PCIe Slot Characteristics
PCIe Slot Characteristics
There are three external PCIe slots and one internal PCIe slot available in the Oracle Server
X7-2. The external slots support optional, standard PCIe cards and are numbered 1, 2, and 3
from left to right when you view the server from the rear. The internal slot, which installs on the
riser in PCIe slots 3 and 4, supports a required internal SAS controller HBA card. For a view
of the back panel that shows PCIe slot numbering, see “Back Panel Components and Cable
Connections” on page 18 .
Note -
PCIe slot 1 is nonfunctional in single-processor systems.
Note -
All of the PCIe slots comply with the PCI Express 3.0 specification and can
accommodate 25 Watt PCIe cards.
The following table lists the characteristics and requirements of the PCIe slots.
