154 IBM z13s Technical Guide
Fanout features that are supported by the z13s server are shown in Table 4-5. The table
provides the feature type, feature code, and information about the link that is supported by the
fanout feature.
Table 4-5 Fanout summary
4.7 I/O features (cards)
I/O features (cards) have ports
4
to connect z13s servers to external devices, networks, or
other servers. I/O features are plugged into the PCIe I/O drawer, based on the configuration
rules for the server. Different types of I/O cards are available, one for each channel or link
type. I/O cards can be installed or replaced concurrently.
In addition to PCIe I/O features, FICON Express8 features can be installed in I/O drawers.
z13s servers support a maximum of one I/O drawers as carry-forward during an MES. This
drawer represents a maximum of 8 FICON Express8 features (a total of 32 FICON Express8
ports) that can be carried forward.

Certain I/O features do not have external ports, such as Crypto Express5S and zEDC
Consideration: The installation of an I/O drawer limits the LPAR storage to 1 TB
(independent from the IOCP definition). Moreover,
each I/O drawer affects the
configuration as follows:
The total fanout slots for PSIFB are reduced by two.
