Q3: Why do we use Wall Jacks?
A3:If there is no wall jack, one has to get enough spare cable for allowing
relocation of the workstation. In this case, he may get too much cable
coiled up in every station for future purposes. With a wall jack, he can
get a patch cable of the best length and replace the patch cable if there
is any relocation.All the wear and tear is mainly on the cable plant.With
a wall jack, cable failures are much more likely to be in the patch cables,
and it is always easy to swap out a patch cable when there is any cable
problem.
There are actually a number of components that make up a wall jack.It
comprises a wall plate and a wiring box together with an RJ-45 connector.A
wall plate lets you add a label identifying the information outlet. The
identification should always be the same as the label on the patch panel
in the wiring closet. The wiring box is pretty much like an electrical
wiring box. It provides something to affix the wall plate to and a place
for some slack cable.
The connectors will have an RJ-45 on the front and has a 110-style connector
on the back, color-coded either with 568A or B to match the color of the
cable pairs.Every wall plate should be wired the same (568A or 568B) way
and must also match the style on the patch panel. |
