The Physical Interface requirements are de-scribed in Fibre Channel-Physical Interfaces - 2 (FC-PI-2). The Framing and Signaling requi
4、rements aredescribed in Fibre Channel-Physical Framing and Signaling - 3 (FC-FS-3). This standard is recommend-ed for new implementations but does not obsolete the existing Fibre Channel standards.Copyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleN

6、nt of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerte
7、d effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchasing, or usingproducts, processes, or procedures not conf
8、orming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person shall have the right or authority to issue aninterpretation of an American National Standard in the na
9、me of the AmericanNational Standards Institute. Requests for interpretations should beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: This American National Standard may be revised orwithdrawn at any time. The procedures of the American Na
