Re: RJ 45 Aggravation Update
I do, I think part of my problem is I only work on this stuff every several years or so. Thanks On Dec 20, 2010, at 9:38 PM, gifutiger wrote: Greetings May I ask if you have a pair of RJ-45 crimpers?

The point of the crimper is to make the little spikes dig thru the insulation into the wire, to make a good connection. Alignment is, of course, critical. It also helps to hold your tongue just right and mutter an incantation as you squeeze. How many of the pairs does RJ 45 use? 100Base uses four wires, as two twisted pairs. The twists and the other wires provide shielding. 1000Base uses all of 'em. There should be some good wikipedia articles on ethernet over twisted pair that describes this stuff. - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Mark Murphy It worked because it is probably just using pairs 12, and 36. It sounds like bad or cheap plugs. We had a problem like that at a school in central Texas. It sometimes took 4 or 5 times to terminate a cable correctly because the plugs were faulty. The outer sheath of the cable should be about 1/2 inch back from the end of the wires. The outer sheath has to go up into the plug and be crimped inside it for stress relief. The cable's, not yours.
