I have run into this a couple of times so I thought I would let you fellers know. Ocassionally when I crimp an 8P8C AMP plug onto a Category 5 cable and insert it into a jack on a Linksys switch I get an intermittant connection. The problem is not my assemply, the problem seems to be the insulators between the conductors on the plug are too high to let the contact pins in the Linksys RJ-45 plug make good contact with the mod plug. Rocking the mod plug will definately open the connection and sometimes I can not get a good connection at all.

Terminating the cable on a female RJ-45 jack and using a factory patch cord between the jack and the Linksys solves the problem. I have tested my cable and changed the plug many times in coming to this determination. I have not had this problem with any other switch.

There's a good answer to that....Don't crimp, but outside of that you said AMP are you using a genuine AMP tool to crimp? It's made differently than any other tool.

crimping solid wire patch cords just isn't worth it ...even if it works now it may have problems later as it flex's and moisture creeps into the crimp

Plugs are designed to work with either solid or stranded wire. Make sure the plugs match the wire.

Also make sure it's not your tool.

The crimper may be worn to the point that it's not crimping hard enough.

Do it right...."jack & patch"

Maybe the tool is scraping the plastic between the pins and causing burrs that catch the pins in the jack. I've used hundreds of AMP ends with an Ideal crimper without any issues, but cheaper tools may not work as well.

I'll just echo the statement that you should not crimp mod plugs onto solid cable. Even if you are using the correct plugs, made for solid wire, they are still MUCH more likely to fail. When it does fail, the customer can't exactly swap out a patch cable to troubleshoot.

I have not had this problem with any other switch.

Sure, blame the equipment. It couldn't possibly be you, right?

I have to laugh. Sparkies and CGs go to the likes of Home Dumpo or flea bay and spend $20 on a plug presser (crimper to you sparkies and CGs) and they think they are all set. Spend $200 for a decent presser and buy the proper plugs for the wire you are using from Amp and you won't have a problem.

Then again if you had to spent that kind of money you'll probably not want to put plugs on cables which is the better solution to begin with.

"using a factory patch cord between the jack and the Linksys solves the problem."

Factory patch cord solved the problem!

No?

I have two AMP and one GMP presser , plugs for stranded and solid cable and I still press plugs for Ethernet rarely and only as a last resort

we've discussed it before but I can provide a factory made patch cord for less than the T&M to make a inferior one on site '
