2、y CouncilApproved May 25, 2004American National Standards Institute, Inc.AbstractThis standard describes the requirements for an interconnecting Fabric consisting of multiple FabricSwitch elements to support the ANSI INCITS Fibre Channel - Framing and Signaling (FC-FS) standard(ANSI INCITS 373-2003)
3、 and the ANSI INCITS Fibre Channel - Physical Interface (FC-PI) standard (ANSI INCITS 352-2002).Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is esta
4、blished when, in the judgement 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 con
5、sidered, and that a concerted 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, proce
6、sses, or procedures not conforming 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
7、 National Standard in the name 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 p
8、rocedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard. Purchasers of American National Standards mayreceive current information on all standards by calling or writing the AmericanNational Standards Institute.Amer

11、isher. However, nei-ther the developers nor the publisher have undertaken a patent search in order to identify which, ifany, patents may apply to this standard. As of the date of publication of this standard, followingcalls for the identification of patents that may be required for the implementatio
12、n of the standard,notice of one or more such claims has been received. By publication of this standard, no positionis taken with respect to the validity of this claim or of any rights in connection therewith. The knownpatent holder(s) has (have), however, filed a statement of willingness to grant a
13、license underthese rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to ob-tain such a license. Details may be obtained from the publisher. No further patent search is con-ducted by the developer or publisher in respect to any standard it processes. No representa
