HP Cluster Platform Server and Workstation Overview

1.6.3 PCI-X Slot Assignment and Supported Options
PCI-X slots are numbered from 1 through 8, with the interconnect card in slot 8 on the far right
of the enclosure, as shown in Figure 1-27. The configuration requirements for slots 1 through 8
are as follows:
• PCI slots 1 and 2 are dedicated for use by the core I/O cards—SCSI HBA card in slot 1 and
dual-port gigabit Ethernet LAN card in slot 2. Slots 1 and 2 are not hot-pluggable capable.
Do not install additional PCI-X expansion cards in slots 1 or 2.
• Slots 3 and 4 are the first pair of shared slots, and slots 5 and 6 are the second pair of shared
slots. The maximum capability of each of the shared slots is PCI-X 66 MHz. If a PCI-X 133
MHz card is installed in a shared slot, its maximum capability is PCI-X 66 MHz. If different
modes (PCI instead of PCI-X) or slower speeds (33 MHz) are installed, the slot automatically
downgrades to accept the change.
• Slots 7 and 8 are single slots. The maximum capability of each slot is PCI-X 133 MHz. Only
slots 7 and 8 will allow 133 MHz, PCI-X cards to run at full speed. These two slots are not
limited by bus-mode, frequency-related incompatibilities. Slot 8 is always used for the
interconnect PCI card.
Table 1-14 summarizes the slot assignments and the required and optional PCI cards.

The HP Cluster Platform hardware does not impose any restrictions on supported options.
However, the system software can restrict supported options to guarantee performance, or to
reduce qualification test matrices.
1.6.4 Installing or Removing a PCI Card
The HP Integrity rx4640 provides eight PCI slots across five PCI-X buses and supports
hot-pluggable PCI-X devices. However, you should not install the interconnect PCI adapter while
the server is running. Also, take care to use only slot 8 on bus 5, which is the designated slot for
HP Cluster Platform installations.
Detailed information on installing PCI cards is provided in the HP Integrity rx4640 Maintenance
Guide http://docs.hp.com/en/rx4640_maint/rx4640_maint.pdf.
When installing or removing PCI cards, heed the warnings and cautions listed in the “Important
Safety Information” (page 23).
An overview of the PCI installation procedure follows:
1. Extend the server from the rack by removing the two 25mm Torx screws that retain it in the
rack and flip out the server’s two pull handles. Use these handles to pull the server from
the rack until it locks in place and the cover is accessible (see callout 1 in Figure 1-28).
