CHAPTER 4: Operation
NOTE
When you attach the wires in your Category 5 cables to the
Black Cat CAT5 Patch Panel, be careful not to let the pairs
untwist more than a half-inch (13 mm). Because NEXT and
other electrical performance features are affected by twist,
in EIA/TIA-568 the EIA and TIA specify “preserving wire twist
as closely as possible to the point of mechanical
termination.” In addition, TSB-40 declares that “the amount
of untwisting in a pair as a result of termination to connector
hardware shall be no greater than 13 mm (0.5 inches) for
Category 5 and shall be no greater than 25 mm (1.0 inch)
for Category 4 cable.”
5. Place the ends of the eight individual wires in the
cable across the contact gaps in the Panel’s Type
110 connector, with the ends of the wires toward
the
outside
(toward the
edge
of the Panel). The white-
with-colored-stripe (white/colored) wire must be
placed to the left of the correspondingly colored
prong and the colored-with-white-stripe (colored/
white) wire to the right of the prong. For example,
place the white/brown wire to the left of the brown
prong and the brown/white wire to the right of the
brown prong.
6. Position an Type 110 punchdown tool over one of
the wires, with the tool surface labeled “CUT”
toward the
outside
(toward the
edge
of the Panel), as
shown in Figure 3-2 on the next page.
