Server Bus/Device/Function Number (B/D/F) Information
The server's B/D/F information may change with PCIe card configurations. You can
obtain the B/D/F information of the server using the following methods:
⚫
BIOS serial port log: If the serial port log has been collected, you can query the
B/D/F information of the server by searching for the keyword
RootBusBDF
.
⚫
UEFI Shell: You can obtain the B/D/F of the server using the
pci
command. Run
the
help pci
command to obtain the specific usage of the
pci
command.
⚫
The following describes how to obtain the B/D/F information on different OSs.
−
Linux OS: You can obtain the B/D/F information of the server running the
lspci -vvv
command.
If the OS does not support the
lspci
command by default, obtain the
pci-utils
package from the
yum
source and install it to make the OS support the command.
−
Windows OS: After installing the
pci-utils
package, run the
lspci
command
to obtain the B/D/F information of the server.
−
VMware OS: The
lspci
command is supported by default. You can directly
obtain the B/D/F information of the server running the
lspci
command.
5.8 PSUs
⚫
The server supports a maximum of four PSUs.
⚫
The server supports AC or DC PSUs.
⚫
The PSUs are hot-swappable.
⚫
The PSUs support 2+2 redundancy or 3+1 redundancy when four PSU are
configured.
⚫
PSUs of the same P/N code must be used in a server.
⚫
The PSUs are protected against short circuit. Double-pole fuse is provided for the
PSUs with dual input live wires.
⚫
If the DC power supply is used, purchase the DC power supply that meets the
requirements of the safety standards or the DC power supply that has passed the
CCC certification.
