PowerEdge R710 Technical Guide 40
PCI Slots
Overview
The PowerEdge R710 has two PCI Express risers: Riser 1 and Riser 2. Each riser connects to the planar through a
x16 PCI Express connector.
• Riser 1 consists of two x4 slots and a third x4 slot dedicated for internal SAS storage through the PERC
6i or SAS 6/iR.
• The default Riser 2 consists of two x8 PCI Express connectors.
• There is also an optional x16 Riser 2 that supports one x16 PCI Express card.
To ensure proper cooling, no more than two of the four expansion cards can have a power consumption of
greater than 15W (up to 25W maximum each), not including the integrated storage controller.
The system does not support hot-plug or hot-removal of PCI Express cards.
For more information on installing expansion cards and expansion-card priority, see the Expansion Cards and
Expansion-Card Risers section in the Installing System Components chapter of the Dell PowerEdge R710 Systems

PCI Express Risers
The two PCI Express risers provide up to four expansion slots and one slot dedicated for the integrated storage
controller card. The slots meet the following requirements:
• Two x8 and two x4 PCI Express Gen2 slots, each connected to the IOH
• One x4 PCI Express Gen1 slot for internal storage connected to the IOH
• Support for three full-height 9.5”-long PCI Express cards and one full-height bracket, low-
profile PCB PCI Express card
• Support for customer installation of a full-length 12.2" PCI Express card in Slot 1 on Riser 1
• System support for 25 W maximum power for the first two cards and 15 W for the third and
fourth cards (lower power support on third and fourth cards due to system thermal
limitations)
• Optional x16 riser to accommodate interface cards for external GPU boxes that supports a
maximum power of 25W (use of riser reduces the number of PCI Express slots from four to
three)
The following riser restrictions apply for the R710:
• The riser connectors on the planar do not support plugging in a standard PCI Express card.
• Two R710 risers must be installed or the system will not power up.
