PCI-X expansion cage option
The PCI-X expansion cage option converts one PCI Express slot into two PCI-X slots for additional
expansion board capability. The PCI-X expansion cage does not support expansion boards with internal
cabling requirements.
After installing the PCI-X expansion cage, run RBSU and enable the Optional PCI-X Riser Fan Monitoring
setting from the Advanced Options menu. Enabling this option provides health monitoring of the riser fans
which appear as fans 7 and 8. In addition, both expansion boards installed in the PCI-X expansion cage
appear as slot 6.
IMPORTANT: The following conditions apply for the PCI-X expansion cage:
• Only one HP Smart Array controller can be installed in the PCI-X expansion cage at one
time.
• Only one HP Single-channel U320 storage controller can be installed in the PCI-X
expansion cage at one time.
• An HP Smart Array controller and an HP Single-channel U320 storage controller cannot
both be installed in the PCI-X expansion cage at the same time.
