How to crimp a twisted pair connector RJ45 / 8P8C

Crimping the connector is carried out with a special crimping tool (crimping pliers), in extreme cases if they are not available you can use a flat thin screwdriver. First carefully remove the 3 centimeters of the upper braid cable, weave pairs of conductors and align in a row according to the standard that we need. Superfluous ends cut off to about 1cm remained. We put it into the connector so that the conductors have reached the very end of the connector and have rested, the outer insulation of the cable should also as far as possible go into the connector. We check that the colors are not messed up when inserting, we insert it into the crimper and squeeze. Done.

Twisted pair crimp standards:
1) direct link, the most used, is often used to connect a computer with a switch, a router, etc. Both connectors are crimped the same way.
white-orange / orange / white-green / blue / white-blue / green / white-brown / brown


2) cross-link, it is used to connect two computers to each other, but in our time computers can be connected and the cable is compressed by the standard above, so it is used quite rarely. One connector is crimped as indicated below, the second as indicated above.
white-green / green / white-orange / blue / white-blue / orange / white-brown / brown

Connecting SFP-RJ45 Modules to the Cisco 6500

It took a couple of days ago to the Cisco Catalyst 6509-E in which there were modules only with SFP ports to connect a few links with RJ45.

Since RJ45 links are small, it was more economical to use SFP-RJ45 modules, so they were ordered.
I connected them to the ports WS-X6724-SFP, but nothing was displayed in the logs.

Let’s write commands so that Cisco does not disable ports when inserting unsupported modules:

service unsupported-transceiver
no errdisable detect cause sfp-config-mismatch
no errdisable detect cause gbic-invalid

I note that the ports WS-X6724-SFP in my case work only at 1Gb speed, so the link will not naturally rise to 100Mb or 10MB, although the Foxgate SFP-RJ45 modules that we had and support 10/100/1000.

In confirmation of this I checked the commands:

configure t
interface gigabitEthernet 1/1
speed ?

What was the opportunity to specify the speed of the port only in 1000.
