Chapter 6. Cabling and ConnectivityCable Installation PlanningBefore you place your cable order, consider your future growth needs. Youmay wish to order cables longer than you need right now to avoid expansionproblems in the future.As processor packaging evolves, internal locations for various cableconnections may shift, necessitating longer cables, even though the floorlocations of connected devices have not changed.The zSeries 800 family recognizes industry trends toward the use of standardizedchannel cable connectors. The same types of fiber optic connectors used in localarea and storage area networks are also used to connect channel features in thezSeries 800.Following are:v A description of the new zSeries Fiber Optic Cabling Service and a list ofcustomer responsibilities if you elect not to use the servicev A chart showing the various fiber optic cable connectorsv An illustration showing how to correctly route fiber optic cables to provide propercable strain relief and ensure design performance.v Descriptions of the channel features for the zSeries 800 system, including theFiber Quick Connect trunking system for ESCON cables.Note: The Fiber Quick Connect trunking system cannot be used in a non-raisedfloor installation. There is not enough space to obtain correct cable bendradius at the tailgate exit area.zSeries Fiber Cabling ServiceThe connectivity environment has become much more complex, and properplanning and installation of fiber cabling is critical to maximize the benefits of highspeed protocols such as FICON, Fibre Channel Protocol, Coupling Facility links andGigabit Ethernet. These protocols require planning for different fiber types, new fiberoptic connectors, and current and future data rates to determine optimalconnectivity and cabling options.IBM Global Services provides a fixed-price services offering that includes planningand consulting with you about your cabling choices, and ordering, labeling, andinstalling the correct cables for your system.
