Installing Fiber-Optic ServerNet Cables
Installing Fiber-Optic ServerNet Cables
Before installing fiber-optic cables, note the following considerations:
Planning for Environmental Requirements
The following table describes the operating characteristics of the ServerNet Cluster
Switch.
Consideration Additional Notes
Review specifications
first.
Review the cable/connector specifications, routing procedures, and
your building’s floor plan where the fiber-optic cables are to be
routed. If you have questions or need further information, consult
the global customer support center (GCSC).
Treat the cable
assemblies with care.
Handle fiber-optic cables gently. Do not step on fiber-optic cables.
Avoid laying boards, pallets, tools, or anything else on them. Don’t
leave a cable where it might be run over by hand trucks, forklifts,
and so on. Keep cables out of any potential damaging area.
Observe all
regulations.
Review all applicable codes, especially National Electric Codes
NEC 770-6 and NEC 770-53. In addition, review other federal,
state, and local guidelines that might apply. These vary from
location to location. Consult local city engineers or building
inspectors if questions arise.
Always inspect and
test fiber-optic cable
assemblies before
installation.
Visually inspect shipping containers, fiber-optic connectors, a
cable’s outside jacket, and spool. Test the fiber-optic cable for
attenuation loss before uncoiling the fiber-optic cable. Record all
findings.
Always leave extra
cable.
Some slack in a fiber-optic cable is essential; therefore, don’t pull it
up too tight. If a junction connector is used, consider leaving two
loops at each junction. In a riser routing scheme, consider leaving
two loops at the top of the riser.
Don’t exceed the
maximum bend radius
of the cable.
The bend radius for these fiber optic cables should be 45 mm (1.8
inches). Be sure all the path areas of a fiber-optic cable does not
require a bend tighter than the cable’s maximum bend radius
specification.
Store extra fiber-optic
cable on the shipping
spool.
All extra fiber-optic cable should be kept on the shipping spool and
reside under the raised floor, if used, or in some other protected
location.
