Pcie Adapter Form Factors - IBM Power 720 Overview

Remember:
The PCIe2 4-port 1 Gb Ethernet adapter (FC 5899) is the only PCIe adapter that is
allowed at the P1-C7 PCIe x4 slot in the Power 720 and Power 740 servers. Other
supported PCIe adapters on the Power 720 and Power 740 are not supported in the
P1-C7 slot.
If a GX++ adapter, such as the FC EJ03 or FC EJ04 is installed at the GX++ slot 2
(P1-C8), the PCIe2 LP 4-port 1 Gb Ethernet adapter (FC 5260) must be installed in any
of the available PCIe x8 Gen2 slots.
IBM i IOP adapters are not supported in the Power 720 and Power 740 systems.

2.7.2 PCIe adapter form factors

IBM POWER7 and POWER7+ processor-based servers are able to support two form factors
of PCIe adapters:
PCIe low-profile (LP) cards, which are used with the Power 710 and Power 730 PCIe slots.
Low-profile adapters are also used in the PCIe riser card slots of the Power 720 and
Power 740 servers.
PCIe full-height and full-high cards, which are plugged into the following server slots:
– Power 720 and Power 740 (Within the base system, five PCIe half-length slots
are supported.)
– Power 750
– Power 755
– Power 760
– Power 770
– Power 780
– Power 795
– PCIe slots of external I/O drawers, such as FC 5802 and FC 5877
Low-profile PCIe adapter cards are supported only in low-profile PCIe slots; full-height cards
are supported only in full-height slots.
