1.3.1  AMC card connections  

The four AMC slots have identical features, and each accommodates a half width, 
mid height module.  The ATCA-S201 accepts AMC cards conforming to either PCI 

express signaling (AMC.1) or Storage signaling options (AMC.3).   AMC feature 

support details: 

  PCI-Express x4 on AMC ports 4-7 
  PCI reference clock on FCLKA 

  3Gb SAS/SATA on AMC port2 

  3Gb SAS/SATA on AMC port3  

  SAS hot swap support 
  Face plate height x width, 18.96 x 73.8mm 

  IPMB-L  

  72W max each slot (120W shared with all AMC slots) 

1.3.2  DDR2 SODIMM 

A 72 bit SODIMM socket is populated with a DDR2 memory module, and operated 
at 533MHz.  The ATCA applies ECC (error correction code) algorithms to this 

memory to ensure data integrity of both the storage and program code stored in it.  

Single bit errors are automatically detected and corrected by these ECC algorithms. 

1.3.3  Zone 1, power backplane connections 

The Zone-1 connector brings 48V DC power into the ATCA main board.   This power 

is regulated and split into several lower voltages by discrete components and a pair 

of power modules that are affixed to the ATCA carrier.  Together, these devices 

convert 48V source and distributes power amongst the ATCA local onboard needs, 
AMC slots and advanced rear transition module (RTM). 

1.3.4  Zone 2, backplane connections 

This connector carries the Ethernet links to the chassis backplane.  All Ethernet ports 

on this connector are full duplex and all ports support access to advertised storage 
resources.   This connector includes the following Gigabit Ethernet ports: 

 

  2 Fabric channels, redundant 10GbE XAUI connections 

  2 Base channels, redundant 1GbE base connections  

1.3.5  Zone 3, Advanced RTM connector 

This connector conforms to the advanced rear transition module (RTM) 3-row 

connector standard.  The following functions are routed to this connector:  

  8x PCI-express 
  4x SAS/SATA target connections 

  4x SAS/SATA initiator connections 

  I
