Pci Adapters Slot Priorities For The 58/02 And 58/77 Expansion Units - IBM E1-700 Manual

PCI adapters slot priorities for the 58/02 and 58/77 expansion units

Learn about the PCI Express (PCIe) slots in the 58/02 and 58/77 expansion units.
System description
The 58/02 and 58/77 expansion units are 19-inch, rack-mountable, I/O expansion drawers that are
designed to be attached to the system 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.
Note: Extra-high bandwidth, PCIe2 adapters are not supported in the 58/02 and 58/77 expansion units.

Slot priority
The slot priority for all adapters is P1-C1, P1-C4, P1-C2, P1-C5, P1-C3, P1-C6, P1-C7, P1-C8, P1-C9, and
P1-C10.
There are three I/O chips. Each I/O chip controls three or 4 PCI host bridges (PHBs) and each PCIe slot
connects directly to a PHB.
v One I/O chip controls slots P1-C1, P1-C2, and P1-C3.
