Riser board assemblies
The server supports up to two expansion boards installed on riser boards. With the appropriate riser boards, the
two riser board assemblies that come with the server convert the expansion slots on the system board to slots that
are positioned at a 90° angle from the system board. You can then install expansion boards in a position
parallel to the system board.
The system comes with one full-sized assembly and one low-profile assembly. The full-sized assembly supports
either an HTX riser board or a PCI Express x16 riser board. The low-profile assembly supports either a PCI
Express x4 riser board or a PCI-X riser board.
NOTE: Some full-size expansion boards may not be supported due to a small blockage caused by the molded
connector on the end of the AC power cable. The connector molding reduces the overall component space
near the end of full-size expansion boards.
