Question about Cat5e Cat.5E RJ45 Modular Plug, 1 Prong (Bag of 100) (337311)

Using patch panel fields and patch cables versus running cat5e and field crimping a modular RJ45 end

I have a heated debat going on with my IT folks regarding the use of patch panel fields and patch cables versus running a cat5e cable and filed terminating a crimp style rj45 end. I know what the standared dictates but I would like some more reasons patch panels and patch cable should be used as our IT folks insist that using patch panels just creates an additional fail point and is not a better solution than using crimp mod ends and connecting equipment directly without a patch cable or panel in between.

    The 8-pin plug is terminated on solid cabling. I agree with you 100%, do you have any reference materials stating so? BICCI or EIA/TIA references? I have to provide hard facts and back it up time and time again. The last information I sent them follows:



    BICSI

    TDMM (10 Edition)

    Chapter 5

    “Horizontal Connecting Hardware”

    Page: 5-114

    “Equipment Connections”

    “Do not connect horizontal cable directly to telecommunications equipment. Instead, use suitable connecting hardware and equipment cable to make connections. Locate patch panels and cross-connect blocks so that the combined length of cables and cords used to connect equipment in the work area and TR, plus the patch cable, does not exceed 10m (33ft.).”



    Here is another example of the input of our data/IT folks:

    I don’t think a patch panel solution would resolve the open ended cable issue. All the RJ 45’s will still be prone to moves making the cable labels wrong and the disconnected cables laying around could still happen. The difference being now the RJ45’s with these issues are located at a main patch panel(s) instead of at the big iron. The type of connector used on the back side of the patch panel is a concern as well. If the back side of the patch panel is a punch down style instead of a locking style we will be susceptible to having the cables pulled off of the back of the patch panel by tension as other cables are moved around.



    Don't you just love it?

    Thank you for your input it is greatly appreciated.

I would tell you what I think of your IT folks, but I don't want you to rate this response as IA :-)

Yeah, they have a point. Wiring point-to-point does cut down the chances for failure....provided they used the proper plugs and don't plan on moving them around. It gives them job security because you have to label each cable and when the tags fall off, only they know where the cables go. Plus, a structured cabling system give you, well, STRUCTURE. You're not at the mercy of the guy who "crimped" some imported 8-pin plug on a piece of wire. Wait were those solid or stranded wire plugs? It may run 10 Base T, but it is unlikely that it will run 1000 Base T.

A proper infrastructure contains a patch panel properly labeled and jacks at the computer end, with patch cords of various lengths to the computer and switch. We're a Leviton house, so the link is to their web site.

Just my opinion.

No connection, have checked cable connection each end without plugging it into the patch panel and it works, plug it into the patch panel nothing? Could the patch panel be faulty?


Do you mean that you tested the patch lead that connects the patch panel and the hub?
OR
The RJ45 connection at the workstation (one end) and the RJ45 connection at the patch panel (at the other end)?
If these checked out OK then the RJ45 connection at the hub could be faulty, try a different port on the hub, do you get a link light?
The LAN card in the conputer could be faulty, try another computer at the "faulty" workstation to check the network connection.

I have a broadband DSL modem/router in my home office. I also have 2 CAT5e ports there. I want to feed the Internet signal from the router (one of the ports on the back) through a CAT5e point up to my...


Hi Joe,

How are you connecting to the port in the back of your router? if you have crimped a male plug on to some UTP cable then this may be the problem. UTP cable has a solid condutor and needs a different male crimp plug than UTP patch cable, which has stranded conductors.

I suggest you connect the UTP cable between the office and the loft to an RJ45 wall or surface socket in the office, use a terminating tool designed for the make and type of outlet you use, i.e. if using an ADC socket use the ADC termination tool. The sockets are designed for solid cable and have a colour code for you to follow. Then use a factory terminated patch cord between this socket and the router port.

I assume you have terminated the cable from the office onto one of the patch panel ports and want to use a patch cord to patch from this incoming socket to the sockets that are terminated onto the cables going to your other rooms. If you have access to a laptop connect this directly into the router port and ensure you have an internet connection, then plug the patch cord connecting the loft port into the router and take the laptop into the loft and ensure you have a connection at the incoming port on the patch panel. If you get the connnection there then use a factory patch cord to patch to a room you would like a connection in and then take the laptop to that outlet and ensure you have a connection.

If you want to run outlets in multiple rooms without re-patching every time then you will need to have an active switch in your loft and connect the port from the office to this and then patch out of the switch ports to the various room outlets.

Hope this helps.

Cheers, Jason

Plz explain me exactly for which purpose RJ-45 cable used ?


RJ -45 is a type of connector used on cat5, cat5e....etc cables to connect networked devices...the RJ stands for registered jack but there is really not much you really need to know about it....a RJ 45 JACK is a little bigger than a telephone jack, you'll notice the female type of input on your computer or laptop and the male end will be on the end of the cable that goes into this jack....hope this helps

Ethernet cable end repair


Unless you have a RJ45 crimping tool you are stuck with having to ask someone who does have one to borrow it, honestly if you know someone with a crimping tool then ask them to perform the repair.
If however you have the tool for a straight through cable (most common)
Holding the plug upside down (catch towards the floor) and the pins furthest away from you I use the following layout;

orange white (furthest left hand side)
orange
green white
blue
blue white
green
brown brown white (furthest right hand side)

slide the cables into the plug held in the position describe above, then check the order of each wire once more using the crimping tool to "crimp the new RJ45 connection in place.

Basically as long as you hold the rj45 connector in the same position the wires should go into the same corresponding position at each end.
