Task 2: Plan Fibre Channel Cable Routing

Plan for sufficient single-mode fiber-optic and multimode fiber-optic cabling to
meet the connectivity requirements for all Fibre Channel servers and devices. If a
multi-switch fabric is to be enabled, plan for sufficient fiber-optic cabling to meet
interswitch link (ISL) connectivity requirements.
Plan for at least one meter (39.37 inches) of fiber-optic cable inside the equipment
rack for routing to product Fibre Channel ports as required. Plan for an additional
1.5 meters (5 feet) of cable outside the rack to provide slack for service clearance,
limited rack movement, and inadvertent cable pulls.
In addition, consider the following when planning cable routing:

WARNING:
Director and switch non-open fiber control (non-OFC) laser
transceivers are designed and certified for use only with fiber-optic cable and
connectors with characteristics specified by HP. Use of other connectors or
optical fiber can result in emission of laser power levels capable of producing
injury to the eye if viewed directly. Use of non-specified connectors or optical
fiber can violate the Class 1 laser classification.
The need for additional fiber-optic cables could grow rapidly. Consider
installing cable with extra fibers, especially in hard to reach places like
underground trenches. Consider locating the equipment rack near a fiber-optic
patch panel.
Follow proper procedures when moving an installed equipment rack to
prevent cable or connector damage.
