Figure 2-23 shows the location of the fanouts for a Model N10. Model N10 has four PCIe
fanout slots and two IFB fanout slots. The CPC drawer has two FSPs for system control.
LGXX
is the location code.
Up to 4 PCIe fanouts (LG11 - LG14) and two IFB fanouts (LG09 - LG10) can be installed in
the CPC drawer.

Figure 2-24 shows the location of the fanouts for a Model N20 with two CPC drawers. Each
CPC drawer has two FSPs for system control.
LGXX
is the location code. If the model is a
N20 single CPC drawer system, only
CPC drawer 1
is installed.
Up to 8 PCIe fanouts (LG03 - LG06 and LG11 - LG14) and four IFB fanouts (LG07 - LG10)
can be installed in each CPC drawer.

A PCIe Generation 3 fanout connected to a PCIe I/O drawer can be repaired concurrently
with the use of a redundant I/O interconnect. For more information, see 2.6.1, “Redundant I/O
interconnect” on page 67.
Five types of fanouts are available:
򐂰 PCIe Generation 3 fanout card: This copper fanout provides connectivity to the PCIe
switch cards in the PCIe I/O drawer.
򐂰
Host Channel Adapter (HCA2-C): This copper fanout provides connectivity to the IFB-MP
cards in the I/O drawer.
򐂰 Integrated Coupling Adapter (ICA SR): This adapter provides coupling connectivity
between z13s and z13/z13s servers.
򐂰
Host Channel Adapter (HCA3-O (12xIFB)): This optical fanout provides 12x InfiniBand
coupling link connectivity up to 150 meters (492 ft.) distance to z13s, z13, zEC12, zBC12,
z196, and z114 servers.
