR and ELEMENT DESCRIPTOR,” swap the “LSB” and “MSB” labels in bytes 2 and 3 (DESCRIPTOR LENGTH). On page 68

4、, In Table A.2 “Configuration page, using sub-enclosure identifiers,” for the sub-enclosure descriptor labeled “First sub-enclosure descriptor,” change the “Bytes” column entry for PRODUCT REVISION LABEL from “(8 bytes)” to “(4 bytes)” and change the entry for VENDOR SPECIFIC ENCLOSURE INFORMATION f

5、rom “(p - 40 bytes)” to “(p - 36 bytes).” For the sub-enclosure descriptor labeled “Last sub-enclosure descriptor,” change the “Bytes” column entry for PRODUCT REVISION LABEL from “(8 bytes)” to “(4 bytes)” and change the entry for VEN- DOR SPECIFIC ENCLOURE INFORMATION from “(p - 40 bytes)” to “(p

6、- 36 bytes).” An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. The exist- ence of an American National Standard does no

A SCSI command set is defined for managing various non-SCSI elements contained within the enclosure. Copyright American National Stan

15、dards Institute Provided by IHS under license with ANSINot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Ame rica n National Standard Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteri

16、a for approval have been met by the standards developer. Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not

17、necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the st

18、andards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover

19、, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CA

20、UTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current i

21、nformation on all standards by calling or writing the American National Standards Institute. CAUTION: The developers of this standard have requested that holders of patents that may be required for the implementation of the standard disclose such patents to the publisher. However, neither the develo

22、pers nor the publisher have undertaken a patent search in order to identify which, if any, patents may apply to this standard. As of the date of publication of this standard and following calls for the identification of patents that may be required for the implementation of the standard, no such cla

23、ims have been made. No further patent search is conducted by the de- veloper or publisher in respect to any standard it processes. No representation is made or implied that licenses are not required to avoid infringement in the use of this standard. Published by American National Standards Institute
