2.5.1 Installing a PCIe expansion card
The onboard PCI Express slot on the motherboard comes pre-installed with a riser card that
supports two x16 slots (1 x Gen5 x16 link, 1 x Gen5 x8/x16 link) for full-height/half-length
PCIe cards.
2.5 Expansion slots
Make sure to unplug the power cord before adding or removing expansion cards. Failure to
do so may cause you physical injury and damage motherboard components.
To install PCIe expansion cards to the riser card:
1. Remove the screw, then firmly hold the riser card and pull upwards to detach it from
the PCIe slot on the motherboard.
2. Remove the screw from the PCIe lock on the riser card, then remove the PCIe lock
from the riser card.

If a 10GbE PCIe network adapter is installed, it is recommended to connect external power
directly to the power supply units on the front panel, and not via the power socket on the
rear panel.
