v Each PCI-X DDR slot is a separate PCI host bridge (PHB).
v All slots are compatible with PCI and PCI-X DDR adapters.
v Short adapters can go in long slots.
Slot priorities
Slot priority for all adapters is 1, 4, 2, 5, 3, and 6. For a list of supported adapters, see the placement
information for the base system unit to which the expansion unit is attached.

PCI slot priorities for the 5802 and 5877 expansion units

Learn about the PCI Express (PCIe) slots in the 5802 and 5877 expansion units.
System description
The 5802 and 5877 expansion units are 19-inch, rack-mountable, I/O expansion drawers that are designed
to be attached to the system by using 12X double data rate (DDR) cables.
The expansion units can accommodate 10 generation-3 cassettes. These cassettes can be installed and
removed without removing the drawer from the rack. The expansion units do not support I/O processor
(IOP) adapters.
Notes:
v PCIe2 adapters that provide extra-high bandwidths aren't supported in the 5802 and 5877 expansion
units.
v If a PCI adapter with CCIN 577D is installed in location P1-C4 of a 5802 or 5877 expansion unit, do not
complete the install procedure for the PCI adapter in location P1-C5 with the system power on. The
install action with the power on might cause the PCI adapter in location P1-C4 to fail.
v If a PCI adapter with CCIN 577D is installed in location P1-C4 of a 5802 or 5877 expansion unit, you
can complete the remove and replace procedures for the PCI adapter in location P1-C5 with the system
power on. The remove action and the replace action of the PCI adapter in location P1-C5 with the
power on does not cause the PCI adapter in location P1-C4 to fail.
