PCI-X Slot Locations and Configurations
PCI-X slots are numbered from 1 through 8 in your HP Server. See Figure 4-15, “Slot ID Numbering.”
The following describes configuration requirements for slots 1 through 8:
• PCI 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-plug capable. Additional PCI-X expansion cards may not be placed in slots 1 or 2.
• Slot 3 and 4 is the first pair of shared slots, and slot 5 and 6 is the second pair of shared slots. The maximum capability of
each of the shared slots is PCI-X 66MHz. If a PCI-X 133 MHz card is placed in a shared slot, then the maximum
capability the PCI-X 133 MHz card will run at is PCI-X 66MHz. If different modes (PCI vs. PCI-X) or slower speeds (33
MHz) are used, then the slot to be used will automatically downgrade to accept the change.
Shared slots have card compatibility restrictions. If one of the shared slots is occupied then the card being added to the
second slot is limited by the configuration of the occupied slot. If the new card has a slower capability than the current bus
configuration, it will be rejected. If the new card has a faster capability than the current bus configuration, it will only run
at the bus mode and frequency of the current bus configuration (slower).
1. If you have a 66 MHz card in slot 3, and you hot-plug insert a 33 Mhz card into slot 4, then the operation will not
succeed. The new 33 MHz card will not initialize and the slot will power down because you cannot change bus speed
during hot-plug operations.
