3.6 RTM Interface
The use of an RTM is optional. I/O signals from the Base Board are routed to Zone 3 where a
connector mates with the RTM. The RTM connection is compliant to the PICMG 3.0 standard.
For the connection between the Hub Board and the RTM two daughter card connectors with
40 differential pairs are used.
Each AMC Bay has eight (B1) or four (B2) pairs of generic interconnects to the RTM Zone 3
(AMC_B1_P13 to AMC_B1_P20 and AMC_B2_P17 to AMC_B2_P20). One SATA/FC inter-
face for mass storage from each AMC Slot is implemented (STOR0 and STOR1). Also an I2C
IPMI connection is implemeted for an intelligent RTM.
The Zone 3 connector has the following pin assignment:
