Task 2: Plan Fiber-Optic Cable Routing - HP Surestore 64 - Director Switch Planning Manual

Task 2: Plan Fiber-Optic Cable Routing

Plan for sufficient singlemode and multimode fiber-optic cabling to meet the connectivity
requirements for director-attached servers and devices. If a multiswitch fabric is to be
enabled, plan for sufficient 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 through director cable management assemblies and for rerouting cables to fiber
port module (FPM) cards as required. Also, plan for an additional 1.5 meters (59.05 inches)
of cable outside the rack to provide ample service clearance, limited rack movement, and
inadvertent cable pulls.
C When equipped with native Fibre Channel adapters, this product contains a
AUTION
laser internal to the small form factor pluggable (SFP) transceiver module on
the 4-port FPM cards.
In the USA, the SFP module is certified as a Class 1 Laser product, conforming
to the requirements contained in Department Of Health and Human Services
(DSHS) regulation 21 CFR, Subchapter J. The certification is indicated by a
label on the metal SFP housing. Outside the USA, the SFP is certified as a Class
1 Laser product conforming to the requirements contained in IEC 825-1:1993
and EN 60825-1:1994, including Amendment 11:1996.
Each communications port consists of a transmitter and receiver optical
subassembly. The transmitter subassembly contains internally a
semiconductor laser diode in the wavelength of either 850 nanometers
(shortwave laser) or 1310 nanometers (longwave laser).
In addition, consider the following when planning cable routing:
• 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.
