Page 3: Overview
The PCIe x4 Gen 2 expansion kit is used to extend the PCI Express bus from a host server to an external PCIe I/O board. The host adapter card inserts into a PCIe slot of the server. It then cables to a downstream target adapter card. The target adapter card inserts in the OSS Gen 2, 2-slot backplane. -
Page 4: Features
The Host adapter card inserts into any PCI Express x4, x8, 16 slot on the host motherboard. The Target adapter card operates ONLY in the OSS backplane target slot. Both Host and Target adapter cards have PWR and CBL LED indicators. -

Page 6: Component Identification
The PCIe x4 expansion kit contains two cable adapter boards, the host cable adapter and the target cable adapter. The host adapter inserts into the host computer’s PCIe x4, x8 or x16 slot. The host cable adapter (Part # OSS-PCIe-HIB25-x4-H) allows communication between a processor and an I/O point. -

In the following tables, a 0 indicates that a zero Ohm resistor has been installed and a 1 indicates no resistor. In rare cases, mostly where non- OSS equipment is used with the HIB-25x4, these adjustments may need to be changed. The following tables are made available for this purpose. - Page 12 Ground Ground PERp2 Receiver differential pair, Lane 2 Ground PERn2 PETp3 Transmitter differential pair, Ground Lane 3 PETn3 Ground Ground PERp3 Receiver differential pair, Lane 3 RSVD Reserved PERn3 PRSNT2# Hot-Plug presence detect Ground Ground RSVD Reserved OSS-KIT-EXP-3500-2M | 12...
- Page 13 Although support of CWAKE# is optional from the board side connector perspective, an allocated wire is mandated for the cable assembly. Board side pin-outs on both sides of the Link are identical. The cable assembly incorporates a null modem for the PCIe transmit and receive pairs. OSS-KIT-EXP-3500-2M | 13...
