2.11 Fan Modules

The fan speed can be adjusted. In normal cases, the fans run at the minimum speed. If the
server temperature increases, the speed will increase accordingly.

l B/D/F stands for Bus/Device/Function Number.
l Root Port (B/D/F) indicates the B/D/F of a CPU internal PCIe root port. Device (B/D/F) indicates
the B/D/F (displayed on the OS) of an onboard or external PCIe port.
l The PCIe slots that support full-height full-length PCIe cards are backwards compatible with full-
height half-length or half-height half-length PCIe cards.
l The PCIe slots that support PCIe x16 cards are backwards compatible with PCIe x8, PCIe x4, and
PCIe x1 cards.
l This table lists the default values of B/D/F. If the CPU sockets are not fully populated or a PCIe
card with a PCI bridge is configured, the values of B/D/F may differ.
l The BIOS of the V5 platform uses the UEFI mode by default. If the legacy mode is used, ensure that
the sum of option ROMs of all PCIe devices does not exceed the upper limit (128 KB) specified by
Intel. Otherwise, some PCIe devices may become unavailable.
A two-slot PRM in I/O module 1 or 2 can house a maximum of one single-slot or dual-
slot PCIe x16 GPU in slot 1 or 4.
A one-slot PRM in I/O module 3 can house a maximum of one single-slot half-height
half-length PCIe x16 GPU.
A three-slot PRM in I/O module 1 or 2 does not support GPUs.
A two-slot PRM in I/O module 3 does not support GPUs.
The server supports a maximum of two dual-slot GPUs or three single-slot GPUs. All
GPUs except half-height half-length P4 GPUs must be installed in dedicated riser cards.
