The Intel
®
Server Board S5520UR has one riser slot capable of supporting riser cards for both
1U and 2U system configurations. The riser slot (J4E1) implements Intel
®
Adaptive Slot
Technology. This 280-pin connector is capable of supporting riser cards that meet either the
PCI-X or PCI Express* technology specifications. Some risers can support both full-height and
low-profile add-in cards by using a ‘butterfly’ configuration. The riser card assembly uses
screws to attach the PCI bracket to the riser card assembly.
