PCI Card Load Order
PCI slots are numbered 1 through 12, starting from the bottom of the PCI Backplane. PCI slots 1 and 3 are
dedicated for use by the servers Core I/O cards. The Core I/O functions are shared between two cards; an
MP/SCSI card which must be located in slot 1, and a LAN/SCSI card which must be located in slot 3.
If the VGA/USB card is installed, it must reside in PCI slot 2. If the VGA/USB card is not installed, slot 2 may
be used for other supported PCI Cards.
A RAID card is available for use with Microsoft Windows and Linux. If the RAID card is installed, it must
reside in PCI slot 4. If the RAID card is not installed, slot 4 may be used for other supported PCI Cards.
PCI Card Performance Considerations
Slot 2, which shares a 33MHz bus with slot 1, is the lowest performance slot in the system available and is
recommended for use with 33MHz PCI Cards.
A common 66MHz bus is shared between slots 4 and 5, slots 6 and 7, and slots 8 and 9. To maximize PCI bus
bandwidth, populate only one slot on each bus and leave the second slot empty. For example, install cards in
slots 4, 6, and 8, but leave slots 5, 7, and 9 empty.
Slots 10, 11, and 12 are the highest performance slots in the system. Each of these slots provide an individual
bus with 500MB/second peak data rate at 133MHz.
