Table 3-8 Spanned and shared channels
Note that while the PCICA and PCIXCC cryptographic features do not have CHIPD types and
are not identified as spanned channels, all logical partitions in all LCSSs have access to the
PCICA feature, up to 30 logical partitions per feature, and all logical partitions in all LCSSs
have access to the PCIXCC feature, up to 16 logical partitions per feature.
I/O features cables and connectors
IBM Fiber Cabling Services offer a total cable solution service to help with your cable ordering
needs, and is highly recommended. These services take into consideration the requirements
for all of the protocols/media types supported on zSeries (for example, ESCON, FICON,
Coupling Links, OSA), whether the focus is the data center, the Storage Area Network (SAN),
Local Area Network (LAN), or the end-to-end enterprise.
The Enterprise fiber cabling services employ the use of a proven modular cabling system, the
Fiber Transport System (FTS), which includes trunk cables, zone cabinets, and panels for
your servers, directors, and storage devices.
FTS supports Fiber Quick Connect (FQC), a fiber harness integrated in the zSeries frame for
“quick” connect, which is offered as a feature on zSeries for connection to ESCON channels.
Whether you choose a packaged service or a custom service, high quality components are
used to facilitate moves, adds, and changes in the enterprise to prevent extending your
maintenance “window”.

Attention: All fiber optic cables, cable planning, labeling, and installation are customer
responsibilities for new z990 installations and upgrades. Fiber optic conversion kits and
Mode Conditioning Patch (MCP) cables are not orderable as features on z990 servers;
only ICB (copper) cables are orderable. All other cables have to be sourced separately.
