Expansion bus specifications

The PowerEdge R630 system supports PCI express (PCIe) generation 3 expansion cards, which must be installed on the system board by using expansion card risers. This system supports three types of expansion card risers. The following table provides detailed information about the expansion card riser specifications:

Table 1. Expansion card riser specificationsThe expansion card riser 1 has two PCIe slots. The dimensions of slot 1 are: Height=Low Profile, Length= Half length, Link Width=x16. The expansion card riser 2 has one PCIe slot. The dimensions of slot 1 are: Height=Low Profile, Length=Half length, Link Width=x8. The expansion card riser 3 has three PCIe slots. The dimensions of slot 1 are: Height=Low Profile, Length=Half length, Link Width=x16. The dimensions of slot 2 are: Height=Full height, Length=Three-fourth length, Link Width=x16. The dimensions of slot 3 are: Height=Low Profile, Length=Half length, Link Width=x16.
Expansion card riser	PCIe slots on the riser	Height	Length	Link
Riser 1	Slot 1	Low Profile	Half Length	x16
Riser 1	Slot 2	Low Profile	Half Length	x8
Riser 2	Slot 1	Low Profile	Half Length	x8
Riser 2	Slot 1	Low Profile	Half Length	x16
Riser 3	Slot 2	Full height	Three-fourth Length	x16
Riser 3	Slot 3	Low Profile	Half Length	x16

NOTE When using slot 1 on the riser, ensure that both the processors are installed on the system.

NOTE Only a three-fourth length card is supported for the PCIe expansion card slot (slot 2) on riser 3 when no mini-PERC card is installed. Supported length with mini-PERC card installed is half length.
