PCI+ IB_SSC Assemblies
Note – Do not mix different cards with different speeds within an IB6 leaf (two
paired slots), because leaf slots run at the lowest speed and the lowest mode for a
given set of cards within a leaf. For example, if a 33 MHz PCI card is in slot 0 and a
66 MHz PCI card is in slot 1, then both slots on the leaf will run in the lower 33 MHz
PCI mode. IB6 leafs are comprised of paired slots 0 and 1, 2 and 3, and 4 and 5. In
addition, all slots will only run in PCI+ mode.
PCI+ IB_SSC assemblies provide six PCI+ slots labeled 0 through 5. When viewing
the rear of the server, slot 0 is on the left and slot 5 is on the right. All six slots
support up to 66 MHz. The PCI+ slots are not hot-swappable, all slots are half length
and 5V signaling is not supported.
