The adapter can be installed in any slot other than slot 6 and is not supported in slot 6.
Performance notes
Use the information in this section to help determine the maximum number of adapters that can be
placed in a system while still maintaining optimum performance.
Performance notes regarding GX++ channel adapters
Table 8 on page 17 identifies the slot placement priorities and the maximum number of specified adapters
that can be installed for connectivity. However, for optimum performance, you might want to further
limit the total number of high-bandwidth and extra-high bandwidth adapters. The system supports the
following GX++ adapters feature codes (FCs):
v
FC EJ0G: 2-Port 12X InfiniBand2 adapter
v
FC EJ0H: GX++ LP 1-port PCIe2 x8 adapter
When plugging FC EJ0G GX adapter, ensure that it is placed in GX++ slot 2. If this adapter is installed in
GX++ slot 2, PCIe slot 6 (P1-C7) is not available to install any PCIe adapter. Also, the system power
control network (SPCN) cable of this GX adapter is installed in PCIe slot 1 (P1-C2).
The FC EJ0H GX adapter can be installed in any GX++ slot. The PCIe cable, such as FC EN05 or FC
EN07, connects the FC EJ0H GX adapter and the 58/88 PCIe storage enclosure to the system.
Note: The FC EJ0H GX adapter provides only half of the FC 58/88 PCIe storage enclosure connections
required.
The I/O enclosures, such as FC 5802 and FC 5877, are supported for the 31E/2C system.
I/O expansion units
Find information about the Peripheral Component Interconnect (PCI), PCI-X, and PCI Express (PCIe)
adapters supported in the I/O expansion units that are supported for the systems systems that contain
the POWER7 processor.
