Pcie I/O Drawer And I/O Drawer Features; Z13S (One Cpc Drawer) I/O Drawer Configurations; Z13S (Two Cpc Drawers) I/O Drawer Configurations - IBM z13s Technical Manual

In Figure 2-2, the various I/O drawer configurations are displayed when one CPC drawer is
installed for both Model N10 and N20. The view is from the rear of the A frame.
PCIe drawers are installed from the top down
An I/O drawer (legacy) is only present during a MES carry forward and is always at the
bottom of the frame.
