Slot Id Numbering - HP rp4410 Service Manual

Figure 3-32 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-pluggable. Additional PCI/PCI-X
expansion cards must not be placed in slots 1 or 2.
• Slots 3 and 4 share a PCI bus, and slots 5 and 6 share a PCI 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 runs at a maximum of 66 MHz. If different modes
(PCI versus PCI-X) or slower speeds (33 MHz) are used, the slot automatically downgrades
to accept the change.
Shared slots have card compatibility restrictions. If one of the shared slots is occupied, 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 cannot work. If
the new card has a faster capability than the current bus configuration, it only runs at the
bus mode and frequency of the current bus configuration.
• Slots 7 and 8 are single slots. The maximum capability of each slot is PCI/PCI-X 133 MHz.
Only slots 7 and 8 allow 133 MHz, PCI/PCI-X cards to run at full speed. These two slots are
not limited by bus-mode, frequency-related incompatibilities.
Table 3-11 lists the PCI/PCI-X cards slot frequency and bus mode compatibility for shared slots.
