PCI/PCI-X Configurations
PCI/PCI-X slots are numbered from 1 through 8 in the server.
Figure 6-26
Slot ID Numbering
The following describes configuration requirements for slots 1 through 8:
•
PCI-X slots 1 and 2 are dedicated for use by the core I/O cards: SCSI HBA card in slot 1 and Gigabit
Ethernet LAN card in slot 2. Slots 1 and 2
are not hot-pluggable
. Additional PCI/PCI-X expansion
cards cannot be placed in slots 1 or 2.
•
Slots 3 and 4 share a PCI-X bus, and slots 5 and 6 share a PCI-X bus. The maximum capability of each of
the shared slots is PCI/PCI-X 66 MHz. If a PCI/PCI-X 133 MHz card is placed in a shared slot, the
PCI/PCI-X 133 MHz card will runs at a maximum of 66 MHz. If different modes (PCI versus PCI-X) or
slower speeds (33 MHz) are used, then the slot automatically downgrades to accept the change.
