AMC.1 - PCI Express and Advanced Switching A subsidiary specification to AMC.0 (Draft 0.9a of AMC.1 Revision 1.0) Sponsor: PICMG AMC.1 Subcommittee of the PICMG special interest group Approved xx/xx/2004 (anticipated) PICMG BoD Do Not Specify or Claim Compliance to this Draft Specification Abstract: AMC.1 specifies Port allocation and usage for implementing PCI Express and Advanced Switching on an AMC.0 compliant Module and On-Carrier device. The intent is that this specification will cre- ate a unified industry approach so as to encourage interoperable and “plug-and-play” implementa- tions. AMC.1 is a subsidiary specification and is therefore dependent upon AMC.0 for definition of all mechanical, management, thermal, power and interconnect requirements.
