Label the System Wiring
If done correctly, labeling can provide valuable information about
the location of wire or cable within the building and save hours of
frustrating work.
There are five types of labels used for identification:
Cable labels. Cable labels are white adhesive-backed tabs
that are stuck to the cables to identify the source and the
destination of the cables before they are pulled to and
terminated in satellite closets and equipment rooms. The
labels come in a variety of shapes and sizes to accommodate
different sizes of cable. Use a pen or a felt-tip marker to write
on the surface.
Field labels. Field labels are adhesive-backed tabs that are
applied to smooth surfaces in the equipment room and
satellite closets. They identify components. Use a pen or a
felt-tip marker to write on them.
Insert labels. Insert labels are cardboard-like strips that slip
inside the clear plastic designation strips located between the
rows of a termination or field-terminated wiring block. They
are color-coded to identify the origins of cables.
Along with the color-coding scheme, alphanumeric codes on
the labels help to identify the specific location of the same
pair or series of pairs at the other end of the cable (see
Table 3-34).
Jack labels. Jack labels are small, white, rectangular-shaped
stick-on tabs that are stuck to the cover plate or housing of
station outlets. They identify the location of the satellite closet
where the cable to that outlet is terminated and the number of
the circuit.
Station cord labels. The blue station cord labels are
packaged with the CU carriers and wrap around each end of
the station cords leaving the CU.
