The Enterprise Fiber Cabling Services use a proven modular cabling system, the fiber  transport system (FTS), which includes trunk cables, zone cabinets, and panels for servers,  directors, and storage devices. FTS supports Fiber Quick Connect (FQC), a fiber harness  that is integrated in the frame of a z14 server for quick connection. The FQC is offered as a  feature on z13 servers for connection to FICON LX channels. Whether you choose a packaged service or a custom service, high-quality components are  used to facilitate moves, additions, and changes in the enterprise to prevent having to extend  the maintenance window. The required connector and cable type for each I/O feature on IBM z14™ servers are listed in  Table 4-6.
