2.3.2 1000BaseKX Ethernet Channels 1 and 2 Connectors (J4 & J5)
The IPN250RTM supports two ultra‐thin pipes on the Control Plane, as defined
by the OpenVPX Payload Slot Profile SLT6‐PAY‐4F1Q2UT2T‐10.2.1. These pipes
are brought out to Molex 0747030017 High Speed Serial Data (HSSDC2)
connectors pinned‐out to the Infiniband Standard. The signal pairs are 100
differential.

2.3.3 PCI Express Interface Connectors (J6, J7)
User‐defined connections include 4 differential pairs of PCIe. These are connected
as two ports of 1‐lane PCIe on the IPN250RTM.
NOTE
The PCIe differential pairs can only be used as two 1-lane ports; they cannot be used together to
form a single 2-lane PCIe port.
J6 and J7 provide the PCIe interfaces via two Molex 75586‐0007 PCI Express
Cabling Standard 8‐lane PCIe cable connectors. On both connectors, only the first
lane is populated; the other lanes have their positive/negative pairs connected
together via 100 terminating resistors, in accordance with the PCIe cabling
standard. J6 provides lane 1 and J7 provides lane 2. All power and management
signals are unused, and have been grounded via 100 resistors to maximize the
noise immunity of the cable.
