Patch Panels |
|
|
I'm currently studying for my Network+ Certification exam and I came
across patch panels in my reading and I understand that they provide a
safe place for all the cables, organization, as well as providing
flexibility. But my reading was vague on the connection provided by
the patch cables from the panel to the hub. Does each connection to
the patch panel need its own patch cable to the hub, and if so, why
would one want to even bother with a patch panel if every thing needs
to connect to a hub anyways? Also, can a network opperate through a
patch panel with out the use of a hub, switch, etc...? I assume not,
but just in case. If anywould would be willing to explain this patch
panel stuff to me that would be great.
Thanks,
David |

The theory of patch panels is that you can have many jacks and less
hub/switch ports. It may not matter a whole lot in today's $130 for
24 port unmanaged switches, but in the "old days" or in managed
hubs/switches it mattered a lot.
I always tell a customer that "cable is cheap". Decorate a room with
3 or 4 network locations and you don't care where the user sits. He
only might need a single port on a switch but he might have 8 jacks in
his room. When it comes time to rearrange his space, he just moves
the computer to the new jack and moves the corresponding patch cord in
the computer room.

Yes, 1 cable = 1 connection. The reason the patch panel is there is that
you can use your cabling for more that just Ethernet. If the system is
designed properly, you can easily switch between Ethernet, digital or
analog phone or fax, CCTV camera and other devices, provided by you
connect to proper equipment in the closet. The patch panel gives you
ability to move your cable's connection between different devices and not
only Ethernet hubs or switches.
One other important use of the patch panel is elimination of crimping
(when you’d directly crimp your RJ45 jacks on the end of the cable).
Crimping is a very error-prone and inefficient (time wise) installation
procedure, and the use of the patch panel makes the installation a lot
easier.

We're getting ready to populate our new bldg with over 680 data drops
(if the contractor gets thru with installing them before xmas! Doesn't
look like it). Man, boxes and boxes of patch cables taking up space in
the corner of the server room. Anyway, they're all imported cables,
cat6, with the two-part connectors. It's enough hassle to crimp the
regular one piece connectors, I don't know what it's like for the
two-part ones. With ever more critical specs for the cabling system,
it's really not worth doing your own patch cords. They're only a few
bucks at the local electronics store, or get them online for even
cheaper on Ebay or Gruber industries or whatever.
If the store wants more than a few dollars for a short patch cord, take
your business elsewhere. I've noticed that some stores get you into the
store with a sale, then gouge you with the extras such as USB cables,
power strips, speaker cables, etc. Their markup is literally a thousand
percent. They want $26 to $31 for a 6 foot USB cord, when you can get
them for $3 on Ebay, or $6 at Fry's. And don't get suckered into those
extended warranties either. For the store, those are a license to steal
your money. KABC had a good piece on extended warranties a day or so
ago, but I went here,
http://abclocal.go.com/kabc/features/consumer/index.html
did a control F, and typed in warrant, and it found the article, but
when I clicked on it, it gave URL not found. Maybe you'll have better
luck later. A lot of other good articles there, too, like the one about
the cell phone batteries catching on fire(!)

Dmitri,
Speaking of crimping ends...LOL
Went out to a school district today that uses nothing but crimped ends
HAHA no patch panel at all. Surprisingly no problems.
I told them thats not the right way to do it. Their "computer guys"
told them to do it that way... |

Re: Patch Panels |

In office and control room installations the best bet seems to be to use
female/female patch panels and then use pre-made patch cords for both the
switch/hub connection and for the horizontal section. This allows one to go
directly to the end device or wall outlet with a tested, certified cable
obviating the need for on-site certification. For industrial plant
installations, it is probably best to use a pre-made patch cord to go
directly from the switch/hub to the end device. So many connections in the
way with the traditional patch panel in the route degrade network
(connector) reliability and complicate documentation, testing, tagging, and
maintenance troubleshooting.
