spadin Posted May 15, 2012 Share Posted May 15, 2012 Where can I find some documentation on the physical configuration of the PCIe bus for Power PMAC? Is there a hardware manual for the CPU card? Link to comment Share on other sites More sharing options...
hbausley Posted May 18, 2012 Share Posted May 18, 2012 What specifically are you looking for? Dimensional data? It is a PCIe x4 slot specification 1.1 root complex. Link to comment Share on other sites More sharing options...
spadin Posted May 18, 2012 Author Share Posted May 18, 2012 I'm interested in putting a PCIe x4 reflective memory card on the bus, and I'm wondering if the mechanical configuration will accept a standard PCIe card. Link to comment Share on other sites More sharing options...
hbausley Posted May 21, 2012 Share Posted May 21, 2012 From the bottom of the edge connector to the top of the PCIe board, the maximum height that will fit directly in the connector is 3.25 inches. From the front of the PCIe board to the back of the PCIe board the maximum length of a board that will fit is 6.25 inches if there is a backplane UBUS connector behind the PCIe board. However if there is not a connector behind the slot the maximum length would be 6.8 inches. The GE card is 2.7 x 6.6 inches which means it will fit. To install the GE card would require that the Power UMAC CPU card be placed in the first slot of the rack so that there is no UBUS backplane connector to the left of the CPU board. You just want to make sure that you work out the ordering logistics with your distributor so that there is extra room to the left of the first backplane slot. Normally the racks are constructed with the first backplane slot right next to the sheet metal of the rack. Link to comment Share on other sites More sharing options...
