Note 1: All slots support PCIe cards of 75 W or higher power, depending on the
PCIe card model. A GPU is preinstalled with two additional power cables for
sucient power.
Note 2: Table 2-28 lists the default values of B/D/F. If PCIes are not in full
conguration or a PCIe card with a PCI bridge is congured, the values of B/D/F
may
dier.
Note 3: Front I/O modules of other models have the same RAID controller card
slots as the FM-A.
Restricted PCIe slots
Some PCIe cards require I/O resources. When installing PCIe cards in PCIe slots,
note the following points:
● A PCIe card that requires no I/O resources can be installed in any PCIe slot.
● A PCIe card that requires I/O resources cannot be installed in a restricted PCIe
slot that provides no I/O resources because the system has
insucient I/O
resources. Restricted PCIe slots support only PCIe cards that do not require I/O
resources. Table 2-29 describes the restricted PCIe slots of the FM-A.
