72 IBM Power 770 and 780 Technical Overview and Introduction
If you are installing a new feature, ensure that you have the software required to support the
new feature, and determine whether there are any existing PTF prerequisites to install. See
the IBM Prerequisite website for information:

2.8.4 PCIe adapter form factors
IBM 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 servers slots:
– Power 720 and Power 740 (Within the base system, five PCIe half-length slots
are supported.)
–Power750
–Power755
–Power770
–Power780
–Power795
– PCIe slots of the #5802 and #5877 drawers
Low-profile PCIe adapter cards are only supported in low-profile PCIe slots, and full-height
and full-high cards are only supported in full-high slots.
Figure 2-20 lists the PCIe adapter form factors.
Figure 2-20 PCIe adapter form factors
Many of the full-height card features are available in low-profile format. For example, the
#5273 8 Gb dual port Fibre Channel adapter is the low-profile adapter equivalent of the
#5735 adapter full-height. They have equivalent functional characteristics.
