3、ace pages iii and iv with the associated pages of this supplement. The changes reflect the material in new annexes B and C. On page 2, add a new definition: 3.1.3 Admin micropacket: A HIPPI-6400 micropacket used for configuration and management. It consists of a single micropacket with TYPE = “Admin

On page 2, add a new definition: 3.1.6 electromagnetic compatibility (EMC): The ability of a device, equipment, or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagneti
5、c disturbances to anything in that environment. 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 developers nor the publisher have undertaken a pate
6、nt search in order to identify which, if any, patents may apply to this standard. As of the date of publication of this standard, following calls for the identification of patents that may be required for the implementation of the standard, notice of one or more such claims has been received. By pub
7、lication of this standard, no position is taken with respect to the validity of this claim or of any rights in connection therewith. The known patent holder(s) has (have), however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and co
8、nditions to applicants desiring to obtain such a license. Details may be obtained from the publisher. No further patent search is conducted by the developer or publisher in respect to any standard it processes. No representation is made or implied that this is the only license that may be required t
9、o avoid infringement in the use of this standard. 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 existence of an
10、American National Standard does not in any respect preclude anyone, whether he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic review and users
11、 are cautioned to obtain the latest editions. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American Na

14、gton, DC 20005 Page 2 of 15 pages On page 2, On page 3, On page 14, On page 20, On page 24, On page 25, change the definition for Message to: Message: An ordered sequence of one or more micropackets that have the same VC, Originating Source, and Final Destination. Messages are the basic transfer uni
15、t between an Originating Source and a Final Destination. The first micropacket of a Message has TYPE = Header. Subsequent micropackets of the Message have TYPE = Data. The last micropacket, which may also be the first micropacket, has the TAIL bit set. (See 4.4.) add new acronyms: EMC - electromagne
16、tic compatibility, EM1 - electromagnetic interference, RFI - radio-frequency interference add a second note to 6.2, page 14, reading: ”Since only one Message (see 3.1.9) can be on a VC at a time, a large Message can block other Messages from that VC. For maximum performance, implementations should p
17、rovide sufficient capability so that the maximum Message size used on a particular VC can be transmitted and received at the full 6400 Mbits rate.” change EtherType = 8183 from ”Reserved” to ”Carrying Scheduled Transfer Protocol with preceding 4-byte zero fill and ST-length (specified in NCITS 1245-
18、D)2”. replace page 24 with the associated page of this amendment. All of the changes are in Table 3, the signal line bit assignments in a 16-bit system. replace page 25 with the associated page of this amendment. All of the changes are in Table 4, the signal line bit assignments in an 8-bit system.
19、On pages 40-41, replace pages 40 and 41 with the associated pages of this amendment. The changes include changing the name ”Berg Micropax 100” to ”FCI Micropax 100” in two places. Added information about the receptacle for PCI applications. Changed the name ”Berg Electronics” to ”FCI (previously kno
20、wn as Berg Electronics)” in the note. The last 7 paragraphs of 16.5 concerning cable gounding were also changed. On page 43, On page 44, After page 51, replace page 43 with the associated page of this amendment. The changes are in the dimensions for A7 and A8. replace page 44 with the associated pag
21、e of this amendment. The change is to replace the cable connector figure with one showing a cable assembly. add new pages for normative Annex B describing the optional copper cable connector, and for informative Annex C describing interoperability of the different connectors. The editors realize tha
22、t normative Annex B should precede informative Annex A, but in the interest of reduced page count, this amendment does not follow that practice. The order will be corrected in any future revisions of the standard. ANSI NCITS 323:1998/AMI -2001 Page 3 of 15 pages Page 6 Summary of timeouts . . 32 7 8
