Routing Fiber-Optic Cables - HP Surestore 64 - Director Switch Planning Manual

Routing Fiber-Optic Cables

The director has a maximum of 16 FPM cards (64 ports) that may require fiber-optic cable
connections and subsequent cable routing. In a Fibre Channel protocol OSI environment,
ports are numbered by physical port number only. Figure 15 shows FPM card numbers (0
through 15) and port numbers (00 through 63).

Figure 15 FPM Card and Port Numbers (OSI)
Connect cables to ports starting with the top port on all FPM cards, then use the second
port on all FPM cards, and continue working downward. Leave enough slack in the cables
to allow cable movement for FPM card 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 rack using cable ties provided. When routing fiber-optic cables and estimating
cable lengths, consider:
• Cable routing inside the equipment rack to different FPM card locations, and
installation position of the director (top or bottom of the rack). Plan for 1.0 meter (39.37
inches) of extra cable for routing through restraint mechanisms and rerouting cables to
other FPM cards.
• Cable routing outside the equipment rack. Plan for 1.5 meters (59.05 inches) of cable
outside the rack to provide slack for service clearance, limited rack movement, and
inadvertent cable pulls.
• Cabling distance to servers, storage devices, and directors (for multiswitch fabric
support).
