Intel Netstructure MPRTM0020 Rear Transition module manual RTM Connector Zone 3 P31 Pinout

Module Components

4.3.7Zone 3 Rear Transition Module Data/Control Connectors

The MPRTM0020 implementation includes three data connectors (P31, P32, P33) that mate directly to the MPCBL0020 Single Board Computer without connecting through the backplane. Each Zone 3 data/control connection consists of 120-pin HM-Zd connector with 40 differential pairs which allows high-speed signals to be passed between the boards.

4.3.7.1Zone 3 Rear Transition Module Data/Control Connector (P31)

The signals that are routed through P31 are the IEEE 1149.1 JTAG signals, SAS storage ports, USB

2.0signals, and serial and fabric interface Ethernet ports. Table 9 provides the basic pinout of the connector, and Table 10 provides more detail about the signals.

Table 10.		P31 Signal Descriptions (Sheet 1 of 2)
Pin		Signal	Comments
A1	RMD_INT#		This signal is driven by the RMD on non-intelligent RTMs to alert the SBC that there is a
			sensor needing attention. It is required on all SBCs and RTMs.
B1, C1	Reserved		Reserved
			Test Data In signal as defined in JTAG. SBCs must connect this signal into the test data chain
D1	TDI		(i.e., in line with TDO connections from other chips), but must have a means to bypass this
			connection if an RTM is not installed.
E1	Reserved		Reserved
F1	TDO		Test Data Out signal as defined in JTAG. See TDI comments above. Output of RTM
G1	Blue HS LED		Blue Hot Swap LED
H1	Reserved		Reserved
A2-D3	SA[x]TX+, SA[x]TX-,		Storage architecture signals for transmit and receive portions of differential pairs. Three SAS
	SA[x]RX+, SA[x]RX-		ports are routed to the RTM.
E3-H3	No Connect		No Connect
			PHY-level 10/100/1000Base-T signaling routed to the RTM. Row 4 is for the first Ethernet port,
A4-H5	FI_Dxy+, FI_Dxy-		row 5 is for the second Ethernet port. These Ethernet ports are routed from the “Physical
			Level” Fabric Interface of the MPCBL0020 Single Board Computer, and have gone through
			the magnetics on the SBC.
