3.2.5 ProLiant DL145 G3 Riser Board Assemblies
The DL145 G3 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:
You cannot install the PCI Express x4 and PCI-X riser boards at the same time. You also cannot
install the HTX and PCI Express x16 riser boards at the same time.
Expansion Board Installation Guidelines
Use only HP-supported expansion boards that meet the following specifications:
• HTX: Full-sized, 1 GHz, 16x16
• PCI Express x4: Low-profile
• PCI Express x16: Full-sized
• PCI-X: Low-profile, 64-bit, 3.3 V, 133 MHz
