Fibre Channel Cable Precautions
Keep the following precautions in mind when installing, handling, moving,
connecting, and disconnecting Fibre Channel cables:
■
Affix cable labels carefully, without over-tightening, to avoid breaking
the glass fibers within the cables.
■
Do not bend the Fibre Channel cable into an arc tighter than the
minimum allowable bend radius specified by the cable manufacturer.
The minimum bend radius is usually 10 to 20 times the outer diameter
of the cable. Protect the cables from pinching, abrasion, excess tension,
and any other mechanical stress.
■
When inserting or removing connectors, handle the Fibre Channel cable
only by the connector body, not by the strain relief or by the cable body.
Even moderate amounts of tension or pressure on the Fibre Channel
cable body can destroy the connector.
■
Type SC connectors include a white stripe along each side. Verify that
the connectors mate with a positive click and that the white stripe is
invisible. If the white stripe is visible, the connectors are not properly
mated.
■
Do not subject connectors to abrasion, chemical contaminants, or rough
handling. Fibre Channel mating surfaces are cut, polished, and aligned
to extremely close tolerances, and they are much more sensitive to
mishandling than conventional electrical signal connectors.
■
Do not allow dust to enter the connectors.
■
Leave any protective dust covers on the GBIC-SW whenever it is not
connected to a Fibre Channel cable.
■
Failures caused by dust contamination or improper cable connector
handling can exhibit the same symptoms as a controller or GBIC-SW
failure, resulting in an unnecessary component replacement that does
not resolve the root cause of the problem.
