4: IX-brick

Product Overview

66
The 4U-high IX-brick, shown in Figure 4-1, provides 12 PCI-X slots that support up to 12
PCI or PCI-X cards. The 12 slots are configured as six 2-slot buses.
Note: You can install PCI cards in 11 of the 12 PCI slots. One slot (the leftmost slot) is
reserved for an IO9 PCI card. This card is required for the base I/O functions.

The IX-brick is the follow-on product of the I-brick. Compared to the I-brick, the IX-brick
offers the following enhancements:
• The IX-brick supports both PCI and PCI-X cards.
• The IX-brick can have two or four serial ports. The first two serial ports are standard
components of the IX-brick (similar to the I-brick). The third and fourth serial ports
reside on a daughtercard that you can purchase as an optional component.
Note: The serial-port daughtercard requires the space of one PCI-X slot, but it does
not connect to the PCI-X bus.
