Physical Planning Considerations

Routing Fiber-Optic

Cables

Follow a logical plan for routing fiber-optic cables to avoid confusing

connections during installation and operation. Route cables from the

access holes at the bottom of the Fabricenter equipment cabinet to

fabric element ports. When routing cables to ports be aware:

• In a Fibre Channel Protocol (FCP) environment, ports are

numbered by physical port number.

• In a fibre connection (FICON) environment, ports are numbered

by logical port address. The translation between physical port

number and logical port address varies by equipment type and

original equipment manufacturer (OEM).

Figure 3-17 and Figure 3-18 illustrate port numbering and logical port

addressing for the Intrepid 6140 Director. Although the figures depict

a UPM card map only for the Intrepid 6140 Director, physical port

numbers and logical port addresses can be extrapolated for other

switch products.

Leave enough slack in the cables to allow cable movement for FPM

card, UPM card, XPM card, LIM, or SFP optical transceiver removal

and replacement or possible rerouting of the cable to another port.

After cables are routed and connected, secure the cables to the sides

of the cabinet using cable ties provided. When routing fiber-optic

cables and estimating cable lengths, consider:

• Cable routing inside the equipment cabinet to different port

locations, and installation position of the director or switch (top

or bottom of the cabinet). Plan for 1.0 meter (39.37 inches) of extra

cable for routing through restraint mechanisms and rerouting

cables to other ports.
